I have just finished implementing add new person routine for you. I hope you can do the rest. // The "PhoneBook" class. package Menus; import java.util.*; public class PhoneBook extends Object{ private static char INVALID_OPTION = 'q'; private static char answer; private static BasicMenu menu; private static Person person; private static Vector list; private static String options[] = {"Add new person", "Delete new person", "Modify person details"}; public static void main (String[] args){ list = new Vector(); menu = new BasicMenu("Phone Book Application", options, "Please make a selection"  ;while ( answer != INVALID_OPTION){ answer = menu.offerMenuAsChar(); switch( answer ){ case 'A': addPerson(); break; case 'B': deletePerson(); break; case 'C': modifyPerson(); break; }//End switch }//End while }//End main public static void addPerson (){ String fname = null; String lname = null; String tele = null; Person person; String options[] = {"Enter your First name: ", "Enter your Last name: ", "Enter your telephone number: "}; BasicMenu theBasicMenu; try{ java.io.DataInputStream keyboard = new java.io.DataInputStream( System.in); theBasicMenu = new BasicMenu("Add a person to the phone book list", options, "Enter your choice: " ;while ( answer != INVALID_OPTION){ char choice = theBasicMenu.offerMenuAsChar(); switch( choice ){ case 'A': System.out.println("Enter your first name: " ;fname = keyboard.readLine().trim(); break; case 'B': System.out.println("Enter your last name: " ;lname = keyboard.readLine().trim(); break; case 'C': System.out.println("Enter your telephone number: " ;tele = keyboard.readLine().trim(); break; }//End switch }//End while }catch ( Exception e){ //e.getStackTrace(); }//End try/catch person = new Person(fname, lname, tele); list.add( person); }//End addPerson public static void deletePerson(){ }//End deletePerson public static void modifyPerson(){ }//End modifyPerson } // PhoneBook class |

Here is some code I have managed to architect for you in managing your Phone Book application software. I have not implemented the routines for: 1. Add 2. Delete 3. Modify I believe you can do that yourself. I do not want to do your coursework for you. Good luck Code // The "PhoneBook" class. package Menus; import java.util.*; public class PhoneBook extends Object{ private static char INVALID_OPTION = 'q'; private static char answer; private static BasicMenu menu; private static Vector list; private static String options[] = {"Add new person", "Delete new person", "Modify person details"}; public static void main (String[] args){ list = new Vector(); menu = new BasicMenu("Phone Book Application", options, "Please make a selection" ;while ( answer != INVALID_OPTION){ answer = menu.offerMenuAsChar(); switch( answer ){ case 'A': addPerson(); break; case 'B': deletePerson(); break; case 'C': modifyPerson(); break; }//End switch }//End while }//End main public static void addPerson (){ }//End addPerson public static void deletePerson(){ }//End deletePerson public static void modifyPerson(){ }//End modifyPerson } // PhoneBook class // Filename Menus/BasicMenu.java. // Providing an initial Interactive Menu. // package Menus; public class BasicMenu extends Object { private String theTitle; private String theOptions[]; private String thePrompt = "Please enter your choice :"; private char minimumOption; private char maximumOption; private java.io.DataInputStream keyboard = new java.io.DataInputStream( System.in); public BasicMenu( String title, String options[], String prompt) { int thisString; if ( title.length() > 0 ) { theTitle = new String( title); } // End if. theOptions = new String[ options.length]; for ( thisString = 0; thisString < options.length; thisString++ ) { theOptions[ thisString] = new String( options[ thisString]); } // End for. if ( prompt.length() > 0) { thePrompt = new String( prompt); } // End if. } // End BasicMenu public char offerMenuAsChar() { char validatedResponse; this.showMenu(); validatedResponse = getValidatedMenuChoice(); return validatedResponse; } // End offerMenu public int offerMenuAsInt() { char responseAsChar = offerMenuAsChar(); return (responseAsChar - 'A') + 1; } // End offerMenu private void showMenu( ){ int thisString; char thisOption = 'A'; setMinimumOption( thisOption); showTitle(); for ( thisString = 0; thisString < theOptions.length; thisString++ ) { showMenuLine( thisOption, thisString); thisOption++; } // End for setMaximumOption( --thisOption); } // End showMenu protected void showTitle(){ if ( theTitle != null ) { System.out.println( "\t" + theTitle + "\n" ;} } // end fun showMenuOption. protected void showMenuLine( char menulabel, int menuText){ System.out.println( menulabel + ".

In the Entry class don't use ArraryList or Array because you have to worry about the growth and size of the array. If your requirements allows you to change the array, I would advice you to change it to a Vector Object. Because Vector grows and shrink by it self. However, looking at your routine enlarge(), you have taken care of that growth. But how about shrink? You do not want an empty entry record still in you memory. // The "Person" class. import java.io.*; public class Person extends Object { private String firstName="First name"; private String lastName ="Last name"; private String telephoneNumber ="Telephone number"; public Person (){ }//End default Constructor public Person (String firstName, String lastName, String telephoneNumber)throws Exception{ if ( ( firstName == null ) || ( lastName == null ) || ( telephoneNumber == null )) throw new Exception ("You must enter "+this.firstName+ " "+ this.lastName+ " "+ this.telephoneNumber ); this.firstName = firstName; this.lastName = lastName; this.telephoneNumber = telephoneNumber; }//End alternative constructor //Setters public void setFirstName(String firstName){this.firstName = firstName;} public void setlastName(String lastName){this.lastName = lastName;} public void setTelephoneNumber(String telephoneNumber){this.telephoneNumber = telephoneNumber;} //Getters public String getFirstName(){return this.firstName;} public String getLastName(){return this.lastName;} public String getTelephoneNumber(){return this.telephoneNumber;} } // FileExample class |

I don't really know what you are trying to accomplished with this limited code. Besides, the Object Person is not included for us to see their private and public fields and methods. Also, assert and count field/object where are they from? However, if you are trying to architect an Address Book artefact you would need these Objects or Classes 1. Entry 2. Person 3. AddressBook I don't have time to draw UML diagram for you but I guess you can do that, right? Entry Object will hold all the the following methods: 1. Edit function(s) 2. Add function(s) 3. Remove function(s) 4. Search function(s) 5. Retrieve function(s) 6. Store function(s) Now, for every entry into the Entry Object there must be one Person Object, you can check for duplicate entry and throw exceptions. For every AddressBook, there maybe several entries, therefore, you have M:1 relationship. Remember, since you are going to store the file on the hard drive, you are going to create a text file called addressBook.txt Use the I/O routine i.e try{ PrintWriter out = new PrintWriter(new FileWriter("adrressBook.txt" );}catch(Exception e){} To read the file use try{ PrintReader in = new PrintReader(new FileReader("adrressBook.txt" );}catch(Exception e){e.printStackTrace()} These routines should be in you Entry object routine like save contact |

Java enthusiast may have a try with javabb @uspry1 Ask the nairaland owner for an evaluation of SMF platform and compare it with others. I think BB (Black Board) should be used by an enthusiast of the language the platform it written with. Remember all BB are customisable And there is always new versions of BB throughout the year and it should be easy to integrate a newly version into existing platform. These should be your evaluation strategy for choosing BB. Example: 1. Easy database integration (MYSQL, ORACLE, HSQLDB, POSTGRESQL, etc) 2. Themes 3. Layout (Navigational Storyboard) 4. Installation 5. Programming Language (The language you know) 6. Hosting companies and their charges for various language support 7. Help from the BB Company 8. The forum and how easy to get a straight answer from their forum 9. Security of their BB 10. Failsafe These are in my opinion the things you should look out b4 deploying a BB solution |

@Hustler I know exactly what you want and you are going about it the wrong way as long as Nigeria is concern, I maybe wrong correct me people. I don't think Nigeria at the moment has a T1/E1 link because these infrastructure requires Fibre Optic. However, you need a Colocation in NGR to deploy your solution. Remember I was asking about any DataCenter in Nigeria on a different thread. Nevertheless, You can use current Nigeria wireless broadcast i.e Wi-Fi or an ISP. I think currently with Wi-Fi form IEEE, 802.11g and 802.11b etc the Wireless transponder can only operate at a band of 2.4GHz on (802.11b and 802.11g) at the data rate of 11Mbps and 5GHz on 802.11a at data rate 54Mbps You have to find ISP in Nigeria that use IEEE 802.11a solutions at least you can get more data rate, remember it is not dedicated the data rate is shared by the connected users. Ask them for a dedicated lease line. Furthermore, get a VSAT like 4 dishes assuming you are getting 128Kbps on each subscription from your ISP. Buy a single data entry point like Dlink DI-LB604 Load Balancing Router and combine the connection to up a 512Kbps, another 4 VSAT's you are a broadband user. Although, have 8 VSAT may seem daunting the solution my benefit from its deployment. Finally, when you have a nearly broadband solution you can deploy your solution. I have access to equipment to open a gateway between you and a GSM network, ISP network, PBX network, ILEC network, Wi-Fi network, HSDPA network Telecomms gateways and solutions to any Telecomm communication. I can help you with a terminator, not Nigeria. Nigeria terminator must be the main NSP(Network Service Provider) like Nigeria Telecom or a global Colocators like these giant GSM providers. But you don't need them. Their systems are feed to a more powerful gateways abroad, so you can access Nigeria gateway from abroad. I can provide you with carriers depending on your targeted customers and location. |

| Programming / Re: A Simple C++ Program That Evaluates A Simple And Compound Interest by sbucareer(f): 10:54pm On May 01, 2008 |
First let start by elaborating what is meant by compound interest. Compound interest is interest that is paid on both the principal and also on any interest from past years. Therefore, It’s often used when someone reinvests any interest they gained back into the original investment. So, let take this formula as our benchmark M = P( 1 + i )^n M is the final amount including the principal. P is the principal amount. i is the rate of interest per year. n is the number of years invested. Let's say that I have £100, 000 to invest for 5 years at rate of 15% compound interest. M = 100, 000 (1 + 0.15)^5 = £201 135.719. You can see that my £100, 000 is worth £201,135.719. So, you want to code this algorithm in progamming language like C++, I don't assume you want me to teach you C++. But if you want to learn C++ visit this Tutorial site Ok!!! //Declare some variables to hold these fields int signed * finalPrincipalInterest; int signed * principalAmount; int unsigned short * interest; int signed short *numberOfYears; //Assign the variables data either through dynamic or static data initalization *finalPrincipalInterest = *pow((&principalAmount *(1+&interest)),&numberOfYears); This I hope can help you with your coursework. |

However, you can save, delete, and format your CD-RW/DVD-RW disk. All you need to do like the gurus above me suggested was to buy a CD/DVD writer, hence burner. Remember to buy CD-RW/DVD-RW NOT CD-ROM/DVD-ROM (Read Only Memory). Make sure you install a burner software like nero Finally, when you pop-in your CD-RW/DVD-RW select the option to format as a regular disk. This will set the RW (Read/Write) like your Floppy disk. You can cut and paste, delete, copy and paste like you would in a regular filesystem. |
| Programming / Re: Microsoft Access And Excel by sbucareer(f): 11:06pm On Apr 25, 2008 |
MS-Access and MS-Excel are both used for data storage, retrival and manipulation, hence both are used for database. The real difference is that MS-Access is a RDBMS and MS-Excel is NOT a RDBMS. MS-Excel uses sheet to define its record, whilst MS-Access uses table to define its record. Access is mainly for handling raw or normalized data, whilst Excel is mainly use for data calculation. However, it is possible to transfer data between excel and access with little or no headache |
| Programming / Re: Comparing C++ And C# by sbucareer(f): 6:56pm On Apr 25, 2008 |
C# is another MS strategy to copy Java language. If you don't understand Java, you will not like C#. Overall, it is a web technology. To learn C# you must be thinking of moving into .NET technologies. C# is a very powerful .NET architecture that describes the web and internet programming. C# is scalable and very easy to learn. If you know Java, you already know C#. Albeit, many MS languages is used by .NET i.e. ASP, ASP.NET, C++, to run its .NET infrastructure. I want you to know that MS tried to copy Sun Systems technology at the time when trees looks like ground in the eyes of the monkeys |
| Computers / Re: Microprocessors by sbucareer(f): 11:36am On Apr 21, 2008 |
Just want to share more light to the topic. Micro by definition is an object measured to be smaller than an object that can be scale of focus. Integrated Circuit is a board that contains probably hundreds and millions of microchip, silicon chip or chips, altogether form a miniaturize electronic circuit. Some IC (Integrated Circuit) is dedicated to specific tasks and some are open to generic functions. Example of dedicated IC is watches, calculator, washing machine and toaster. At the other hand the generic IC is computer, mobile phone etc. A microprocessor is a generic IC and can be used for any microprocessing tasks, whilst microcontroller is used for a dedicated task like lunch a missile. I hope this helps. |

Digital circuitry and computers have been the ever greatest man achievement in the last century. Any new advancement will follow this trend. If you understand digital electronics the basis for most technological break through, you will find out that every technology on earth today uses some form of digital encoding signals for communication. However, binary, the method of this communication has begun another big research in the last decade. We are now beginning to understand nanotechnology , biotechnology , these technologies are the core descendant of modern digital circuitry. Furthermore, for us to design any system that could operate at the level of matter on the atomic and molecular scale, that would be the beginning of our end as an advance civilization. Remember that every force there is an opposite and equal force. If we look at the break-through of new technologies, the demographic of our earth is been shaped by it invention. |
| Webmasters / Re: How Do I Build An Intranet by sbucareer(f): 2:45pm On Apr 11, 2008 |
The only visible difference between internet and intranet is the accessibility. However, to setup an intranet you will need to follow the instructions of setting up a webserver. 1. Set up a webserver (Tomcat, XAMP, IIS, APache etc.) 2. Determine communication protocol (Star network, Mesh network or etc.) 3. If you are using Java as a scripting language, configure it to talk to your RDBMS or get someone with RDBMS experience to help your design your information infrastructure. 4. If you are using MS as your platform, configure the HOST file to point to your prefer hostname i.e ice-creamandbradly.com 127.0.0.1 ice-creambradly.com Note, do not modify and other line and no carriage return after your modification. Save the file and close. Make sure that you configure the rest of the workstation to point to the host machine by editing the HOST file and pointing 127.0.0.1 to the host name i.e. 127.0.0.1 168.23.4.1 Save all the workstation HOST file and exit. When you successfully configure your webserver to runn and web application like java or .Net, the rest of the workstation can access the web portal. Note, you do NOT need to register ice-creambradly.com It is a fictitious name for your intranet. I hope this helps. Note HOST file is in c:\windows\system32\host # Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost |

| Investment / Re: Banks With Highest Interest Rate by sbucareer(f): 11:25am On Jun 30, 2007 |
In ideal world all banks within a country or geographical location are all suppose to have the same interest rate. Interest rate are set by the CBN in Nigerian. In the Uk it is set by CBE. Every year banks borrow money from CBN depending on the asset - liabilities + liquid cash. These money are borrowed against the set interest rate. Now, the bank have to pay back the capital + interest. Normally CBN gives very low interest rate like 2% or 2.5% if at any time it goes up to 3% we will have what we call inflation, which is what America is suffering because of the interest rate. Now, the bank obviously would not borrow you money at the same rate they got it from CBN. They would add their cost, profit, expenditures and borrow you like at the rate of 6% 7% or even 8%. If a bank has lower administration and management they could borrow you at a low rate like 6% or less. These rate include insurance against defaults and deaths. So, if you are really looking for low rate banks look at those that are not popular, then again you run the risk of them liquidating or merging with bigger banks and interest rate souring up. The best thing to do is wait till interest rate comes down. If you are a business person and you have some money. The interest rate is really hitting had on some people. People want to sell off. There is low or no demand for buy because of the interest rate. You could approach people that are really struggling for their repayments and make them an offer at a very low and competitive rate. Sell it when the demands goes up and interest rate adjusted. You could wait a little for the equity to rise and make couple of millions. Advise, a bank offering low interest rate has got some hidden agenda, you have to be careful. Most loans anyway are variable, meaning they can't afford a fix rate |
