Question

What will the following code print when run? 

public class Main {
   static String j = "";

   public static void method(int i) {
      try {//ww w.  jav a2 s .  c o  m
         if (i == 2) {
            throw new Exception();
         }
         j += "1";
      } catch (Exception e) {
         j += "2";
         return;
      } finally {
         j += "3";
      }
      j += "4";
   }

   public static void main(String args[]) {
      method(1);
      method(2);
      System.out.println(j);
   }
}

Select 1 option

  • A. 13432
  • B. 13423
  • C. 14324
  • D. 12434
  • E. 12342


Correct Option is  : B

Note

in method( 1) : i is not 2 so, j gets "1" then finally is executed which makes j = "13" and then the last statement (j +=4) is executed which makes j = "134".

in method(2) : i is 2, so it goes in the if block which throws an exception.

So none of the statements of try block are executed and control goes to catch which makes j = "1342", then finally makes j = "13423" and the control is returned.

The last statement (j+=4) is not executed as there was an exception thrown in the try block, which cause the control to go to the catch block, which in turn has a return.
