只使用一个适配器_只有一个adapter-优快云博客

本文介绍了一种软件设计模式——适配器模式，并通过具体的Java代码实现展示了如何使用该模式来连接不同的接口。适配器模式使得原本不兼容的接口能够协同工作，提高了系统的灵活性。

代码如下

package com.gqc.adapters;

public interface IWorkerAdapters {
	String work(Object worker);
}

package com.gqc.adapters.impl;

import com.gqc.adapters.IWorkerAdapters;
import com.gqc.worker.ICooker;
import com.gqc.worker.IProgrammer;

//适配器类
public class WorkerAdapter implements IWorkerAdapters {

	@Override
	public String work(Object worker) {
		String workContent="";
		
		//如果传来的对象是厨师 则调用其cook方法
		if(worker instanceof ICooker){
			workContent=((ICooker)worker).cook();
		}
		//如果是程序员 则调用program方法
		if(worker instanceof IProgrammer){
			workContent=((IProgrammer)worker).program();
		}
		return workContent;
	}

}

package com.gqc.test;

import com.gqc.adapters.IWorkerAdapters;
import com.gqc.adapters.impl.WorkerAdapter;

	/**

	public static void main(String[] args) {
		ICooker qjdCooker=new QjdCooker();
		IProgrammer jdProgrammer=new JDProgrammer();
		Object[] workers={qjdCooker,jdProgrammer};
	
		//创建适配器对象
		IWorkerAdapters adapter=new WorkerAdapter();
		//循环遍历每个工种对象，让每个工种对象在适配器中逐个进行匹配
		for (Object worker : workers) {
			String workerContent=adapter.work(worker);
			System.out.println(workerContent);
		}
	
	}

}
