Program 1

class UnderAgeException extends Exception 
{
    public UnderAgeException(String message)
 {
        super(message);
    }
}

public class TestException1
 {

    public static void validateAge(int age) throws UnderAgeException 
{
        if (age < 5) {
            throw new UnderAgeException("Age must be 5 or above to join the Kathak course.");
        }
        System.out.println("Admission successful!");
    }

    public static void main(String[] args) 
{
        try {
            validateAge(9);
        } 
         catch (UnderAgeException e) 
        {
            System.out.println("Exception caught: " + e.getMessage());
        }
    }
}
        //  throw new UAE("by five")
