This is creating significant career opportu-
nities for people who program mobile applications, many of which are programmed in Java
(see Section 1.6.3).
Java Standard Edition
Java has evolved so rapidly that this tenth edition of
Java How to Program
—based on
Java
Standard Edition 7 (Java SE 7)
and
Java Standard Edition 8 (Java SE 8)
—was published
just 17 years after the first edition. Java Standard Edition contains the capabilities needed
to develop desktop and server applications. The topic
can be used with
either
Java SE 7
or
Java SE 8 (released just after this topic was published). All of the Java SE 8 features are
discussed in modular, easy-to-include-or-omit sections throughout the topic.
Prior to Java SE 8, Java supported three programming paradigms—
procedural pro-
gramming
,
object-oriented programming
and
generic programming
. Java SE 8 adds
functional
programming
. In Chapter 17, we'll show how to use functional programming to write pro-
grams faster, more concisely, with fewer bugs and that are easier to
parallelize
(i.e., perform
multiple calculations simultaneously) to take advantage of today's multi-core hardware
architectures to enhance application performance.
Java Enterprise Edition
Java is used in such a broad spectrum of applications that it has two other editions. The
Java Enterprise Edition (Java EE)
is geared toward developing large-scale, distributed net-
working applications and web-based applications. In the past, most computer applications
ran on “standalone” computers (computers that were not networked together). Today's
applications can be written with the aim of communicating among the world's computers
via the Internet and the web. Later in this topic we discuss how to build such web-based
applications with Java.
