用java程序实现

机器人类(源类)：

public class Robot {

public void cry(){

System.out.println("机器人叫");

}

public void run(){

System.out.println("机器人跑");

}

}

狗类(目标类)：

public class Dog {

public void cry(){

System.out.println("像狗一样叫");

}

public void run(){

System.out.println("像狗一样跑");

}

}

适配器类(继承源类并重写它的方法，目标类作为属性)：

public class Adaper extends Robot{

private Dog dog;

public Adaper(Dog dog) {

this.dog=dog;

}

@Override

public void cry() {

dog.cry();

}

@Override

public void run() {

dog.run();

}

}

测试类

public class Test {

public static void main(String[] args) {

Dog dog=new Dog();

Robot robot=new Adaper(dog);

robot.cry();

robot.run();

}

}

java什么是响应代码?

这个不是java有的东西.这是http协议的东西.

http简单的说,包括request和response.

request就是请求,包括请求头,请求参数,请求地址等...

response就是响应.同样包括头,参数,还有一个就是响应码.

响应码代表这次的响应大概是什么结果.(只是大概,并一定准确)

而且响应码超级多,大概的有:

404:告诉你,这个地址不存在.

500:告诉你,我这出bug了.

200:一切顺利,请求成功.

太多太多了...你可以查响应码的解释.

一般情况下,响应码是准确的,但我为啥说不一定准确呢.因为对方给你返回响应时,他可以指定响应码.(有些人喜欢修改http协议的默认设置.比如有些奇葩就想把404理解成响应成功.他就可以设置404.或者他设置2019都可以.)
