Introduction to Functional Programming in Java 8

Using Java 8’s lambda expressions we can do the same thing by creating a stream of the elements in the ArrayList and then filtering them This is accomplished through a sequence of function calls: nums stream() filter((Double val) -> val > 50) forEach((Double val) -> System out println(val)); For readability purposes it is common to put each function call on a separate line: nums stream

lambda’s argument is inferred to be of type Integer Runnable greeter = -> System out println("Hi " + name); •Example: Runnable We are assigning a lambda to a variable of type Runnable , so that is the expected type for the lambda Runnable has a function void run() , so the lambda expression must not take any arguments

Performance of Lambda Expressions in Java 8

are lambda expressions in Java 8 faster than non-lambda expressions at accomplishing the same tasks 1 2 Motivation Our motivation for this work came from Oracle’s claim that the use of lambda expressions would result in more efficient code [1] We were interested in determining if there were advantages to using lambda expressions beyond their obvious conciseness Considering Oracle claimed

Tutorial - Angelika Langer

lambda (short for: lambda expression) stems from Lambda calculus, which is a theoretical framework for describing functions and their evaluation Rather than delving into the theoretical background let us keep it simple: a lambda expression denotes a piece of functionality Here is an example of a lambda expression in Java: (int x) -> { return
