Lambda Expressions are a way of representing anonymous functions in Java. They allow you to use functionality as an argument to a method or create simple functions with minimal boilerplate code. The language shifted to functional programming paradigms with Java 8. Java Classes in Pune

In the past, to pass behavior to a method, you would have to create an interface that contained a single abstract (SAM) method, then instantiate a class of this interface to implement the method. This led to a lot of verbose code, particularly for simple operations. Lambda Expressions simplifies this process, allowing you directly express single-method interfaces using a compact syntax.

The syntax for a lambda is composed of an arrow (->,, parameters and a body. The parameters are enclosed (if any) in parentheses, and the body is an expression or block of code enclosed within curly braces. The compiler will infer the type of parameter, but you can specify it explicitly if necessary.
