Lambda

Lambda - Overview

• Define and write functional interfaces and describe the interfaces of the java.util.function package
• Describe a lambda expression; refactor the code that uses an anonymous inner class to use a lambda expression; describe type inference and target typing
• Develop code that uses the built-in interfaces included in the java.util.function package, such as Function, Consumer, Supplier, UnaryOperator, Predicate, and Optional APIs, including the primitive and binary variations of the interfaces
• Develop code that uses a method reference, including refactoring a lambda expression to a method reference
