Java
(After the Indonesian island, a
source of {programming fluid}) A simple, {object-oriented},
{distributed}, {interpreted}, robust, secure,
{architecture-neutral}, {portable}, {multithreaded}, dynamic,
buzzword-compliant, general-purpose programming language
developed by {Sun Microsystems} in 1995(?). Java supports
programming for the {Internet} in the form of
{platform}-independent Java "applets".
Java is similar to {C++} without {operator overloading}
(though it does have {method} overloading), without {multiple
inheritance}, and extensive automatic {coercions}. It has
automatic {garbage collection}.
Java programs can run stand-alone on small computers. The
{interpreter} and {class} support take about 40 kilobytes;
adding the standard libraries and {thread} support
(essentially a self-contained {microkernel}) adds an
additional 175Kb.
Java extends {C++}'s {object-oriented} facilities with those
of {Objective C} for {dynamic method resolution}.
Java has an extensive library of routines for {TCP/IP}
{protocols} like {HTTP} and {FTP}. Java applications can
access objects across the {Internet} via {URL}s as easily as
on the local {file system}.
The Java compiler and {linker} both enforce {strong type
checking} - procedures must be explicitly typed. Java
supports the creation of {virus}-free, tamper-free systems
with {authentication} based on {public-key encryption}.
The Java compiler generates an {architecture-neutral} {object
file} executable on any processor supporting the Java {run-time
system}. The object code consists of {bytecode} instructions
designed to be both easy to interpret on any machine and
easily translated into {native} {machine code} at load time.
The Java libraries provide portable interfaces. For example,
there is an abstract Window class and implementations of it
for {Unix}, {Microsoft Windows} and the {Macintosh}. The
run-time system is written in {POSIX}-compliant {ANSI C}. Java
applets can be executed as attachments in {World-Wide Web}
documents using either Sun's {HotJava} browser or {Netscape
Navigator} version 2.0.
