The source code to demonstrate the finally block in exception handling is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.
Output:
Explanation:
In the above program, we created a class ExceptionDemo that contains two methods PrintHello() and Main(). The PrintHello() message will print "Hello World" on the console screen.
In the Main() method, we created an object E in the "try" block. Then we assigned the value "null" to the reference E and then call PrintHello() method with a null reference. That's why the NullReferenceException exception gets generated and caught by the "catch" block that will print the exception message on the console screen and then the "finally" block gets called and print "Finally block executed" message on the console screen.
