  • Question
  • What will be the output of the program?
    int I = 0;
    label:
        if (I < 2) {
        System.out.print("I is " + I);
        I++;
        continue label;
    }
    


  • Options
  • A. I is 0
  • B. I is 0 I is 1
  • C. Compilation fails.
  • D. None of the above

  • Correct Answer
  • Compilation fails. 

    Explanation
    The code will not compile because a continue statement can only occur in a looping construct. If this syntax were legal, the combination of the continue and the if statements would create a kludgey kind of loop, but the compiler will force you to write cleaner code than this.
