Introduction to Java

Java is designed to meet the challenges of application development in the
context of heterogeneous, network—wide distributed environments. Paramount among
these challenges is secure delivery of applications that consume the minimum of
system resources， can run on any hardware and software platform, and can be extended
dynamically。
Java originated as part of a research project to develop advanced software for
a wide variety of network devices and embedded systems. The goal was to develop a
small， reliable， portable， distributed, real-time operating platform。 When the
project started， C++ was the language of choice。 But over time the difficulties
encountered with C++ grew to the point where the problems could best be addressed
by creating an entirely new language platform. Design and architecture decisions
drew from a variety of languages such as Eiffel ， SmallTalk, Objective C, and
Cedar/Mesa. The result is a language platform that has proven ideal for developing
secure， distributed, network based end-user applications in environments ranging from
network—embedded devices to the World-Wide Web and the desktop.
The design requirements of Java are driven by the nature of the computing
environments in which software must be deployed.
The massive growth of the Internet and the World-Wide Web leads us to a
completely new way of looking at development and distribution of software. To live
in the world of electronic commerce and distribution， Java must enable the development
of secure, high performance, and highly robust applications on multiple platforms
in heterogeneous， distributed networks.
Operating on multiple platforms in heterogeneous networks invalidates the
traditional schemes of binary distribution, release, upgrade， patch， and so on。 To
survive in this jungle， Java must be architecture neutral, portable, and dynamically
adaptable。
The Java system that emerged to meet these needs is simple, so it can be
easily programmed by most developers； familiar, so that current developers can easily
learn Java ； object oriented ， to take advantage of modern software development
methodologies and to fit into distributed client-server applications ；
multithreaded， for high performance in applications that need to perform multiple
