Java is a general purpose, high level, object oriented, concurrent programming language. It is platform independent language that means that Java uses a virtual machine over the operating system, called Java Virtual Machine (JVM).
JVM consists of Java Runtime Environment (JRE) and Java Development Kit (JDK).
JVM is the most important component of Java Platform.
Java is
Simple and Easy: Java is based on C++ language. familiarity language C makes it easy to understand Java.
Java is
Reliable: Java uses Garbage Collection to remove unused or unreferenced objects. So, programmer have to not worry about memory management, it is done automatically in Java.
Object oriented: Java is object oriented programming language. All the program code, functions, data are reside in the form of object and classes.
Java uses many object oriented programming paradigms like:
a) Object and Classes
b) Encapsulation
c) Inheritance
d) Polymorphism
Java uses these object concepts.
Multithreading: Java provides the feature of doing multiple tasks at same time with the multithreading concepts. Programmer can manage multiple programs to perform at same time.
Platform Independent/Portable: Java is platform independent with the help of JVM, it can run on any machine. JVM converts code into Bytecode that is readable by any Operating System’s JVM.
Secure: Java does not provides direct pointers to the memory hence it is very secure because you cannot go to the memory directly. Java does not compromise with the data integrity, it makes it very secure.
Java programming language was developed for providing television set up boxes and was developed by James Gosling and his team at Sun Microsystem in the year 1995.
Uses of Java
Java is used in almost every field. Java is mostly used where data security and integrity is very important and cannot be compromised.
Java is used almost everywhere
a. Financial sector
b. Retail: Used to create retail billing applications.
c. Android: Android’s SDK is completely written in Java and uses
java libraries and classes.
d. Big Data: Hadoop MapReduce is written in Java.
e. Computational or Scientific Research: Java is used in Computation and Scientific Research as it requires to deal with huge data, and java is capable in doing it.
