JAVA, Introduction Types, and More


Java was industrialized by “James Gosling” at Sun Microsystems -Inc.. in 1995, and later it was acquired by Oracle Corporation as a simple programming language. It is a simple programming language that makes writing, compiling, and also debugging programming easy. It helps to create reusable code and also modular programs.


It is a general-purpose, class-based, so, object-oriented programming language designed for having laser implementation dependencies. It is one of the fastest, most secure, and also most reliable programming languages most organizations prefer to build their project.

It is a simple programming language that is easy to learn and understand; however, the syntax based on c++. It also removed objects like explicit pointers, and operator overloading makes it easy to read and also write.
It uses a pattern, hence, which makes it more practical. It is an object which takes care of both behavior and data.


It is a secure programming language as it does not have clear indicators. So, It runs inside the virtual machine sandbox.

High -level usage

It means the developers designed the program for individuals are more in coding as ,they are compared to low level machines code.



It needs to be attentive to runtime, hence, which allows it to run on every operating system. It makes the arrangements slow for languages like C and C++.

Memory consumption:

It consumes more memory power since it runs on the virtual machine.


This language is costly due to its higher processing and memory requirements.
