Java is a set of computer software and specifications that provides a system for developing application software and deploying it across multiple platforms. It is widely used to develop networked applications, embedded systems, mobile applications, games, web content and enterprise software. With millions of developers worldwide, Java enables efficient development and use of exciting applications.

1. Java is a set of several computer software and specifications
developed by Sun Microsystems, later acquired by Oracle
Corporation, that provides a system for developing application
software and deploying it in a cross-platform computing
environment.
Java is the foundation for virtually every type of networked
application and is the global standard for developing and delivering
embedded and mobile applications, games, Web-based content, and
enterprise software. With more than 9 million developers
worldwide, Java enables you to efficiently develop, deploy and use
exciting applications and services.

2. What is Java Platform?
 The Java platform is a suite of programs that facilitate developing and
running programs written in the Java programming language. Java Platform
is an execution engine (called a virtual machine) and a compiler with a set
of libraries implemented for various hardware and operating systems so that
Java programs can run identically on all of them.
 Multiple platforms, each targeting a different class of devices:
 Java Card: A technology that allows small Java-based applications (applets)
to be run securely on smart cards and similar small-memory devices.
 Java ME (Micro Edition): Specifies several different sets of libraries
(known as profiles) for devices with limited storage, display, and power
capacities. Often used to develop applications for mobile devices, PDAs,
TV set-top boxes, and printers.
 Java SE(Standard Edition): For general-purpose use on desktop PCs, servers
and similar devices.
 Java EE( (Enterprise Edition): Java SE plus various APIs useful for multi-
tier client–server enterprise applications.

3. Where is Java used?
• From laptops to datacenters, game consoles to scientific supercomputers,
cell phones to the Internet, Java is everywhere!
 97% of Enterprise Desktops Run Java
 89% of Desktops (or Computers) in the U.S. Run Java
 9 Million Java Developers Worldwide
 #1 Choice for Developers
 #1 Development Platform
 3 Billion Mobile Phones Run Java
 100% of Blu-ray Disc Players Ship with Java
 5 Billion Java Cards in Use
 125 million TV devices run Java
 5 of the Top 5 Original Equipment Manufacturers Ship Java ME

4. Why Developers Choice?
 Java has been tested, refined, extended, and proven by a dedicated
community of Java developers, architects and enthusiasts. By making
applications available across heterogeneous environments, businesses can
provide more services and boost end-user productivity, communication, and
collaboration—and dramatically reduce the cost of ownership of both
enterprise and consumer applications.

5. RealWorld Java Projects
• Android Apps:-Open your Android phone and any app, they are actually
written in Java programming language, with Google's Android API, which
is similar to JDK.
• Financial Service Industries:-Java is very big in Financial Services. Lots
of global Investment banks like Goldman Sachs, Citigroup, Barclays,
Standard Charted
• WebApplications:-Many of government, healthcare, insurance, education,
defense and several other department have their web application built in
Java.
• Ex:IRCTC
• SoftwateTools:-Eclipse, InetelliJ Idea and Netbeans IDE various tools are
developed in Java.
• Scientific Applications:-Java is often a default choice for scientific
applications, including natural language processing. Main reason of this is
because Java is more safe, portable, maintainable and comes with better
high-level concurrency tools than C++ or any other language.
