# Lambda Expressions in Java () -> {}
## What are Lambda Expressions? 🤔
Lambda expressions were introduced in Java 8 as a way to write more concise and functional-style code. They provide a way to pass behavior as an argument to a method or constructor, without the need for creating anonymous inner classes.
Lambda expressions are especially useful when working with functional interfaces, which are interfaces that have only one abstract method. They allow you to express instances of these interfaces more compactly and enhance readability.
Java lambda expression is treated as a function, so compiler does not create .class file.
# Why use Lambda Expression
1. To provide the implementation of Functional interface.
2. Less coding.
# Java Lambda Expression Syntax
**(argument-list) -> {body}**
**1) Argument-list**: It can be empty or non-empty as well.
**2) Arrow-token**: It is used to link arguments-list and body of expression.
**3) Body:** It contains expressions and statements for lambda expression.
# No Parameter Syntax
```
() -> {
//Body of no parameter lambda
}
```
# One Parameter Syntax
```
(p1) -> {
//Body of single parameter lambda
}
```
# Two Parameter Syntax
```
(p1,p2) -> {
//Body of multiple parameter lambda
}
```
# Lambda Expression in Java
🔧 This GitHub repository contains a simple project that demonstrates the implementation of lambda expressions in Java.
