design_model（5）adapter

1.适配器模式

将一个接口转换为我们所需要的的接口

2.实例

 

public  interface Adapter {
	public abstract void  test() ;
}

public class Adaptee  implements  Adapter{
	@Override
	public void  test() {
		
	}
}

public  interface  Target {
   public  abstract void  handler();
}

public class TargetImp   implements  Target{
	private  Adapter adapter;
	@Override
	public void handler() {
		adapter.test();
	}
	public TargetImp(Adapter adapter) {
		super();
		this.adapter = adapter;
	}
}

public class Client {
	  public static void main(String[] args) {
		 Adaptee adaptee = new Adaptee();
		 TargetImp targetImp = new TargetImp(adaptee);
		 targetImp.handler();
	  }
}
