That is my code Sir!!!!

Your code has a lot of errors and wouldn't work. What I would recommend doing is using a switch structure within either a while loop or do-while loop iteration structure.

Also, why are you attempting to use JOptionpane. That's not via the instructions and is a part of the swing GUI libraries which we won't be doing (not even in the future because Swing is becoming deprecated by Oracle). Instead, we will be using JavaFX in the future for GUI-based assignments. We will only touch on it briefly though because we are trying to solve problems with programming, not trying to make fancy looking GUIs.

With that said, please redo your assignment with the suggestions given thanks!

Hello, that's optional miss. If you want to get into web development then sure, however there is no particular order for learning anything.

Java is a true object-oriented programming language HTML is a markup language and doesn't really teach one the concepts of programming.

Okies!

Your programme is excellent. The only thing you were missing was menu option #5 "exit programme". You implemented it in code, but it is not one of the options to select. I know you just forgot it, so I'll give you an A for this assignment still. Very nicely done!

No problem you did well.

Another assignment for Day 5:

I did not go over how to do random numbers, but I will briefly. Let's assume that you want to create a random number on a dice from 1 to 6, how would you go about doing that?

(int)(Math.random() * 6) + 1); //generate a random number between 1 and 6

I know that you see an int in parenthesis, this is what we call casting in programming when you practically convert a datatype to another datatype. By default, Math.random() method returns a double, so when you place an (int) in front of it, it converts that datatype to an int (we will discuss this a lot more later on the course).

So let's go over the random syntax. If I want to generate a random number between 0 and n, that expression would look something like this in Java:

(int)(Math.random() * n)

if I wanted to generate a random number between 1 and n (where like in the previous example n is any integer) it would look like this:

(int)((Math.random() * n) + 1)

Now for this assignment, I would like for you to create a guessing game that guesses a number between 1 and 100. Once the guess has been achieved, the computer outputs how many guesses it took to get to the random number. This game should not terminate until the user has guessed the correct answer.

Example: see output below to see how game works

Part of being a good Computer scientist is being able to solve difficult problems with a computer, that's what computer science is all about. We have gone over while loops and do while loops as well as the switch case conditional structure. You should try to use those things to solve this problem.

Anything for a beautiful lady,

Well Linux is great for programming because it has built-in tools that Windows does not have (yet) but will certainly have in the future. For one both Linux and Mac (Mac is a UNIX variant) have access to the Bash shell which stands for bourne again script. It allows you to use tools like sed, awk, grep, etc.

Windows will soon have these tools because they are working side by side with U.K. company Canonical (makers of Ubuntu Linux) to incorporate these features used by programmers at the command line. So Windows developers need not worry as this future will probably be available to them sometime between June and August.

Advice, tips, and everything that can improve my codes will be appreciated, thanks Fulaman198.

In the future, when submitting assignments, please submit them in separate posts so that I can better advise you on each one separately. I will start off however with your first submission.

Your code simply won't work, I don't know if you have a compiler to test it out (I haven't tested it), but simply by reading your code, I can assess that your code has a lot of issues. For one, you initialise tries to 0, but in your code, it remains zero because your never increment tries. A lot of your code is truly unnecessary, things can be made much simpler by using a Switch-Case conditional structure (which we went over) within a while or do-while loop structure.

The Switch-Case conditional structure would handle user press events (as you know switch structures work with ints) so if the user presses 1, it does something, if the user presses 2, it does something else if the user presses 5, it exits the program. What i recommend doing is re-reading the section on conditional statements (which if I'm not mistaken should be day 4 in the tutorial). You would want to read the post on the Switch statement and the example(s) I gave.

In regards to your second programme, you don't want to set your while loop to a specific count. The while loop as you remember tests a boolean expression. Kindly think about the code before you write it, remember, what are the requirements for the programme? while the number is not the randomly generated number, then you execute commands within the while block. In addition, your count variable is not rightfully placed. I want you to figure out the first part of the programme though with the while statement. Your randomly generated number syntax is on point and correct. However, the rest of the programme needs work. Please use the critique I have given. Thanks!

No problem miss just install it on VirtualBox to make sure you actually like using Linux first. I find it a very rewarding experience. Ubuntu (Debian-based) Linux is extremely fun.

import.java.util; public class Guesser { public static void main (String[] args) throws java.lang.Exception { double GuessBot=(int) (math.random()*100)+1; string GuessAsker = "'Please Guess a number between 1 and 100'";
} public static void TheGuesser() { system.out.printIn(GuessAsker ); system.out.printIn(GuessBot); }
if(GuessBot==47){ system.out.printIn("You Are Correct"; system.out.printIn(\n) system.out.printIn("YOU WIN" system.exit(0); } else if(GuessBot>47){ system.out.printIn("Too high, try again"; return TheGuesser(); } else if(GuessBot<47){ system.out.printIn("Too low try again"; return TheGuesser();
}

Your randomly generated number syntax is on point and correct. However, the rest of the programme needs work. Please use the critique I have given. Thanks!

Thanks a lot for the advice. About not incrementing tries, I did increment tries in the first assignment. Perhaps the spacing of the codes is too compact that you missed it, it is on the third statement inside the while block. Also, I tried using switch control statement and I have errrors on my compiler, whenever I compiled it, hence, I decided to use if-else-if control statement and it compiled and run without error. However, I will still try using the switch control statement and when it compile well, I will post it here too.
On the second assignment, I compiled it too and it did not show me any error, but since I run the programme, I was not able to guess the correct answer, that is the value entered has not match the randomly generated number till now. So,it seem the problem I may be having is not with the syntax, maybe, logical problem. I will not pretend and act as if I understand what you said about not wanting to initialise my count to 0. If you don't mind could you throw more light on it? I mean why would I initialise tries to 0 in assignment 1 and can not do the same in assignment 2?

About posting my assignment on a separate comment, this is a mistake I will never repeat again. Thanks.
