服务端:
try {
ServerSocket serverSocket = new ServerSocket(9000);//建立端口号为9000
Socket socket = serverSocket.accept();//等待客户端的连接
InputStream is = socket.getInputStream();//接受客户端的信息流
//接受信息代码模块
byte[] buffer = new byte[1024];
int len;
while ((len=is.read(buffer))!=-1)
{
String msg = new String(buffer, 0, len);
System.out.println(msg);
}
} catch (IOException e) {
e.printStackTrace();
}
import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;
//服务端
public class TcpServer {
public static void main(String[] args) {
try {
ServerSocket serverSocket = new ServerSocket(9000);//建立端口号为9000
Socket socket = serverSocket.accept();//等待客户端的连接
InputStream is = socket.getInputStream();//接受客户端的信息流
//接受信息代码模块
byte[] buffer = new byte[1024];
int len;
while ((len=is.read(buffer))!=-1)
{
String msg = new String(buffer, 0, len);
System.out.println(msg);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
客户端:
public class TcpClient { public static void main(String[] args) { try { InetAddress byName = InetAddress.getByName("127.0.0.1");//ip地址 int port=9000;//端口号 Socket socket = new Socket(byName, port);//建立一个socket连接 OutputStream ou = socket.getOutputStream();//发送io流 ou.write("你好,李焕英".getBytes(StandardCharsets.UTF_8));//getBytes()是将String字符串转换为Byte数组 } catch (Exception e) { e.printStackTrace(); } } }
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.nio.charset.StandardCharsets;
//客户端
public class TcpClient {
public static void main(String[] args) {
try {
InetAddress byName = InetAddress.getByName("127.0.0.1");//ip地址
int port=9000;//端口号
Socket socket = new Socket(byName, port);//建立一个socket连接
OutputStream ou = socket.getOutputStream();//发送io流
ou.write("你好,李焕英".getBytes(StandardCharsets.UTF_8));//getBytes()是将String字符串转换为Byte数组
} catch (Exception e) {
e.printStackTrace();
}
}
}
先运行服务器端,再运行客户端,运行结果如下:
S:\java\jdk\bin\java.exe -javaagent:S:\java\ideaIU-2020.3.2.win\lib\idea_rt.jar=56092:S:\java\ideaIU-2020.3.2.win\bin -Dfile.encoding=UTF-8 -classpath C:\Users\279186856\Desktop\寒假\java学习\GUI_Study\out\production\GUI_Study com.hu.net.TcpServer
你好,李焕英
