Labelled continue

[Venkat Valluru]

hi,
What will be the output when you compile and execute the following program.
public class Base{

private void test() {

one:
for (int i = 0; i < 3; i ++) {

two:
for(int j = 0; j < 3; j++){

if (i == 2)
continue two;

if ( j == 2)
continue one;

System.out.println("Values : " + i + "," + j);
}
}
}

static public void main(String[] a) {
new Base().test();
}

}
Select all valid answers
a) Values : 0,0
b) Values : 0,1
c) Values : 1,0
d) Values : 1,1
e) Values : 2,0
f) Values : 2,1
Here the correct answers given are a,b,c,d
According to me f should also be the correct answer
as when i == 2 then there is continue two:
so j=0 iteration should not be executed but j=1 should be executed.so 2,1 should also come .
but i ran this code and f) answer is not coming.
Can somebody enlighten me on this??

anonymous (?),

   public class Base
   {
      private void test() {
      one:
         for (int i = 0; i < 3; i ++) // loop one
         {
         two:            
            for(int j = 0; j < 3; j++)  // loop two
            {
               if (i == 2) // condition one
                  continue two;
               if ( j == 2) // condition two
                  continue one;
               System.out.println("Values : " + i + "," + j);      
            }   
         }
      }
   
      static public void main(String[] a) 
      {
         new Base().test();
      }  
   }

Let's trace the program:
Enter loop one
When i = 0,
Enter loop two.
When j = 0, both condition one and two are false. So, print i = 0 and j = 0.
When j = 1, both condition one and two are false. So, print i = 0, and j = 1.
When j = 2, condition one is false, condtion two is true. So, go back to loop one, without printing the values.
When i = 1
Enter loop two.
When j = 0, both condtion one and two are false. So, print i = 1 and j = 0.
When j = 1, both condtion one and two are false. So, print i = 1 and j = 1.
When j = 2, condtion one is false, condtion two is true. So, go back to loop one, without printing the values.
When i = 2,
Enter loop two.
Throughout the loop i will be two and hence condtion one will evaluate to true all the time and hence, it won't come the printing statement.
So, the output will be
0,0
0,1
1,0
1,1.
So, a,b,c and d are the correct answers.
