So either you are not showing us the calling class or you simply forgot to add a main method. A possible way to generate output would be:

public static void main(String[] args) {
    new PersonType("Cy", "Car").print();
}

CodePudding user response：

try

    public static void main(String[] args) {
        new PersonType("Cy", "Car").print();
    }
