十：反射

具体详细看：https://blog.csdn.net/qq_36226453/article/details/82790375

目前代码：

　　

package Text;

import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class RunFanShe {
    
    private static final char[] Arcing = null;

    public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, SecurityException, Exception {

        Class<?> forName = Class.forName("Text.Arcing");
        Object newInstance = forName.getConstructor(String.class).newInstance("刘");
        
        Method methods = forName.getMethod("name", int.class);
        
        
        methods.invoke(newInstance, 20);



    }

}

class Arcing{
    public String nameString = "bookfar";
    public void name(int age) {
        System.out.println("my name is "+nameString+age);
    }
    
    public Arcing(String aString) {
        // TODO Auto-generated constructor stub
        this.nameString = aString;
        System.out.println("you got it");
    }
    
    
}

交互例子

package SocketProcess;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

public class SocketClient {
    public static String readLine="hello";
    public static String[] command = {"get", "put"};
    @SuppressWarnings("resource")
    public static void main(String[] args) throws UnknownHostException, IOException {
        Socket socket = new Socket("localhost", 8899);
         BufferedReader systemIn = new BufferedReader(new InputStreamReader(System.in));
         BufferedReader socketIn = new BufferedReader(new InputStreamReader(socket.getInputStream()));
         PrintWriter socketOut = new PrintWriter(socket.getOutputStream());
         

        
        System.out.print("Client:");
        readLine = systemIn.readLine();
        socketOut.println("get");

      
        socketOut.flush();
        
        String inTempString = socketIn.readLine();
        System.out.println(inTempString);
        System.out.println("Server");
                

         
    }
}

class SendMQ{
    public String get() {
        
        return "you get";
    }
    
    public String post() {
        return "you post";
    }
    
}

package SocketProcess;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.lang.reflect.Method;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketServer {
    public static String[] command;
    public static String readLine="hello";
    
    public static void main(String[] args) throws Exception {
        ServerSocket serverSocket = new ServerSocket(8899);
        System.out.println("wite a connect");
        Socket accept = serverSocket.accept();
        
        
        //获取服务器输入  inputStreamReader是字节流转换成字符流
        BufferedReader systemIn = new BufferedReader(new InputStreamReader(System.in));
        BufferedReader sockerIn = new BufferedReader(new InputStreamReader(accept.getInputStream()));
        //printwriter具有自动行刷新的缓冲字符输出流，特点是可以按行写出字符串，并且可以自动行刷新。
        PrintWriter socketOut = new PrintWriter(accept.getOutputStream());
        

        String inTempString = sockerIn.readLine();
        System.out.print("Client:");
        System.out.println(inTempString);
        SendMQ sendMQ = new SendMQ();
        //将Socket发送过来的字符串直接通过反射方法来操作达到交互  注意invoke和getmethod的工作原理，invoke是需要传入实力化参数的，
        Object re =  sendMQ.getClass().getMethod(inTempString).invoke(sendMQ, args);
        
        System.out.println(re);
        System.out.print("Server >>:");
        readLine = systemIn.readLine();
        
        socketOut.println(readLine);
        socketOut.flush();
        }
        
    }
