这里写图片描述

Moveable.java:

public interface Moveable{    void Run();}

VehicleFactory.java:

public abstract class VehicleFactory{    abstract Moveable create();}

car.java:

public class Car implements Moveable{    private static Car car=new Car();    public Car()    {    }    public void Run()    {        System.out.println("冒着烟奔跑中car。。。。。。");    }    /**     * 静态工厂方法     * @return     */    public static Car getInstance()    {        return car;    }}

carFactory.java;

public class CarFactory extends VehicleFactory{    @Override    Moveable create()    {        return new Car();    }}

Plane.java:

public class Plane implements Moveable{    @Override    public void Run()    {        System.out.println("扇着翅膀前进中plane......");    }}

PlaneFactory.java:

public class PlaneFactory extends VehicleFactory{    @Override    Moveable create()    {        return new Plane();    }}

Test.java;

package com.bjsxt.dp.factory;public class Test{    public static void main(String[] args)    {//      Car car=Car.getInstance();//      Car c2=Car.getInstance();//      if(car==c2)//      {//          System.out.println("same car");//      }//      car.Run();        VehicleFactory factory=new BoomFactory();//new PlaneFactory()//new CarFactory();        Moveable m=factory.create();        m.Run();    }}
