  • Java Bean
  • Java persistence API
  • Java Transaction API
  • Java Servlet
  • Web Socket
  • Java Server Faces
  • Unified Expression Language
  • RESTful Web Services
  • JSON Processing
  • JSON Binding

Java ME
Lastly, we have a java micro edition. This edition is used to write Java code on set-top boxes, gaming consoles, mobile phones, handheld devices, and so on.
