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.
Re: char to int cov problem
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?

Re: char to int cov problem
Are you sure?the second parameter is the length and not the index you wish to end at.
When in doubt read the documentation.

Maybe Sun/Oracle have it wrong?Originally Posted by Norm
"The substring begins at the specified beginIndex and extends to the character at index endIndex - 1".
