Java如何使通訊端向單個用戶端顯示訊息？

在Java程式設計中，如何使用通訊端向單個用戶端顯示訊息？

以下範例演示了如何使用Socket類的ssock.accept()方法向單個通訊端用戶端上顯示訊息。

package com.yiibai;

import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketSingleClient {
    public static void main(String args[]) throws Exception {
        ServerSocket ssock = new ServerSocket(1234);
        System.out.println("Listening : ");
        Socket sock = ssock.accept();
        ssock.close();
        PrintStream ps = new PrintStream(sock.getOutputStream());

        for (int i = 10; i >= 0; i--) {
            ps.println(i + " from Java Source and Support.");
        }
        ps.close();
        sock.close();
    }
}

上述程式碼範例將產生以下結果 -

Listening ：
10 from Java Source and Support
9 from Java Source and Support
8 from Java Source and Support
7 from Java Source and Support
6 from Java Source and Support
5 from Java Source and Support
4 from Java Source and Support
3 from Java Source and Support
2 from Java Source and Support
1 from Java Source and Support
0 from Java Source and Support
