Java设计模式——适配器设计模式

public class Adapter
{
public static void main(String[] args)
{
PowerA a = new PowerAImpl();
//a.connect();
intput(a);

PowerB b = new PowerBImpl();
//intput(b);//不能这么用，input方法只能接收PowerA的接口

PowerAdapter powerAdapter = new PowerAdapter(b);
intput(powerAdapter);
}

public static void intput(PowerA a)
{
a.connect();
}
}

//适配器
class PowerAdapter implements PowerA
{
private PowerB b;

public PowerAdapter(PowerB b)
{
this.b = b;
}

public void connect()
{
b.insert();
}
}

interface PowerA
{
public void connect();
}

class PowerAImpl implements PowerA
{
public void connect()
{
System.out.println("电源A接口开始工作");
}
}

interface PowerB
{
public void insert();
}

class PowerBImpl implements PowerB
{
public void insert()
{
System.out.println("电源B接口开始工作");
}
}
