During Java One you can learn a lot directly from the experts and you can choose from 50 different sessions, multiple demos, keynotes, hands on labs (practical labs) which will cover following topics :

  • Constructing modern applications using Java SE
  • Creating rich and immersive client-side solutions using JavaFX
  • Building mobile and embedded Java applications targeting next-generation smart devices
  • Composing sophisticated Java EE–based enterprise solutions
  • Developing with the latest Oracle database technology
  • Building and deploying business applications in the cloud securely and seamlessly

I am definitely going to attend the Java One again. Last time I had a chance to help people at NetBeans Booth, thanks to Sharat Chander, Ashvin Rao and Java One Team for that great favor. I will love to host the NetBeans Booth again this time to help people. I am also working on book covering NetBeans and Java.
