The JavaPLT group is pleased to announce that DrJava recently passed
the milestone of one million downloads since its inception as a
SourceForge open source project in 2002. The DrJava developers want to
thank all the users of DrJava for making the project so successful.
DrJava is a lightweight integrated development environment (IDE) for
writing Java programs. It is designed primarily for students,
providing an intuitive interface and the ability to interactively
evaluate Java code in an “Interactions Pane”. It also includes
powerful features for more advanced users including the DrJava
developers. DrJava is freely distributed under the BSD License, and it
is still under active development by the JavaPLT group at Rice
The development of DrJava began in 2001, lead by Professor Robert
“Corky” Cartwright of the Computer Science department, with the first
release being made available in Spring 2002. From the beginning, the
DrJava source code emphasized the use of Java generics, novel at the
time. Early in the evolution of DrJava, support for Java generics was
added to the Interactions Pane. After the addition of a project
facility in 2004 and improved support for large projects beginning in
2006, DrJava experienced a sharp increase in popularity.
DrJava is a cross-platform application available for Windows, Mac OS
and Linux. DrJava supports several different Java compilers, including
Oracle/Sun’s JDK, OpenJDK, the Eclipse Java Compiler, as well as
research compilers such as NextGen and Java Mint. In 2005, DrJava
introduced support for a hierarchy of Java language levels, a
pedagogic framework that helps beginners learn Java by partitioning
the language into levels of increasing syntactic complexity.
Since the inception of the DrJava project, over 60 students have
contributed to DrJava in Professor Cartwright’s class on Production
Programming or as part of independent study projects. DrJava is now
being used at institutions across the globe, including the University
of Pennsylvania, Cornell University, Georgia Tech, University of
California-San Diego, University of Washington, UniversitÃ© de Nice
Sophia-Antipolis, National Unversity Singapore and Rice University.
DrJava has also been used as teaching tool in books by Pearson
Education and Wiley Higher Education.
