Exception in Java With Examples

Aim of this program:

To Use inheritance to create an exception super class called Exception A and exception sub class Exception B and Exception C, where Exception B inherits from Exception A and Exception C inherits from Exception B. Write a java program to demonstrate that the catch block for type Exception A catches exception of type Exception B and Exception C

Exception in java small Description before coding

Create a class ExceptionA which extends Exception class. Create ExceptionB and ExceptionC classes, such that ExceptionB inherits from ExceptionA and ExceptionC inherits from ExceptionB. The catch block for type ExceptionA

catches exception of type ExceptionB and ExceptionC
