Lambda expressions are known to many of us who have worked on advanced languages like Scala. The term “lambda” has its origin in Lambda calculus that uses the Greek letter lambda (λ) to denote afunction abstraction. Lambda expressions were introduced to Java as part ofJava 8release. 1. ...
Ever since I heard Java 8 is going to support lambda expressions (aka closures), I was very enthusiastic to spice my code with such a decent and concise functional element. Most developers extensively use Anonymous Inner Classes for event handlers, comparators, basic thread/runnable implementations,...
Using a Lambda Expression in a Function Example You can use lambda expressions in the body of a function. The lambda expression can access any function or data member that the enclosing function can access. You can explicitly or implicitly capture thethispointer to provide access to functions and...
Modern Java features, such as lambda expressions, method references, and functional programming, can be leveraged to simplify the implementation of design patterns. For example, the Strategy pattern can be implemented more concisely using lambda expressions, making the code more expressive and easier to...

Java Predicate is one of the new packages and utility being introduced in java 8, which is very flexible with the lambda expressions and helps the programmers create a neat and clean enhanced code for reference and understanding. A predicate with the values helps in the evaluation of the condit...
