Write a Java program to create and throw custom exceptions.

// class that uses custom exception InvalidAgeException
public class TestCustomException1
{
// method to check the age
static void validate (int age) throws InvalidAgeException{
if(age < 18){
// throw an object of user defined exception
throw new InvalidAgeException("age is not valid to vote");
}
else {
System.out.println("welcome to vote");
}
}
// main method
public static void main(String args[])
{
try
{
// calling the method
validate(13);
}
catch (InvalidAgeException ex)
{
System.out.println("Caught the exception");

// printing the message from InvalidAgeException object
System.out.println("Exception occured: " + ex);
}
System.out.println("rest of the code…");
}
}
