Java OCA OCP Practice Question 1536

Question

What will be the result of attempting to compile and run the following program? 

public class Main{
   public static void main (String args []){
      int i = 0;
      for  (i=1 ;  i<5  ; i++) continue;  // (1)
      for  (i=0 ;       ; i++) break;     // (2)
      for  (    ; i<5?false:true ;    );  // (3)
    }
}

Select 1 option

  • A. The code will compile without error and will terminate without problems when run.
  • B. The code will fail to compile, since the continue can't be used this way.
  • C. The code will fail to compile, since the break can't be used this way
  • D. The code will fail to compile, since the for statement in the line 2 is invalid.
  • E. The code will compile without error but will never terminate.


Correct Option is  : A

Note

A continue statement can occur in and only in a for, while or do-while loop.

A continue statement means: Forget about the rest of the statements in the loop and start the next iteration.

So, for (i=1 ; i<5 ; i++) continue; just increments the value of i up to 5 because of i++.

for (i=0 ;___; i++) break; iterates only once because of the break so the value of i becomes 0.

for(___; i<5?false:true ; ); never iterates because i is less than 5 (it is 0 because of //2) and the condition expression is false!

At the end of the code, the value of i is 0.
