λ Lambda Expressions in Java

Embrace Functional Programming in Java

Write concise, readable code with lambda expressions and functional interfaces

🎯 About

Lambda Expressions (Java 8) provide a clear and concise way to implement functional interfaces. Write less code, achieve more!

📝 Syntax

// No parameters
() -> System.out.println("Hello!")

// One parameter
x -> x * x

// Multiple parameters  
(x, y) -> x + y

📚 Examples

// Traditional vs Lambda
Runnable r1 = new Runnable() {
    public void run() { System.out.println("Old way"); }
};

Runnable r2 = () -> System.out.println("Lambda way!");

// Collections
List<String> names = Arrays.asList("Alice", "Bob");
names.forEach(name -> System.out.println(name));
names.forEach(System.out::println); // Method reference

🔧 Functional Interfaces

Interface	Method	Purpose
Consumer	accept(T)	Takes input, no output
Supplier	get()	No input, returns output
Function	apply(T)	Input to output
Predicate	test(T)	Returns boolean
