What is Java technology and why do I need it?
Java is a programming language and computing platform first released by
Sun Microsystems in 1995. There are lots of applications and websites
that will not work unless you have Java installed, and more are created
every day. Java is fast, secure, and reliable. From laptops to
datacenters, game consoles to scientific supercomputers, cell phones to
the Internet, Java is everywhere!
Why should I upgrade to the latest Java version?
The latest Java version contains important enhancements to improve
performance, stability and security of the Java applications that run on
your machine. Installing this free update will ensure that your Java
applications continue to run safely and efficiently.
Java
runtime environment (JRE) - runtime environment created by Sun
Microsystems that allows to run and use applications written in the
programming language Java. It consists of a virtual machine - java
Virtual Machine and Java-library classes. Written in the java language a
lot of programs and games, especially those for whom mobility is
important. Some Web pages are also using Java. One of the advantages of
java is its cross-platform, that is, applications written in this
language can be used on different operating systems where you installed
java runtime environment (JRE).
Java Development Kit (JDK) -
freeware Oracle Corporation Developer Kit applications written in Java,
including a compiler java (javac), the standard class library Java,
examples, ********ation, various utilities and executive system java
(JRE). In the JDK does not include an integrated development environment
for java (IDE), so the developer using only JDK, is forced to use an
external text editor and compile their programs using the command line
utility.
Key features
automatic memory management;
advanced exception handling;
rich set of filtering I / O;
a set of standard collections such as array, list, stack, and so on;
availability of simple tools for building network applications (including the protocol RMI);
existence of classes that perform HTTP-requests and process responses;
built into the language tools for creating multi-threaded applications;
unified access to databases:
at the level of SQL-queries - based on JDBC, SQLJ;
at
the concept of objects that are able to store in a database - based on
java Data Objects (English) and the java Persistence API (English);
template support (version 1.5);
parallel execution of programs.
Java allows you to play online
games, chat with people around the world, calculate your mortgage
interest, and view images in 3D. These applications, written in the Java
programming language and access from your browse, are called applets.
Corporations also use Java applets for intranet applications and other
ebusiness solutions. Java is used by companies in all major industries.
Whether deployed on cell phones, embedded devices, game consoles,
laptops, or in datacenters, Java offers the rich user interface,
performance, versatility, portability, and security that todays
networked applications require. Java Platform Standard Edition software
is the premier platform for rapidly developing and deploying secure,
portable applications that run on server and desktop systems spanning
most operating systems. JRE contains the Java virtual machine, runtime
class libraries, and Java application launcher that are necessary to run
programs written in the Java programming language.
Key features:
Write software on one platform and run it on practically any other platform
Create programs to run within a web browser and web services
Develop server side applications for online forums, stores, polls, HTML forms processing, and more
Combine Java technology-based applications or services to create highly customized applications or services
Write
powerful and efficient applications for mobile phones, remote
processors, low-cost consumer products, and practically any device with a
digital heartbeat
Java is one of the most popular application platforms on the planet. Which version of Java is right for you?
Java
Platform, Standard Edition (Java SE) is the best platform for
development of desktop, server and high end embedded devices, and it is
the most versatile runtime for Java as well as many other languages.
Java
Platform, Micro Edition (Java ME) is the best software for
resource-constrained embedded devices and has seen widespread deployment
across mobile handsets and digital television devices.
Java
Platform, Enterprise Edition (Java EE) is the standard for delivering
secure, robust, scalable, multi-platform applications and services
across the enterprise, from server and desktop applications to wireless
and wireline applications.
