    copied!<p>Hopefully a very simple query, but it's left me scratching my head.</p> <p>I have a string, which is just a single integer, and I'm trying to then get that integer out as an int. This on the face of it shouldn't be a problem.</p> <pre><code>// this is how I create the string (it's the playload from a UDP datagram packet, // thought I don't think the origins hugely important - it's juts a test run so the // stringMessage is always 1 (created by a seperate client process) ... recvSoc.receive(pac); String stringMessage = new String(pac.getData()); port = pac.getPort(); System.out.println("RECEIVED: " + stringMessage + " on port: " + port); processMessage(stringMessage); ... // Then in processMessage public void processMessage(String data) { int message; message = Integer.parseInt(data); ... </code></pre> <p>This always crashes with a NumberFormatException error. I cannot for the life of me figure out what's causing this, any ideas greatly appreciated. I haven't coded much in Java (recently) so might simply be forgetting something critical or what not.</p> <pre><code>Exception in thread "main" java.lang.NumberFormatException: For input string: "1" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) at java.lang.Integer.parseInt(Integer.java:481) at java.lang.Integer.parseInt(Integer.java:514) at udp.UDPServer.processMessage(UDPServer.java:85) at udp.UDPServer.run(UDPServer.java:52) at udp.UDPServer.main(UDPServer.java:156) </code></pre>
