History of Java Programming Language
Java is class-based and general-purpose object-oriented computer programming language which is specially designed to have some implementation dependencies as possible. It is developed by James Gosling at Sun Microsystems in the early 1990s. This programming language is intended to be compiled to byte code which is practically developed to either compile to native code or to be interpreted from source code at runtime. Actually, it brings much syntax from C & C++ and also has easier object models.
In the June 1991, Java programming language was started as project called “Oak” by James Gosling. He actually wants to implement virtual machine as well as language which had familiar C-like notation. It is also known as platform-independent language which also allows you to communicate with appliances including video game consoles as well as VCRs. This language made promise of “Write Once, Run Anywhere” with free runtimes on some of the well-known platforms. It simply enables you to access files as well as network connectivity with complete security.
Some Significant Language Features:
- Platform Independence: Here, Java compilers doesn’t generate native object code for any specific platform but rather than produce ‘byte code’ instructions for Java Virtual Machine (JVM).
- Object Orientation: Java is purely object-oriented language which means that each & everything included in the program is an object and is simply descended from root object class.
- Standard Library: It is most popular and well-known feature is its library which comes with wide-ranging assortment of methods as well as classes in six main functional areas. This language support classes for some advanced language features including arrays, threads, exception handling and strings.
- Applet Interface: Now it is possible to create stand-alone applications as well as programs which can be easily downloaded from web page and also run on client browser.
- Familiar C++-like Syntax: Java object-oriented programming language is as similar as syntax of one of the most popular C++ programming language.
- Garbage Collection: This language doesn’t need any kind of skilled programmers in order to dynamically allocated free memory which intelligently makes it even easier.
Areas of Applications:
- Cross-Platform Application Development
- World wide Web Applets
- Other Network Applications
Java is widely-used general purpose programming language with various features which make it suitable to use on World Wide Web. All these small Java applications are called as java applets that can be easily downloaded from web server. You can also run it on your computer by any compatible Java web browser including Microsoft Internet Explorer as well as Netscape Navigator.
