  • Create high-performance multi-threaded applications

Target Audience:

  • Java EE Developer
  • Developer
  • Java Developer

Prior knowledge

  • Attendance or Knowledge of Java SE 8 Fundamentals

 

 

Those delegates who are attending via either virtual or extended classroom will be required to provide either dual monitors or single monitor plus a tablet device.

 

Objectives:

At the end of this course you will be able to:
