Flow Control.......

[sonir shah]

class LoopTest 
{ 
public static void main(String args[]) 
{ 
int counter = 0; 
outer: for(int i = 0; i < 3; i++)
                   middle: for(int j = 0; j < 3; j++) 
                        inner: for(int k = 0; k < 3; k++)
       { 
                             if(k-j>0) break middle; 
                             counter++;
                                    } 
System.out.println(counter); 
}
}

Options :
1)2
2)3
3)6
4)7
5)9
I tried running the code and got the output as 3.
Can any one make me understand the flow of the code?

Hi Sonir :
write it this way
i=0;j=0;k=0 counter will be 0(1)
i=0;j=0;k=1 break's out
i=1;j=0;k=0 counter will be 1(2)
i=1;j=0;k=1 break's out
i=1;j=0;k=0 counter will be 2(3)
i=1;j=0;k=1 break's out
i=2;j=0;k=0 counter will be 3(4)
i=2;j=0;k=1 break's out
So the answer 3 will be printed.
Hope this helps

first ......i=0 j=0 k=0, counter =1
second ........... k=1, break middle and enter outer
third ...... i=1 j=0 k=0 counter =2
fourth ........... k=1 break middle and enter outer
fifth i=2 j=0 k=0 counter =3
......... k=1 break middle and enter outer
and it stops as i cannot be incremented further.
hope this helps....
