Which is an example of a naming class?

How to raise exception of user defined type?
To raise exception of user-defined type, we need to create an object to his exception class and throw it using throw clause, as: MyException me = new MyException(“Exception details”); throw me; The following program illustrates how to create own exception class MyException.
