World-Wide Web, language (After the Indonesian island, a
source of programming fluid) A simple, object-oriented,
distributed, interpreted, robust, secure,
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 multipleinheritance, and extensive automatic coercions. It has
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
Java has an extensive library of routines for TCP/IP
protocols like HTTP and FTP. Java applications can
access objects across the Internet via URLs as easily as
on the local file system.
The Java compiler and linker both enforce strong typechecking - procedures must be explicitly typed. Java
supports the creation of virus-free, tamper-free systems
The Java compiler generates an architecture-neutral objectfile executable on any processor supporting the Java run-timesystem. 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 NetscapeNavigator version 2.0.
