Welcome to Java ,the world's most widely used computer programming language. You're
already familiar with the powerful tasks computers perform. 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, smart phones 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 smart-phone 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 smart-phone 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 has evolved so rapidly that this ninth edition of Java How to Program based on Java
Standard Edition 6 (Java SE 6) with optional modules on the new features of Java SE 7
was published just 14 years after the first 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 networking 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 book we discuss how to build such web-based applications with Java.
The Java Micro Edition (Java ME) is geared toward developing applications for
small, memory-constrained devices, such as BlackBerry smart-phones. 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.
