Java-Lamda Expressions

1. Java Lambda Expressions

2. Java Lambda Expressions
Lambda Expressions were added in Java 8.
A lambda expression is a short block of code
which takes in parameters and returns a value.
Lambda expressions are similar to methods,
but they do not need a name and they can be
implemented right in the body of a method.

3. Java Lambda Expressions
Java Lambda Expressions are Java’s first step into
Functional Programming.
It is an Anonymous function that doesn’t have a
name and doesn’t belong to any class.
It Provides a clear and concise way to represent a
method interface via an expression
It provides the implementation of a Functional
Interface & Simplifies the software development.

4. Syntax
The simplest lambda expression
contains a single parameter and an
expression:
parameter -> expression

5. Syntax
To use more than one parameter, wrap
them in parentheses:
(parameter1, parameter2) -> expression

6. FUNCTIONAL INTERFACE

7. Functional Interface
Functional Interface is an interface
that contains exactly one abstract
method.
It can have any number of default or
static methods along with object class
methods.
Java provides pre-defined functional
interfaces to deal with the functional
programming.
Runnable, ActionListener,
Comparable are some of the

8. Here are just a few of the key
benefits to using lambda
expressions in Java:
Conciseness.
Reduction in code bloat.
Readability.
Elimination of shadow variables.
Encouragement of functional programming.
Code reuse.
Enhanced iterative syntax.
Simplified variable scope.
