title: Can single String contain multiple lines?
body: <p>For example if I assign multiple lines to a string as so:</p>
  
  <pre><code>while ((line = reader.readLine()) != null)
          {
              output += line + "\n";
          }
  </code></pre>
  
  <p>Is it possible for me to return output with line separators as one String?</p>
  
  <p>I'm writing a Socket program that has Client and Server program, where Client sends request to Server and server returns that request in form of a String back to Client, but some String are multiple lines.</p>
  
  <p>Server Program code (part of code):</p>
  
  <pre><code>if (clinetChoice.equals("3"))
      {
          String command = "free";
  
          Process process = Runtime.getRuntime().exec(command);
  
          BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
  
          System.out.println("You Chose Option Three");
  
          String line;            
  
          while ((line = reader.readLine()) != null)
          {
              output += line;
              System.out.println(line);
              line = reader.readLine();
          }
  
      }
  </code></pre>
  
  <p>Client Program code:</p>
  
  <pre><code>while ((fromServer = input.readLine())+"\n" != null)
      {
          System.out.println("Server: " + fromServer);            
          if (fromServer.equals("Bye"))
              break;          
  
          System.out.print("Enter your choice: ");
          fromClient = stdIn.readLine().trim();
  
          if(fromClient.equals("1"))
          {
              System.out.println("Client: " + fromClient);
              output.println(fromClient);
  
          }
  </code></pre>
  
  <p>fromServer in Client program is output from Server program.  This works fine for output that's one line, but if its multiple lines I can't figure out how to print it all at once.</p>
  
  <p>So if output for example equals:  </p>
  
  <pre><code>One
  Two
  Three
  Four
  </code></pre>
  
  <p>It returns as this:</p>
  
  <pre><code>One
  Enter your choice:  (It prompts me for new command)
  Two
  Enter your choice:
  Three
  Enter your choice:
  Four
  </code></pre>
  
  <p>So it basically prints one line, ask me for new choice and doesn't matter what I enter it prints second line, then third line and so forth until it reaches last line, instead of printing like this:</p>
  
  <pre><code>One
  Two
  Three
  Four
  Enter your choice:
  </code></pre>
