Java is a programming language invented by James Gosling and developed by Sun Microsystems. It took a bit longer than 10 days to develop — it took closer to four years. In 1991, a group of Sun Microsystem engineers called the “Green Team” worked day and night to create Java.
It was first released in 1995, and several new versions have been launched since then. Today’s Internet is absolutely saturated with Java-run programming, and we have Java to thank for many of the applications that make day-to-day living easier. Java is currently owned by Oracle.
Features of Java:
Compiled and interpreted: In the beginning, Java compiler translates the source code into bytecode. Then machine code is produced which can be straightly executed by the machine, and the interpreter is responsible for doing this.
Platform independent and portable: It can be moved from one machine to another, any modification in the operating systems, system resources, and processor could not affect the java programs. The bytecode generated by a java compiler could be employed on any machine.
Object-Oriented: Java is a purely object-oriented language where everything revolves around the classes and objects.
Distributed: It also enables the creation of applications on the network and can share both data and program. Java can also be used to access remote objects through the internet and allows several programmers to work in tandem from different remote locations.
Dynamic and Extensible: The new classes, objects, methods and libraries are probably dynamically linked in java. It can also support functions written in languages such as C and C++.
Ease of development: Code reusability make development easier.
Scalability and Performance: The scalability and performance can be improved by enhancing the start-up time and minimizing the consumption of memory in Java runtime environment.
Client-side scripting language: It is client-side scripting language which uses a browser to execute the code, and doesn’t involve server interaction. However, the newer versions and frameworks enable server-side scripting also.
Event-based: It is able to run some specific code in the occurrence of some event. An event can be any loading page or submitting a form, etcetera.
