  • Using lambda expressions
  • Understanding method and constructor references
  • Defining and using functional interfaces
  • Using sequential and parallel streams
  • Using the enhanced concurrency and collection APIs
  • Understanding Java 8 security features
  • Understanding additional API and language improvements
