Question

How to create a custom Exception?

Answer 1

• CustomException class is the custom exception class this class is extending Exception class.
• Create one local variable message to store the exception message locally in the class object.
• We are passing a string argument to the constructor of the custom exception object. The constructor set the argument string to the private string message.
• toString() method is used to print out the exception message.
• We are simply throwing a CustomException using one try-catch block in the main method and observe how the string is passed while creating a custom exception. Inside the catch block, we are printing out the message.
