Initially this language was called as "oak" later it was renamed as "java".Java was introduced in order to create a platform  independent language means we can execute the programs anywhere and on any operating system.So java is a platform independent language.

              Java adds both the features of c(POP) and c++(OOP) and it reduced the problems erased in both the languages like security,portability etc.,any way we will go through these topics  later

              By using Java we can create two types of programs known as applets and applications.An application is a program that runs on your computer and it is runs under the operating system of that computer.An applet is an application and it is transmitted over the internet and it is executed by a Java compatible web browser.It is downloaded like an image or like a video clip or like a sound file.

               Internet users can develop their websites using Java applets.Due to this reason Java is also known as internet language.
