Java设计模式之适配器模式

适配器模式：

1，类适配器模式

源角色(Adaptee):

package com.classadpter;
public class Adaptee {
public void code(){
System.out.println("能写代码");
}
}

目标抽象角色(Target):

package com.classadpter;
public interface Target {
public void code();
public void pm();
}

适配器角色(Adapter)

package com.classadpter;
//Adpter：就是继承Target,继承Adaptee
public class Adapter extends Adaptee implements Target {
//这里这个IT民工即能写代码，也想能做产品,话说好多coder都喜欢这么yy来着
@Override
public void pm() {
// TODO Auto-generated method stub
System.out.println("还能做产品");
}


public void work(){
this.code();
this.pm();
}

public static void main(String[] args) {

Adapter adapter = new Adapter();
adapter.work();

}

}

test result:

能写代码
还能做产品

2，对象适配器模式

源角色(Adaptee):

package com.objectadapter;
public class Adaptee {
public void code(){
System.out.println("能写代码");
}
}

目标抽象角色(Target):

package com.objectadapter;
public interface Target {
public void code();
public void pm();
}

package com.objectadapter;

//Adpter：就是继承Target,继承Adaptee
public class Adapter implements Target {
public Adaptee adaptee ;
//这里这个IT民工即能写代码，也能做产品,话说好多coder都喜欢这么yy来着
public Adapter(Adaptee adaptee){
this.adaptee = adaptee;
}

public void code() {
// TODO Auto-generated method stub
this.adaptee.code();
}

public void pm() {
System.out.println("我还能做产品");
}

public void work(){
this.code();
this.pm();
}

public static void main(String[] args) {
Adaptee adaptee = new Adaptee();
Adapter adapter = new Adapter(adaptee);
adapter.work();

}

}
