适配器模式

Target（目标接口）：所要转换的所期待的接口

Adaptee（源角色）：需要适配的接口

Adapter （适配器）：将源接口适配成目标接口，继承源接口，实现目标接口

 

Adaptee

package design.pattern.adapter;

public interface Adaptee {
    public void adapteeWorkType();
}

Target

package design.pattern.adapter;

public interface Target {
    public void targetWorkType();
}

Adapter

package design.pattern.adapter;

public class Adapter implements Target{

    private Adaptee adaptee;
    public Adapter(Adaptee adaptee) {
        this.adaptee = adaptee;
    }
    @Override
    public void targetWorkType() {
        adaptee.adapteeWorkType();
    }

}

ConcreteAdaptee

package design.pattern.adapter;

public class ConcreteAdaptee implements Adaptee{

    @Override
    public void adapteeWorkType() {
        System.out.println("adapteeWork");
    }

}

 

Client

package design.pattern.adapter;

public class Client {
    public static void main(String[] args) {
        new Adapter(new ConcreteAdaptee()).targetWorkType();
    }
}
