• 11.
  Default Method Allowsfor extending an interface without breaking existing code As a consequence, allows multiple inheritance
• 12.
  Other Language Features Parameter name reflexion • Need to compile with -parameters option Improved type inference for generics
• 13.
  New Library Features Rehauled collections & Streams Date-Time Package Unsigned integer arithmetics
• 14.
  Streams Java 8provides functional-style operation on collections Provides sequential or parallel map-reduce transformations New package: java.util.stream
• 15.
  Date-Time Package Newpackage: java.time Can finally forget about java.util.Date and java.util.Calendar classes Rich and fluent set of classes Consistent design
