父方法如果是私有属性（private）就不能再子方法中重写
public class ExtendTest { public static void main(String[] args) {//主方法 new Child().prt(); }}class Child extends Father { public void printF() { System.out.println("F-Child"); } public void printM() { System.out.println("M-Child"); }}class Father { public void printF() { System.out.println("public:Father"); } private void printM() { System.out.println("private:Mother"); } public void prt() { printF(); printM(); }} |
输出：
F-Child
private:Mother
