What is difference between Java SE and EE?

Question

Is there any different between Java SE and EE?

Answer 1

Additional to @Michael's answer: Java EE is not totally free. So check the EULAs before use.

Answer 2

Java SE implements the core functionalities for Java programming (basically all you'll ever use as an amateur/student/freelance). It includes the definitions of everything from primitive types to Objects and high level classes used for networking, i/o, GUI etc.
It also includes the developer kit, the virtual machine, development tools...

Java EE is built on SE (Java EE includes everything of SE), but it also implements some advanced network API for large-scale network applications.

TL;DR You don't need EE.
