char to int cov problem

I have thread name coming into ll

Thread-99

but for Thread-9 ,this conversion return errors :please suggest me a code to convert the name of thread to only INT type number

String a=ll.substring(7,9);

String ll=Thread.currentThread().getName();
String a=ll.substring(7,9);
int i = Integer.valueOf(a).intValue();

Will the thread name always be in that format? You can find the index of the hyphen and substring from there to the end. Or you can use a regular expression to remove all non-digits chars.

By the way ll is a realy bad variable name. Is it 2 capital i's or capital i lowercase el or lowercase el capital i or 2 lowercase el's?

edit: nvm, haven't had my coffe yet ^^

the second parameter is the length and not the index you wish to end at.

Are you sure?
When in doubt read the documentation.

Maybe Sun/Oracle have it wrong? ;)

"The substring begins at the specified beginIndex and extends to the character at index endIndex - 1".
