Help With Bluej

[Shahr]

Hi! my name is Shahr and im using bluej, For Some Reason My Code Isnt Working Properly
import java.util.Scanner;
public class Katan
{
public static void main(String[]args)
{
Scanner in=new Scanner(System.in);
int n,i,math=1;
System.out.println("Enter N");
n=in.nextInt();
for(i=0;i<=1;i++)
{
if(n<10)
{
math=math*n;
System.out.println("Enter N");
n=in.nextInt();
}
else
{
System.out.println("Enter N");
n=in.nextInt();
}
}
System.out.println(math);
}
}
Here Is My Code And Its Supposedly Needs To Print Out Enter N Once And For Some Reason It Prints It 3 Times And Gives The User 3 Time To Enter The Number Again
import java.util.Random;
public class SheshBesh
{
public static void main(String[]args)
{
Random in=new Random();
int Cube1,Cube2,Benim;
Cube1=in.nextInt(6)+1;
Cube2=in.nextInt(6)+1;
while(Cube1!= 5&&Cube2!=6)
{
if(Cube1==6&&Cube2==5)
{
Benim=Cube2;
Cube2=Cube1;
Cube1=Benim;
}
else
{
System.out.println("Cube1= " + Cube1);
System.out.println("Cube2= " + Cube2);
}
Cube1=in.nextInt(6)+1;
Cube2=in.nextInt(6)+1;
}
System.out.println("שש בש");
System.out.println("Cube1= " + Cube1);
System.out.println("Cube2= " + Cube2);
}
}

This Is Another Example Of It Not Working Well. This Code Is Simulating A Cube And Pasting Its Results Until The Cubes Are Either 6 5 Or 5 6, And For Some Reason It Doesnt Count The && And When One Of The Cubes Equals 6 or 5 It Is Ending The Loop, Is It Me? Or Bluej 😛

First, use code tags!

import java.util.Scanner;
public class Katan
{
    public static void main(String[]args)
    {
        Scanner in=new Scanner(System.in);
        int n,i,math=1;
        System.out.println("Enter N");
        n=in.nextInt();
        for(i=0;i<=1;i++)
        {
            if(n<10)
            {
                math=math*n;
                System.out.println("Enter N");
                n=in.nextInt();
            }
            else
            {
                System.out.println("Enter N");
                n=in.nextInt();
            }
        }
        System.out.println(math);
    }
}

I'm pretty sure your bug is in the first section there. in.nextInt() asks for a value every time it's called. Can you step through the code and see how it's called three times? If not, BlueJ should have a debugger that can step through the code for you from the point where you set a breakpoint.

Another option might be

Spoiler: an older debugging technique

to change your System.out.println values so each one is unique so you know where calls are being made from.

But that might be giving away too much. 😉
