java設計模式 之 抽象工廠模式
抽象工廠模式：解決了工廠模式的弊端，當新加一個功能的時候，不會影響之前的代碼。
- 接口 IMobile 代碼如下：
/*
* 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();
}
- 實現類 IPhoneMobile 代碼如下：
/*
* 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("我是一個iPhone手機!");
}
}
- 實現類 SamsungMobile 代碼如下：
/*
* 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("我是一個三星手機!");
}
}
- 接口 IFactory 代碼如下：
/*
* 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手機工場類 IPhoneFactory 代碼如下：
/*
* 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();
}
}
- 三星手機工場類 SamsungFactory 代碼如下：
/*
* 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("我是一個三星手機!");
}
}
- 最後，main 函數如下：
public static void main(String[] args) {
// TODO code application logic here
IFactory factory = new IPhoneFactory();
IMobile iphone = factory.produce();
iphone.printName();
}- 運行效果如下：
