What is Java?
Java can be written only once and it is a run anywhere programming language developed by Sun Microsystems. Being similar to C and C++, it has some features that are similar but Java is a lot easier. It is also Object-Oriented Programming Language that is based on the Object-Oriented Programming System (OOPS).
You might have noticed sometimes that when you open a website or an application, it demands Java to be installed, it is because some of the applications and website would not work until Java is installed.
It is fast, secure, and reliable. Also, Java is a Write once and Run Everywhere independent programming language!
Java has been very popular and has dominated the world since early 2000. You might remember studying Java in your Computer Classes when you were in school. Do you remember any of the information? Well, if you don't, we have got you covered!

History of Java
It is a programming language developed by James Gosling with other members called the “Green Team” in 1995 for Sun Microsystems for devices like a set-top box, television, etc. later it was incorporated by Netscape. At first, java was named “Green talk” which has the file extension as .gt. It was then named Oak and was taken up as a part of the Green project.
Time magazine called Java as one of the best products of 1995.
Right now, Java is used for internet programming, mobile devices, games, e-business solutions, etc.
