socket之線程來提升吞吐量

線程demo:

線程：

package com.company.s5;

import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Socket;

public class BeginThread extends Thread {
    private Socket socket;

    public BeginThread(Socket socket) {
        super();
        this.socket=socket;
    }

    @Override
    public void run() {
        try {
            InputStream inputStream=socket.getInputStream();
            InputStreamReader reader=new InputStreamReader(inputStream);
            char[] charArray=new char[1000];
            int readLength=-1;
            while ((readLength=reader.read(charArray))!=-1){
                String newstring=new String(charArray,0,readLength);
                System.out.println(newstring);
            }
            reader.close();
            inputStream.close();
            socket.close();
        }catch (Exception e){
            e.printStackTrace();
        }
