Java™ for Programmers (2nd Edition) (Deitel Developer Series)

Java™ for Programmers (2nd Edition) (Deitel Developer Series), 9780132821544 (0132821540), Prentice Hall, 2011

Welcome to Java—the world’s most widely used computer programming language. In this book, you’ll learn object-oriented programming—today’s key programming methodology.

You’ll create and work with many software objects in this text.

Java is the preferred language for meeting many organizations’ enterprise programming needs. Java has also become the language of choice for implementing Internet-based applications and software for devices that communicate over a network.

In use today are more than a billion general-purpose computers and billions more Java-enabled cell phones, smartphones and handheld devices (such as tablet computers). According to a study by eMarketer, the number of mobile Internet users will reach approximately 134 million by 2013.1 Other studies have projected smartphone sales to surpass personal computer sales in 20112 and tablet sales to account for over 20% of all personal computer sales by 2015.3 By 2014, the smartphone applications market is expected to exceed $40 billion,4 which is creating significant opportunities for programming mobile applications.

Java Editions: SE, EE and ME

Java for Programmers, Second Edition is based on Java Standard Edition 6 (Java SE 6) and Java SE 7. Java is used in such a broad spectrum of applications that it has two other editions. The Java Enterprise Edition (Java EE), which we use later in the book, is geared toward developing large-scale, distributed networking applications and web-based applications.

The Java Micro Edition (Java ME) is geared toward developing applications for small, memory-constrained devices, such as BlackBerry smartphones. Google’s Android operating system—used on numerous smartphones, tablets (small, lightweight mobile computers with touch screens), e-readers and other devices—uses a customized version of Java not based on Java ME.
