Lambdas y Streams Practica

Concept

lambda: A lambda expression (also called an anonymous function) is a function without a name identifier. For example, (int x, int y) -> x + y is a lambda expression that takes two integer args and returns their sum. Lambda expressions can be conveniently passed as parameters or can be returned from functions, and are the hallmark of functional languages. Some object-oriented languages such as Smalltalk, Scala, JavaScript, and Ruby supported lambda expressions from the first release.

streams: are an update to the Java API(JDK 8) that let you manipulate collections of data in a declarative way (you express a query rather than code an ad hoc implementation for it). For now you can think of them as fancy iterators over a collection of data. In addition, streams can be processed in parallel transparently, without you having to write any multithreaded code!.

MeetUp

Today, I attend to a meetup from the great group medellin-java on meetups platform, in the talk to give, access to the repo for face this little exercises for practice and understand how apply lambdas expression for get cleaner and readable code a lase remove a lot of verbose code, we have to carry when we implement anonymous classes comparator, for filtering and behaviors another context that until java JDK 7, you must create for get your code working, java 8 updates with new statics methods and default methods on interfaces, its allows currently get cleaner and short useful codes, integrating OOP and functional programming and all in java world
