java.lang.NumberFormatException: For input string: "9813023219" -


i'm using serial event pass rfid tags read arduino processing. in serial event parsing , converting variable integer. working part, 1 rfid card keeps throwing error.

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);         }        }   } }  void setrfid(string r)   {        try{        this.rfid = integer.parseint(r);      }      catch (exception e) {       e.printstacktrace();      }       //set position of person chair      (person person : people)        {           //println(this.rfid != chair.rfid);         //println(this.rfid + "," +  "person: " + person.id + "," + person.rfid);         if(this.rfid == person.rfid)         {           person.setpos(this.pos);           this.personid = person.id;         }      }   }

the try-catch not working, , line causing problem this.rfid = integer.parseint(r);. thought might malformed string strings seems ok. here results of checking string consistency: string length: 10 1811524219 string length: 10 1942302231 string length: 10 1010368230 string length: 10 9813023219

9813023219 invalid integer greater integer.max_value, 2147483647. use long instead, who's max_value 9223372036854775807.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
