JavaOS

JavaOS is a discontinued operating system based on a Java virtual machine. It was originally developed by Sun Microsystems. Unlike Windows, macOS, Unix, or Unix-like systems which are primarily written in the C or C++ programming languages, JavaOS is primarily written in Java. It is now considered a legacy system. The Java programming language was introduced by Sun in May 1995. Jim Mitchell and Peter Madany at JavaSoft designed a new operating system, codenamed Kona, written completely in Java. In March 1996, Tom Saulpaugh joined the now seven-person Kona team to design an input/output (I/O) architecture, having come from Apple as Macintosh system software engineer since June 1985 and co-architect of Copland. JavaOS was first announced in a Byte article. In 1996, JavaSoft's official product announcement described the compact OS designed to run "in anything from net computers to pagers". In early 1997, JavaSoft transferred JavaOS to SunSoft.
