Java : convert a String to Int (Unknown Source) [duplicate]

Question

In Java I try to convert a string value into an integer, removing the 4 last characters, so I tried like that :

 String filename1="98597598684.txt";
 int id = Integer.parseInt(filename1.substring(0,  filename1.length()-4));

but I get this error, and I don't understand why :

 java.lang.NumberFormatException: For input string: "98597598684"
at java.lang.NumberFormatException.forInputString(Unknown Source)

it's probably sthg simple but that makes me crazy since 1 hour, any idea?

A solution-seeking tip: in this case you would have probably found answers in far less than an hour if you had googled "at java.lang.NumberFormatException.forInputString". That produced this existing stackoverflow thread for me as the first hit: stackoverflow.com/questions/13935167/… . Exceptions are your friend, google the living daylight out of them :) — Gimby

98597598684 is greater than Integer.MAX_VALUE. Use

long id = Long.parseLong(filename1.substring(0, filename1.length() - 4));
