Dealing with multiple lines String return
<p>I have one program that basically returns a String that can be sometimes one line (which works fine) but other times it can be multiple lines which causes me problems.  Basically I have user choose an option that gets sent to second program and based on that option it returns a certain String.  However if I put user selection outside my loop it works fine if String returned is multiple lines, but I need it to keep prompting users with options menu until they choose to quit.  Here is the code for that:</p>

<pre><code>System.out.print("Enter your choice: ");
fromClient = stdIn.readLine().trim();

while ((fromServer = input.readLine()) != null)
    {
        System.out.println("Server: " + fromServer);            
        if (fromServer.equals("Bye"))
        break;          


        if(fromClient.equals("1"))
        {
            System.out.println("Client: " + fromClient);
            output.println(fromClient);

        }
        if(fromClient.equals("2"))
        {
            System.out.println("Client: " + fromClient);
            output.println(fromClient);

        }
        if(fromClient.equals("3"))
        {
            System.out.println("Client: " + fromClient);
            output.println(fromClient);

        }
        if(fromClient.equals("4"))
        {
            System.out.println("Client: " + fromClient);
            output.println(fromClient);
            break;

        }


    }

<p>This as I mentioned above returns multi-line String fine, but it doesn't prompt user anymore for option selection.  If I move the user selection inside the loop and multi-line String gets returned it prints one line, asks user for their selection, prints second line, asks user for their selection, prints third line, asks user for their selection...</p>
