Learn Java Programming Here Easily

Ride on G! We are damn eager to sit and learn.

God bless ya!!!

I want to learn java database programming but don't know how to
configure my platform to get started.
please I need you to show me how.
Thanks.

What type of java programming tutorials are you able to offer? Applications or Applets? are you a java programmer? is java the only computer language you code in?

Just being inquisitive mate! 

LESSON TWO
     We are going to be looking at Java Applications, Applets, and Database Connectivity.
Before we continue, we are going to talk about various IDE(Integrated Development Environment) to write, compile, and run our java program.
     The best IDE I will recommend is JCreator which can be downloaded from www.jcreator.com.
   The Advantage of this software is to enable us to feel the fonts, and colours the text gives us. After you have installed the JCreator software. The we can Continue our program,

@azpunpin
This IDE is not free , where do you get your's do you pay for it ,because i need one.

LESSON 3

Myfirst Java Program,
Open the text editor in your IDE. Write the following code,
========================================================
public class myFirstProg {
    public static void main(String args[]) {
       system.out.println("Welcome to Java World!, \nThis is my first program);
   }
}
=========================================================
We are using JCreator software(if u dont have one already, download it at www.jcreator.com) to run this program, save your text as myFirstProg.java
press F5,
wait for response, that's all.
----------------------------------------------------
Explanation of the program:
line 1: public class myFirstProg {
this is class definition. the first thing in Java program is to define your class and the name of your class must be the same as the name of your program(Here the class name is myFirstProg which must be the same as the name of your text file)
Also our class is define as public(you will know this later on)
A right curly { bracket is used to open the program,
To be Continued,

Just a small addition regarding an IDE. I normally would not recommend a beginner use and IDE ( I always suggest textpad). But, if you cannot get a hold of the already suggested one, eclipse is another free IDE that is quite good.

Just google for it. You can also get it from other mirror sites.

http://www.eclipse.org/downloads/

That is a left Brace (Curly Bracket) and that a "{" is used to open the program in java is absurd. what is the  "{" after the main method doing ?

Good intentions. But there is really no point re-inventing the wheel. Also, am an open source advocate, the part of people having to pay for JCreator makes me frown. There are so many free, arguably better IDEs one that easily comes to mind is Netbeans 6.5 IDE from www.netbeans.org.

And like a friend said earlier, what does a beginner need an IDE for? It just makes matters complicated and bogous. So just download Textpad for free or if your on Linux try using vim editor or notepad for windows.

I downloaded the Jcreator free of charge from their website. I even downloaded the Pro Version.

I need help, i was learning more on java and i reach the part import java.util.Scanner

I tried to use the code to sum up 2 integer but i keep having problem when compiling it with both Jcreator and Command Prompt.

Anybody to fix it up for me Plzzzzzzzz!!

In java it doesnt matter the way you declare an array , it can be "String [] args" or "String args[]", they're both the same. However in c++ it does matters. You only declare arrays this way : " string s [].

Thanks House.
I've many issues to clear,
but firstly Im very sorry that I didn't post since thursday,

1. About the IDE,  I said IDE is free and can be downloaded free of charge. But in case of those who are asking for the licence I ask them to get it from the site or mail me.Clear(ade2kay)

2. About using textpad, there is no compulsion in using IDE You can use textpad but using any IDE will make your program look nicely, and you can run your program by just clicking a button.(Note any IDE can be used, just go to google and write "free java IDE")

3. Thanks azpumpin it was a mistake the line is ("Welcome to Java World!, \nThis is my first program");

4. { is used to open the program and also is also used to open any method you use in your program. the method used is main method so for main method you will need to open { for it

5. As for now Declaring any class or method public should be accepted until Chapter that described (Method--private,public,protected)

6. importing a scanner class should be done when writting from a keyboard, to a file etc
this is how it should be done
 
              import java.util.*;
              import java.io.*;

Scanner class is in the java utility package so when you need it just iport the whole package by ( import java.util.*

7. summing up two integers

     
       
       import java.util.*;
       import java.io.*;

  public class Addition {
     public static void main(String args[])
   // can also be written as String []args, you will understand better when doing Array.
  {
   Scanner kb = new Scanner(System.in); // make Scanner object kb
   int firstValue, secondValue; // Declaring variable
   int sum;
   System.out.print("Enter the first value : ");
   firstValue = kb.nextInt;
   System.out.print("Enter the second value : ");
   secondValue = kb.nextInt;
 
   sum = firstValue + secondValue;
   System.out.println("The result is "+sum);
   }
}
That is it,
one house,

Which JDK version are you using? The Scanner class is part of JDK 1.5 and up.

Did you have a previous version of the JDK, if so may be you are still pointing to that one. To verify that you are actually getting to the Scanner class, try this on the import and see if you get an error.

import java.util.Scanner;
