Google can!

A quick google using your subject copy and pasted as the search term gave over 200,000 hits: http://www.google.co.uk/search?sourceid=chrome&ie=UTF-8&q=ThreadLocal+variable+in+Java[^]

The top hit explains it pretty nicely: Class ThreadLocal[^]

Learn to use Google: it is a lot faster and less effort than asking a question like this!
