Why Should You Be Learning Java?

If you look at the history of Java, you’ll see that it has been around for quite a while. Originally developed at Sun Microsystems in 1991, they wanted to develop a programming language for small devices like TVs, and VCRs. The goal was to make a portable small programming language which originally was known as AWK. It was released as Java in 1995

When Java was first released, its developers wrote a white paper justifying a new programming language, and in that white paper they described Java as simple object-oriented programming (OOP), portable, distributed and secure. To an extent these qualifiers correctly describe the programming language.

First of all, Java is simple, it is a simple programming language offering all the functionalities of the C++ language. The number of language constructs is small compared to most other programming languages. They decided to remove some of the features of C++, like pointers, structs, type def and define.

Secondly Java is an object-oriented language and is purely object oriented unlike C++ which only supports object orientation. Java works with its data as objects and with interfaces to these objects.
Java is considered a distributed programming language. It has extensive support for TCP/IP as well as have network capabilities.

It also contains library routines for HTTP, FTP etc.

Java is a secure language. It does not have low level functions and file access can be restricted through the program. When you run code, the interpreter verifies the bytecode and these features make Java more secure.

Conclusion

There are over a thousand courses for learning the Java programming language on the internet. However, these are some of those considered to be of the best online Java courses by expert instructors. Java is one of the popular programming languages and is the primary language for many developers. Also, the demand for Java developers continues to grow high.

Learning Java will help you in your career growth or carve you a career as a Java developer. Acquiring this skill, you will have enough opportunities to land yourself a job in Java development.
