A Simple Example of finally block in Java

class Test2
{
   public static void main(String args[]) {
      try{
int num=121/0;
System.out.println(num);
      }
      catch(ArithmeticException e){
         System.out.println("Number should not be divided by zero");
      }
      /* Finally block will always execute
       * even if there is no exception in try block
       */
      finally{
System.out.println("This is finally block");
      }
      System.out.println("Out of try-catch-finally");
   } 
}




Output :-


Number should not be divided by zero
This is finally block
Out of try-catch-finally

Here you can observe that the exception occurred in try block which has been handled in catch block, after that finally block got executed.

A finally block must be connected with a try block, you cannot use finally without a try block. You must place those statements in this block that must be executed always.
