title: java.lang.NumberFormatException: For input string: "9813023219"
body: <p>I'm using serial event to pass rfid tags read from arduino to processing. In the serial event I am parsing and converting the variable to an integer. This working for the most part, only one rfid card keeps throwing an error.</p>
  
  <pre><code>void serialEvent(Serial thisPort)
  {
    String inString = thisPort.readString();
    if(inString != null)
    {
      Serial connect1 = (Serial) connections.get(0);
        if(thisPort == connect1 )
        {
          Chair chair = (Chair) chairs.get(0);
          if(inString.contains("UID Value:"))
          {
            int p2 = inString.indexOf(":");
            String pString = inString.substring(p2+1); 
            String pString2 = pString.substring (0,10);
            //println(pString2);
            pString2.trim();
  
            println("String length: " + pString2.length());
  
            chair.setRFID(pString2);
            println(pString2);
          }
  
        }
    }
  }

    {

         this.rfid = Integer.parseInt(r);
       }

          //println(this.rfid + "," +  "person: " + person.ID + "," + person.RFID);
          if(this.rfid == person.RFID)
          {

  <p>The try-catch is not working, and this line is causing the problem this.rfid = Integer.parseInt(r);. I thought it might be a malformed string but the strings seems ok. Here the results of checking string consistency:
  String length: 10
  1811524219
  String length: 10
  1942302231
  String length: 10
  1010368230
  String length: 10
  9813023219</p>
