A Nifty Guide on Java and its Growth

Java is a general purpose, object-oriented programming language that is widely used by professionals. It has been dominating industries since the 2000s. In this blog, we cover the basic features of Java and why it is essential to enroll for Java certification courses.

What is Java?

Java is a class-based object oriented programming language that is similar to C++. However, Java’s features are much more advanced and user-friendly. It can run on a variety of platforms and may be accessed for free. Some of the advantages of using Java are that you can write a code only once but use it multiple times in different platforms that support Java. Codes can be executed concurrently instead of sequentially. Java platforms enable users to develop powerful applications.


Java is a programming language that was developed by a team called the Green Team, in 1995. The members of the team included James Gosling, Mike Sheridian and many other distinguished professionals. It was developed for digital devices, like televisions and set-top boxes.

Current applications of Java:

Java in used in a variety of industries. Some of them are:

  • Banking and finance: Used for managing transactions
  • IT: Used for finding solutions to implementation dependency
  • Big data: Frameworks like Hadoop MapReduce are written using Java
  • Stock market: Used to construct algorithms that will tell companies what they should put their money in.
  • Scientific research: For handling large data sets
  • Retail: Billing applications are coded in Java

Features of Java:

  • Java has made object oriented programming much simpler for learners and users alike. It has eliminated complicated things like pointers, which are used in C++.
  • Portability: Codes written in one platform can be easily used in other platforms supporting Java.
  • Being object oriented, all operations are performed using the ‘’objects’’.
  • Security: Codes are converted to bytecodes post compilation and this cannot be read by humans. Hence, it can be used for tamper-free development of applications.
  • Dynamic: It can adapt to changing environments while reducing memory wastage.
  • Eliminates error by checking codes as they are run and compiled
  • JIT (Just-In-Time) compilers enable high performance.
