You may need to compile the GameLauncher.java file.

That fixed my problem I thank you guys kindly, I'm amazed by how fast you guys always help out!

I'll just continue to annoy the hell out of you guys till I know enough java myself to help others

Btw is it possible to copy text from the cmd to any other application, as I'm trying to by selecting the text I want to copy and using Ctrl+c and Ctrl+v but no success

Thank you for replying, I was executing the GuessGame class, and figured oh yeah kinda stupid to execute the class that doesn't have a main function..

However I would like to

But I got the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: GameLauncher caused by: java.lang.ClassNotFoundException: GameLauncher at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Could not find the main class: GameLauncher. Program wil exit.

GuessGame.class:
public class GuessGame{ Player p1; Player p2; Player p3; public void startGame(){ p1 = new Player(); p2 = new Player(); p3 = new Player(); int guessp1 = 0; int guessp2 = 0; int guessp3 = 0; boolean p1isRight = false; boolean p2isRight = false; boolean p3isRight = false; int targetNumber = (int) (Math.random() * 10); System.out.println("I'm thinking of a number between 0 and 9..."); while(true) { System.out.println("Number to guess is " + targetNumber); p1.guess(); p2.guess(); p3.guess(); guessp1 = p1.number; System.out.println("Player one guessed " + guessp1); guessp2 = p2.number; System.out.println("Player two guessed " + guessp2); guessp3 = p3.number; System.out.println("Player three guessed " + guessp3); if (guessp1 == targetNumber) { p1isRight = true; } if (guessp2 == targetNumber) { p2isRight = true; } if (guessp3 == targetNumber){ p3isRight = true; } if (p1isRight || p2isRight || p3isRight){ System.out.println("We have a winner!"); System.out.println("Player one got it right? " +p1isRight); System.out.println("Player two got it right? " +p2isRight); System.out.println("Player three got it right? " +p3isRight); System.out.println("Game is over."); break; //game over, so break the loop } else{ //We must keep going if nobody got it right! System.out.println("Players will have to try again."); }//end if/else }//end loop }//end method }//end class
Player:
public class Player.class { int number = 0; //where the guess goes public void guess(){ number = (int) (Math.random() * 10); System.out.println("I'm guessing " + number); } }
GameLauncher.class
public class GameLauncher { public static void main (String[] args) { GuessGame game = new GuessGame(); game.startGame(); } }

What am I doing wrong? I read somewhere that you need to use main (String[] args) But I'm already doing that, and the code is like this in my book (Head First Java)

Using JDK 1.6.0 update 12 btw

In other words it compiles just fine but won't run.

Or you can just hit language and then select java

Notepad++ is the most awesome text editor out there imo :P

As I don't see an edit button

I would also like to thank you for your quick replies!

Edit: and after posting this message it appeared

Oh, that fixed my problems! I thank you kindly

And thanks for the welcome

Hey there, I just got "Head First Java (2nd edition)"

And ran into some trouble with the examples on page 12 & 13

It compiles just fine, but when I try to run the class file I get the following error:
C:\Program Files\Java\jdk1.6.0_12\bin>java DooBee.class Exception in thread "main" java.lang.NoClassDefFoundError: DooBee/class Caused by: java.lang.ClassNotFoundException: DooBee.class at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Could not find the main class: DooBee.class. Program will exit.
And this is the actual code:
public class DooBee{ public static void main (String[] args){ int x = 1; while(x<3){ System.out.println("Doo"); System.out.println("Bee"); x++; } if(x == 3){ System.out.println("Do"); } } }

What am I doing wrong?

Btw I'm using notepad++ to write my code, just the cmd from my windows xp sp3 for compiling and running the .class from the .java file

So I compile (which goes just fine) Hence I think the problem might be somewhere in my JDK folder
I can't run, I was able to run the first example though..

Any help is greatly appreciated

Kudos,
