Java 我想检查我的输出是否正确。还有，有关此“getClass（）”方法的更多详细信息

我刚开始学习Java，遇到了这个问题。我不确定我的输出是否正确。我还想在此上下文中了解更多关于“getClass”方法的详细信息，因为“Orc”和“Unicorn”不是从同一个类继承的

我的输出是：

神话 嘶叫 不 Raaa！ 对吗

最后一个问题:

子类的对象是父类的实例吗？

您的代码工作正常，输出也正确

最后一个问题:

子类的对象是父类的实例吗

为了弄清楚上面的问题，你需要学习继承的概念。 请考虑以下代码。我已在评论中解释

    class Super {
    public void test() {
        System.out.println("From Super Class TestMethod");
    }
}

class Sub extends Super {
    public void subTest() {
        System.out.println("From the Sub Class Test ");
    }
}

public class SubSuperCheck {

    public static void main(String[] args) {
        Sub s = new Sub();// when JVM find this, it will create the memory for
                            // the
                            // two methods test() from Super class and subTest()
                            // from Sub Class
                            // if the reference(Sub s) is also the Sub then we
                            // can access the two methods(test() and subTest())

        System.out.println(s.getClass());// getClass() method of Object class
                                            // will return the the class name
