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
Source code |Types of exception in java
class ExceptionA extends Exception
class ExceptionB extends ExceptionA
public static void getExceptionB() throws Exception
throw new ExceptionB("Exception B");
class ExceptionC extends ExceptionB
public static void getExceptionC() throws Exception
throw new ExceptionC("ExceptionC");
public static void main(String ar) throws Exception
