'''GNU Classpath''' is a [[free software]] implementation of the standard [[Java Class Library|class library]] for the [[Java (programming language)|Java programming language]]. Most classes from [[Java Platform, Standard Edition|J2SE]] 1.4 and 5.0 are implemented. Classpath can thus be used to run Java-based [[application software|applications]].  GNU Classpath is a part of the [[GNU Project]]. It was originally developed in parallel with [[GNU Compiler for Java|libgcj]] due to license incompatibilities, but later the two projects merged.

GNU Classpath was deemed a high priority project by the [[Free Software Foundation]].  When the Classpath project began, the [[software license|license]] for the official Java implementation from [[Sun Microsystems]] did not allow distribution of any alterations. Since the inception of the Classpath project, the [[OpenJDK]] was released under the [[GNU General Public License|GPL]] and now serves as the official reference implementation for the [[Java platform]].
