Defining Custom Exception Class

In this problem, you will create a program that defines a custom exception class AgeException extending Exception, and throws it from an age validation method.

Learning Objective: Understand how to define custom exception classes by extending Exception and throw exceptions with throw

Overview

Java allows defining custom exception classes to represent application-specific error conditions. Create a custom exception by extending the Exception class.

Specifications

AgeException class (AgeException.java)

• Extends Exception
• Constructor: AgeException(String message)
  • Pass message to parent class via super(message)

Main class (Main.java)

• static void validateAge(int age) throws AgeException
  • If age is less than 0 or greater than 150, throw AgeException
  • Message: "Age X is out of valid range (0-150)" (X is the argument value)
  • If valid: complete normally without throwing
• Include a main method (for compilation)

Test Method

Each test case calls Main.validateAge(int) directly and verifies:

• Valid ages (e.g., 25, 100) do not throw an exception
• Invalid ages (e.g., -5, 200) throw AgeException with the correct message
