博客展示了 Java 中使用 Socket 实现简单服务器和客户端的代码。服务器在端口 5432 监听连接，接收连接后发送消息；客户端连接到指定地址和端口，接收并打印消息。代码包含输入输出流操作及异常处理。

public class SimpleServer {

Socket s1;
String sendString = "Hello Net World!";
OutputStream s1out;
DataOutputStream dos;

// Register your service on port 5432
try {
s = new ServerSocket(5432);
} catch (IOException e) { }

// Run the listen/accept loop forever
while (true) {
try {
// Wait here and listen for a connection
s1=s.accept();

// Get a communication stream for soocket
s1out = s1.getOutputStream();
dos = new DataOutputStream (s1out);

// Send your string! (UTF provides machine-independent format)
dos.writeUTF(sendString);

// Close the connection, but not the server socket
s1out.close();
s1.close();
} catch (IOException e) { }
}
}
