适配器模式

适配器就是将一个类适配成另一个类 示例代码:

public interface Dog {

	void wangwang();
}
public class Husky implements Dog{

	@Override
	public void wangwang() {
		System.out.println("husky wangwang");
	}

}
public interface Cat {

	void miaomiao();
}
public class LittleCat implements Cat{

	public void miaomiao(){
		System.out.println("miaomiao");
	}
}
public class CatAdapter implements Dog{

	private Cat cat;
	public CatAdapter(Cat cat) {
		this.cat = cat;
	}
	@Override
	public void wangwang() {
		cat.miaomiao();
	}

}
public class Test3 {
	public static void main(String[] args) {
		Cat cat = new LittleCat();
		Dog dog = new CatAdapter(cat);
		dog.wangwang();
	}
}
