In this article History of Java we give the information about the Java language was created in 1991 by James Gosling and his team at Sun Microsystems. It is used to develop advanced and secure applications, websites, mobile applications and desktop applications etc.
Introduction to Java:-
Java is a programming language used for software development. It is used to develop advanced and secure applications, websites, mobile applications and desktop applications etc. This programming language is of high level which uses the principles of Object-Oriented Programming. This makes it a language that can be used for a wide variety of tasks.
Software developed by Java requires a Java Virtual Machine to operate. Java virtual machine is a software that systematically interprets Java code so that it can run on all platforms without any problem.
In Java, source code is compiled into byte code, whereas in other languages, source code is compiled into machine code.
History of Java:
The Java language was created in 1991 by James Gosling and his team at Sun Microsystems. This team is also called Green Team which included James Gosling, Mike Sheridan, and Patrick Naughton. All of them work in Sun Microsystem.
Sun Microsystem used to make software for its clients, but they had to do different coding to run the same software on different machines, in view of which they thought of creating Java language. Which is platform independent and can be easily run on any platform.
Java language was developed as a project to create a language for digital devices like set-top boxes, televisions.
Nowadays, Java is used for making internet programming, mobile devices, games etc.
Java is the most popular and widely used programming language in the world today. Java is a portable, secure and robust, programming language.
The Java language was developed as a project in June 1991 by a team working at Sun Microsystem called Green Team.
The real name of Java was Oak. Oak is a symbol of strength and it was also a national tree in many countries like U.S.A., France, Germany, Romania.
At that time, a company with the name Oak was already registered, so there was discussion about changing its name, but it was not possible to decide on a name, then one day when the Oak team was sitting where they were drinking coffee, there was Indonation coffee which was indonescence. Coffee was made from a substance called java, hence it was named java.
In 1995, its name was changed from Oak to Java. The first version of Java (Java 1.0) was publicly released in 1995.
