I am doing this exercise in Java and when I try to run it, it says no Class found and I have 2 errors.   Any help would greatly be appreciated.

package loadeddie;
import java.util.Random;

public class LoadedDie{

   public LoadedDie(int pctChance)
{    
        chanceForSix = pctChance;
        Random generator = new Random();
}  
     public int rollDie()
     {        
         int chanceForOthers;
         int randNum;
         
         chanceForOthers = (100 - chanceForSix)/5;
         randNum = generator.nextInt(100);
       
        If (randNum < chanceForSix){
             
           return 6;}
        else {
           
           
            return(randNum - chanceForSix)/ chanceForOthers;}
       
     }
   
        private int chanceForSix;
        private Random generator;
}

How are you trying to run this?  There is no static main method, so can't execute directly.  You will have to instantiate from another object or create a main method.

Hope that helps, please post back if you need more assistance after giving that a try.

Regards,
Kevin

Sorry, I am Lost.  

Running in  NetBeans IDE 6.1.

This is what the result at the bottom says:

init:
deps-jar:
Compiling 1 source file to C:\Documents and Settings\Angela\My Documents\NetBeansProjects\LoadedDie\build\classes
C:\Documents and Settings\Angela\My Documents\NetBeansProjects\LoadedDie\src\loadeddie\LoadedDie.java:19: ';' expected
         If (randNum < chanceForSix){            
C:\Documents and Settings\Angela\My Documents\NetBeansProjects\LoadedDie\src\loadeddie\LoadedDie.java:21: 'else' without 'if'
        else {                      
2 errors
BUILD FAILED (total time: 0 seconds)

Well, java is case sensitive, so If is not equivalent to if.  
Change this: If (randNum < chanceForSix)
To this: if (randNum < chanceForSix)

That fix the compile errors
init:
deps-jar:
Compiling 1 source file to C:\Documents and Settings\Angela\My Documents\NetBeansProjects\LoadedDie\build\classes
compile-single:
BUILD SUCCESSFUL (total time: 0 seconds)

Can you explain what "<No main classes found>" means?

See my first comment as I thought that was were you were at with errors. :) As the error suggests you don't have a main method.

If you need more / deeper explaination you can refer to http://java.sun.com/docs/books/tutorial/ or post back after trying to implement based on my feedback.

I found this piece of code, Can I change this to fit my code?


package loadeddie;
import java.util.Random;

public class LoadedDieTester {
public static void main(String[] args)
    {
        Random myDie = new Random ();
System.out.println("The Result of the toss is " + (myDie.nextInt(6)+1));

    }
}

Think of this in object oriented terms.  You have created a dice object that is now sitting on the table.  It will never roll unless you have a Player object or something that rolls it.

Yes, you now have a Player object.

Now that player object needs to know about your Die object to roll it.  Instead of instantiating "Random myDie = new Random();" try instantiating your class LoadedDie then call your roll method.

Hopefully that helps.

And hopefully being clear enough.
