什麼是多態

簡單的來說就是具有多種形態的能力的特徵

package ten;public interface Day1 {public void ring();}package ten;public class Day2 extends Day3 implements Day4,Day1 {@Overridepublic void openlock() {// TODO Auto-generated method stubSystem.out.println("...............");}@Overridepublic void getlock() {// TODO Auto-generated method stubSystem.out.println("...............");}@Overridepublic void open() {// TODO Auto-generated method stubSystem.out.println("...............");}@Overridepublic void close() {// TODO Auto-generated method stubSystem.out.println("...............");}@Overridepublic void ring() {// TODO Auto-generated method stubSystem.out.println("..........25646+.....");}}package ten;public abstract class Day3 {//開門public abstract void open ();//關門public abstract void close();}package ten;public interface  Day4 {//開鎖public void openlock();//上鎖public void getlock();}package ten;public class luge {public static void main(String[] args) {// TODO Auto-generated method stubDay2 d = new Day2();d.getlock();d.open();d.openlock();d.close();d.ring();}}
