设计模式问答适配器模式

Target.java

package com.lucas.ModelAdapter;

public abstract class Target {
	public void Request() {
		System.out.println("Target request!");
	}
}

Adaptee.java

package com.lucas.ModelAdapter;

public class Adaptee {
	public void specificRequest() {
		System.out.println("Adaptee request!");
	}
}

Adapter.java

package com.lucas.ModelAdapter;

public class Adapter extends Target {
	private Adaptee adaptee= new Adaptee();
	
	@Override
	public void Request() {
		adaptee.specificRequest();
	}
}

类比STL中stack  queue 的实现，是对deque双端队列的适配，stack的pop实际上是对deque一段的pop，stack调用适配器类，适配器再调用deque类。
