Welcome to the new version of Practice-it! We've worked to improve the stability and performance of the site, and to improve the user interface.

Update 2016/07/09: We pushed a new version that fixes many bugs that were reported. Thanks to everyone who took the time to report bugs!

If you notice bugs, please let us know.

We're keeping the old version of the site up temporarily, in case this new version has a critical bug which prevents you from using it. Your account information (solved problems, etc) on the old site will not be kept in sync with the new site. Go to old site.

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.

Looking to practice other programming languages? Our sister site, CodeStepByStep.com, offers problems for Java, Python and C++.

Version 4.0.3 (2016/07/21)

(To submit a solution for a problem or to track your progress, you must create an account and log in.)
