    <p>I'm writing a program that has 2 way communication using Sockets. Client Program presents user with some options, when user selects that option it gets processed by Server Program and returns results back to Client Program. I am having some trouble with Server Program because it won't process the PrintWriter statement if I put it inside my conditional statement as you can see bellow.</p> <p>Client:</p> <pre><code>Socket socket = null; try { System.out.println("Connecting to Server"); socket = new Socket("192.168.0.104", 7003); socket.setSoTimeout(10000); System.out.println("Connected"); DataOutputStream os = new DataOutputStream(socket.getOutputStream()); InputStreamReader userInput = new InputStreamReader(System.in); BufferedReader userBuffer = new BufferedReader(userInput); InputStreamReader serverInput = new InputStreamReader(socket.getInputStream()); BufferedReader serverBuffer = new BufferedReader(serverInput); PrintWriter print = new PrintWriter(socket.getOutputStream(), true); System.out.println("Option 1"); System.out.println("Option 2"); System.out.println("Option 3"); String userOption = userBuffer.readLine(); os.writeBytes(userOption); if (userOption.equals("1")) { String line = serverBuffer.readLine(); System.out.println(line); } System.out.println("Closing Client Connection"); serverBuffer.close(); serverInput.close(); print.close(); socket.close(); os.close(); System.exit(0); } </code></pre> <p>Server:</p> <pre><code>ServerSocket serverSock = null; Socket standSock = null; try { serverSock = new ServerSocket(7003); standSock = serverSock.accept(); InputStreamReader input = new InputStreamReader(standSock.getInputStream()); BufferedReader read = new BufferedReader(input); PrintWriter print = new PrintWriter(standSock.getOutputStream(), false); String dateTime = (Calendar.getInstance()).getTime().toString(); if (read.readLine().equals("1")) { System.out.println("Option 1"); print.println("You're connected to the Server at: " + dateTime); } System.out.println("Closing Server Connection"); read.close(); input.close(); print.close(); standSock.close(); } </code></pre> <p>I've tested for user input from Client program and its getting it correctly, but the problem is if I move</p> <pre><code>print.println("You're connected to the Server at: " + dateTime); </code></pre> <p>inside the condition statement the program just hangs and eventually times out, but if I move that statement outside the condition statement it works. Why can't it work if I put it inside my condition statement?</p>

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.
