多态之静态方法和非静态方法

class Super {static void greeting() {System.out.println("greetingSuper");}}class Sub extends Super {static void greeting() {System.out.println("greetingSub");}}public class Test {public static void main(String[] args) {Sub s2 = new Sub();s2.greeting();Super s3 = new Sub();s3.greeting();}}

打印结果是greetingSub
                    greetingSuper
