java设计模式 之 抽象工厂模式

java设计模式 之 抽象工厂模式

抽象工厂模式：解决了工厂模式的弊端，当新加一个功能的时候，不会影响之前的代码。

接口 IMobile 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public interface IMobile {
public void printName();
}

实现类 IPhoneMobile 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public class IPhoneMobile implements IMobile {

@Override
public void printName() {
System.out.println("我是一个iPhone手机!");
}

}

实现类 SamsungMobile 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public class SamsungMobile implements IMobile {

@Override
public void printName() {
System.out.println("我是一个三星手机!");
}
}

接口 IFactory 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public interface IFactory {
public IMobile produce();
}

IPhone手机工场类 IPhoneFactory 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public class IPhoneFactory implements IFactory {

@Override
public IMobile produce() {
return new IPhoneMobile();
}
}

三星手机工场类 SamsungFactory 代码如下：

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package Factory;

/**
*
* @author dev
*/
public class SamsungMobile implements IMobile {

@Override
public void printName() {
System.out.println("我是一个三星手机!");
}
}

最后，main 函数如下：

public static void main(String[] args) {
// TODO code application logic here
IFactory factory = new IPhoneFactory();
IMobile iphone = factory.produce();
iphone.printName();
}

运行效果如下：
