    <p>I have three classes. When the server starts, it creates a randomGame object with a guessCount and random number. When the client starts, it connects to the server and passes the number to server to play the guess method(with console input number) to guess the random number of the randomGame generated.</p> <p>But the following has problems. The client enter the number each time, the guessCount &amp; the random number are reinitialized(that is, the random number is different and guessCount can't increment). I want the random number to be the same for each client program running and the guessCount will be incremented by 1 each time when the guess method run.</p> <pre><code>public class Game { private int num; private int guessCount; Game (int num) { this.num = num; System.out.println("guessCount = " + guessCount); System.out.println("num = " + num); } public int guess (int ran) { int result; guessCount++; if (this.guessCount &gt;= 10) { return -2; } else if (ran &lt; num) { return -1; } else if (ran &gt; num) { return 1; } else { return 0; } } } </code></pre> <p>Here's <code>RandomGame</code></p> <pre><code>class RandomGame extends Game { RandomGame () { super(0 + (int)(Math.random() * ((90 - (0)) + 1))); } public static void main (String args[]) { } } </code></pre> <p>Here's the server:</p> <pre><code>import java.io.*; import java.net.*; public class Q4Server { public static void main(String arg[]) { try { ServerSocket ss = new ServerSocket(12345); while(true) { Socket s = ss.accept(); ClientHandler ch = new ClientHandler(s); ch.start(); } } catch(IOException ioe) { ioe.printStackTrace(); } } } </code></pre> <p>Here's the client handler:</p> <pre><code>class ClientHandler extends Thread { Socket socket; RandomGame g; public ClientHandler(Socket socket) { this.socket = socket; g = new RandomGame(); } public void run() { try { DataInputStream dis = new DataInputStream(socket.getInputStream()); DataOutputStream dos = new DataOutputStream(socket.getOutputStream()); int x = dis.readInt(); int reply = this.g.guess(x); System.out.println("reply = " + reply); dos.writeInt(reply); //System.out.println(reply); //System.out.println(reply); socket.close(); } catch(IOException ioe) { ioe.printStackTrace(); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
