BCA504 JAVA PROGRAMMING Mr. Trivarna Kandlur Assistant Professor Department of Computer Science Dr. B.B. Hegde First Grade College Kundapura
JAVA Java was conceived by James Gosling at Sun Microsystems in 1991. This language was initially called Oak but was renamed Java in 1995. Java is a Object Oriented(OOP) Programming language
It is used for: Mobile applications (specially Android apps) Desktop applications Web applications Web servers and application servers Games Database connection
Why Use Java? Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.) It is one of the most popular programming language in the world It is easy to learn and simple to use It is open-source and free It is secure, fast and powerful It has a huge community support (tens of millions of developers) Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs
