What is Java technology and why do I need it?
Java is a general purpose high level programming language developed by sun Microsystems. A small team of engineers, known as the Green Team, initiated the language in 1991. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful, so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web .Later, in 2009,Oracle Corporation acquired SunMicrosystem and took ownership of two key Sun software assets: Java and Solaris.
There are lots of application and websites that will not work unless you have 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!
Are created every day. Java is fast
Java: An Object-Oriented Language.
Java is an Object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. Java source code files (files with a .java extension) are complied into a format called byte code (files with a .class extension), which can then be executed by a Java interpreter. Compiled Java code can run on most computers because Java interpreters and runtime environments, known as Java Virtual Machines (VMs), exist for most operating systems, including UNIX, the Macintosh OS, and WINDOWS . Byte code can also be converted directly into MACHINE LANGUAGE instructions by a JUST IN COMPLIER (JIT). In 2007, most Java technologies were released under the GNU General Public License.
Java on the Web.
Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java APPLETS and can be DOWNLOADED from a Web Server and run on your computer by a Java-compatible WEB SEVER.
Applications and websites using Java will not work unless Java is installed on your device. When you download Java, the software contains the Java Runtime Environment (JRE) which is needed to run in Web browser. A component of the JRE, the Java Plug-in software allows java applets to run inside various browsers.
