PLEASE NOTE: We appreciate the value that many instructors have received from the Practice-It service over the years. As you may know, Practice-It has been undergoing an internal review, and it has been determined that we can no longer support the general availability of instructor accounts and courses. As of July 20, 2020, these features were discontinued within the application.

Practice-it is a web application to help you practice solving Java programming problems online. Many of the problems come from the University of Washington's introductory Java courses.

To use Practice-it, first create an account, then choose a problem from our list. Type a solution and submit it to our server. The system will test it and tell you whether your solution is correct.
