MOCK TEST-2, Q:-46 : qid: enthuware.ocajp.i.v8.2.1010

Code: Select all

public class TestClass{
  public static void main(String[] args){
     Fo : for(int i = 0; i< 10; i++){
        for (int j = 0; j< 10; j++){
             if ( i+ j > 10 )  break fo;
        }
        System.out.println( "hello");
     }
  }
}

why hello is printed only twice and breaks out of the loop while i debug this on eclipse and suddenly after i=2 it breaks out of the loop, and j can still go till 9th iteration,

please explain in detail its very confusing?

[admin]

When i is 0 or 1, j can go from 0 to 9 without breaking because i+j cannot be > 10 in these cases. This means hello will be printed once when 1 is 0 and second when i is 1. But when i becomes 2, as soon as j becomes 9, break fo; will be executed breaking the outer loop. Hence, the print statement will not be executed.

Btw, please put question id in the subject line so that this topic will be associated with that question.

so that means it will print the statement only when J loop will finish all its iterations and if it doesnt then it will break out of the loop and the statement. is it?

[admin]

Yes, break fo; breaks the outer loop.
