Java | Exception Handling | Question 1

Predict the output of following Java program

class Main {
   public static void main(String args[]) {
      try {
         throw 10;
      }
      catch(int e) {
         System.out.println("Got the  Exception " + e);
      }
  }
}

(A) Got the Exception 10
(B) Got the Exception 0
(C) Compiler Error

Answer: (C)
Explanation: In Java only throwable objects (Throwable objects are instances of any subclass of the Throwable class) can be thrown as exception. So basic data type cannot be thrown at all.

Following are errors in the above program

Main.java:4: error: incompatible types
         throw 10;
               ^
  required: Throwable
  found:    int
Main.java:6: error: unexpected type
      catch(int e) {
            ^
  required: class
  found:    int
2 errors
