James Gosling, Patrick Naughton Chrisworth, Rd Frank, and Mike Sheridan created Java in 1991. Java is mainly related to C++ but the core of the language is derived from C. Initially, its name was Oak, but in 1995 it was changed from Oak to Java. It was publicly announced only in the year 1995.
The main reason behind its creation was to make a platform-independent programming language. It is often used to develop software for electronic devices. Java was most affected by a network called an applet, which is a type of Java program that was created to broadcast over the Internet. Java also solves the problems of security and portability of the second language used.
You might have also come across different versions of java. Isn’t it? But do you know what things differ in their new versions? If not, you are there at the right place. Stay tuned and go through the article carefully to get complete details.
