Java 8

Lambda Expressions : Lambda expressions are a new and important feature included in Java SE 8. They provide a clear and concise way to represent one method interface using an expression. Lambda expressions also improve the Collection libraries making it easier to iterate through, filter, and extract data from a Collection In addition, new concurrency features improve performance in multicore environments. Why Lambdas? A lambda expression is a block of code that you can pass around so it can be executed later, just once or multiple times. Syntax of Lambda Expressions A lambda expression consists of the following: A comma-separated list of formal parameters enclosed in parentheses The arrow token,  -> A body, which consists of a single expression or a statement block. Syantax Structure : (arg1, arg2...) -> { body } (type1 arg1, type2 arg2...) -> { body } Example : ( int a ,...

  Lambda expressions Lambda Expressions   enable you to encapsulate a single unit of behavior and pass it to other code. You can use a lambda expressions if you want a certain action performed on each element of a collection, when a process is completed, or when a process encounters an error. Parallel operations With the addition of Lambda expressions to arrays operations, Java introduced a key concept into the language of internal iteration. Essentially as developers we’re used to use loop operations as one of the most basic programming idioms, right up there with if and else. The introduction of Lambda expressions turned that paradigm around with the actual iteration over a collection over which a Lambda function is invoked is carried out by the core library. You can think of this as an extension of iterators where the actual operation of extracting the next item from a collection on which to operate is carried out by an iterator. An exciting possibil...
