nature: object oriented language
history: Java (named for coffee) was created by James Gosling and others at Sun Microsystems for embedded systems and released for applets in 1995. Original work started in 1991 as an interactive language under the name Oak. Rewritten for the internet in 1994.
“Java is a computer language, but very powerful, intended to be machine and operating-system independent. Java will enable whatever functions the piece you call up or download has, including sound, video, etc., on your screen. It also is interactive, and can produce dynamic images on your screen, not just static ones. It was developed by Sun Micro. There is a dialect called Hot Java; on the other hand, JavaScript is a separate language.” —Language Finger, Maureen and Mike Mansfield Library, University of Montana.
Java should not be confused with Microsoft’s J++. Microsoft was worried about the success of Java for two reasons: (1) Java directly competed with Windows CE as a system for embedded devices, and (2) Java is cross-platform and therefore threatens the dominance of Windows. So, Microsoft created their own version of Java, which was purposely slightly different. In addition to adding a few Microsoft-only objects (available only when used on the latest versions of Windows) and dropping a few general Java objects, Microsoft purposely made some objects behave differently in their version than in pure Java. The prupose was to sew confusion and cause Java programs written on Microsoft platforms to fail on other platforms and Java programs written on other platforms to fail on Microsoft platforms, hoping this would lead to a widespread belief that Java was unreliable. For a period of time, Sun used the “Pure Java” slogan to try to distinguish between Microsoft’s version and the real thing. Eventually Sun won in court and and got a U.S> federal court order preventing Microsoft from calling their own language “Java”. Microsoft was forced to switch to an alternate name (“J++”).
