适配器模式

一）适配器模式应用场景：

   

     将一个类的接口转换成为客户希望的另外一个接口；使得原本接口不兼容而不能一起工作的那些类可以一起工作；

 

二）类图如下：(实例参考网络)

 

 

 

 

三）.程序代码如下(参考于网络)：

 

    

public class TeaCup
{
	public void steepTeaBag(TeaBag teaBag)
	{
		teaBag.steepTeaInCup();
	}
}

 

public class TeaBag
{
	boolean teaBagIsSteeped;

	public TeaBag()
	{
		teaBagIsSteeped = false;
	}

	public void steepTeaInCup()
	{
		teaBagIsSteeped = true;
		System.out.println("tea bag is steeping in cup");
	}
}

 

 

public class TeaBall extends TeaBag
{
	private LooseLeaf looseLeaf;

	public TeaBall(LooseLeaf looseLeafTeaIn)
	{
		looseLeaf = looseLeafTeaIn;
		teaBagIsSteeped = looseLeaf.teaIsSteeped;
	}

	public void steepTeaInCup()
	{
		looseLeaf.steepTea();
		teaBagIsSteeped = true;
	}
}

 

 

public class LooseLeaf
{
	boolean teaIsSteeped;

	public LooseLeaf()
	{
		teaIsSteeped = false;
	}

	public void steepTea()
	{
		teaIsSteeped = true;
		System.out.println("tea is steeping");
	}
}

 

 

class Test
{

	public static void main(String[] args)
	{
		TeaCup teaCup = new TeaCup();

		System.out.println("Steeping tea bag");
		TeaBag teaBag = new TeaBag();
		teaCup.steepTeaBag(teaBag);

		System.out.println("Steeping loose leaf tea");
		LooseLeaf looseLeaf = new LooseLeaf();
		TeaBag teaBag2 = new TeaBall(looseLeaf);
		teaCup.steepTeaBag(teaBag2);
	}
}
