is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written primarily in Java and can be used to develop applications in Java and, by means of the various plug-ins, in other languages as well, including C, C++, COBOL, Python, Perl, PHP, and others. The IDE is often called Eclipse
ADT for Ada, Eclipse
CDT for C, Eclipse
JDT for Java and Eclipse
PDT for PHP.
The initial codebase originated from VisualAge. In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its capabilities by installing plug-ins written for the Eclipse
software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules.
