The throws Keyword in Java

Use throws in method signatures to indicate that your method might throw an exception, requiring handling by the caller.

Source Code

public static void checkAge(int age) throws ArithmeticException {
    if (age < 18) {
        throw new ArithmeticException("Access denied - You must be at least 18 years old.");
    } else {
        System.out.println("Access granted");
    }
}
