First compile and run Server in Tencent Cloud
import java.net.*;
import java.io.*;
import java.util.Scanner;
public class Server {
public static ServerSocket soc;
public static Socket sc;
public static void main(String[] args) {
// TODO Auto-generated method stub
Threadin i = new Threadin();
Threadout o = new Threadout();
try {
soc = new ServerSocket(4900);
try {
sc = soc.accept();
print("success");
i.start();
o.start();
}catch(Exception e) {
print(e.toString());
}
}catch(IOException e) {
print("already use");
}
}
public static void print(String s) {
System.out.println(s);
}
static class Threadin extends Thread{
public void run() {
try {
BufferedReader bf = new BufferedReader(new InputStreamReader(sc.getInputStream()));
while(true) {
String str=bf.readLine();
if((str).equals("bye")) {
bf.close();
sc.close();
soc.close();
System.exit(-1);;
}else {
print(str);
}
}
}catch(IOException e) {
print(e.toString());
}
}
}
static class Threadout extends Thread{
public void run() {
try {
Scanner bt = new Scanner(System.in);
PrintWriter pw = new PrintWriter(new BufferedWriter(new OutputStreamWriter(sc.getOutputStream())),true);
pw.println("hello");
while(true) {
pw.println(bt.nextLine());
}
}catch(IOException e) {
print(e.toString());
}finally {
}
}
}
}
Then run Client locally
import java.net.*;
import java.io.*;
import java.util.Scanner;
public class Client {
public static Socket sc;
public static void main(String[] args) {
// TODO Auto-generated method stub
Threadin i = new Threadin();
Threadout o = new Threadout();
try {
sc = new Socket("xxxxxxxxxx",4700);//填ip
//sc = new Socket(InetAddress.getByName("localhost") ,4700);
try {
i.start();
o.start();
}catch(Exception e) {
print(e.toString());
}
}catch(IOException e) {
print(e.toString());
}
}
public static void print(String s) {
System.out.println(s);
}
static class Threadin extends Thread{
public void run() {
try {
BufferedReader bf = new BufferedReader(new InputStreamReader(sc.getInputStream()));
while(true) {
String str=bf.readLine();
if((str)=="bye") {
bf.close();
sc.close();
break;
}else {
print(str);
}
}
}catch(IOException e) {
print(e.toString());
}
}
}
static class Threadout extends Thread{
public void run() {
try {
Scanner bt = new Scanner(System.in);
PrintWriter pw = new PrintWriter(new BufferedWriter(new OutputStreamWriter(sc.getOutputStream())),true);
pw.println("hello");
while(true) {
pw.println(bt.nextLine());
}
}catch(IOException e) {
print(e.toString());
}finally {
}
}
}
}
