看程序写结果:先判断有没有问题，如果没有，写出结果class Fu {public void show() {System.out.println("fu show");}}class Zi extends Fu {public void show() {System.out.println("zi show");}public void method() {System.out.println("zi method");}}class DuoTaiTest {public static void main(String[] args) {Fu f = new Zi();f.method();f.show();}}
