适配器(Adapter)模式

将一个类的接口，转换为客户期望的另一个接口

public interface Duck {
    public void quack();
}
public interface Turkey {
    public void gobble();
}
public class WildTurkey implements Turkey{
    @Override
    public void gobble() {
        System.out.println("gobble!");
    }
}
public class TurkeyAdapter implements Duck{
    Turkey turkey;

    public TurkeyAdapter(Turkey turkey) {
        this.turkey = turkey;
    }

    @Override
    public void quack() {
        turkey.gobble();
    }
}
public class DuckTestDrive {
    public static void main(String[] args) {
        Turkey turkey = new WildTurkey();
        Duck duck = new TurkeyAdapter(turkey);
        duck.quack();
    }
}
