πŸš€ Why Prefer Method References Over Lambda Expressions?

Java lambda expressions simplify functional programming, but method references make the code even cleaner and more readable.

❌ Lambda expressions can be verbose β€” Too many unnecessary boilerplate elements.
❌ Less readable β€” Complex lambdas reduce clarity.
❌ Repetitive code β€” Often, lambdas just call existing methods.

πŸ’‘ Solution? Method references (::) replace simple lambdas with a more compact and readable syntax.

πŸ“Œ In this article, you’ll learn:
βœ… The difference between lambda expressions and method references.
βœ… When to use method references instead of lambdas.
βœ… Best practices with real-world examples.

πŸ” The Problem: Verbose Lambda Expressions

❌ Using a Lambda Instead of a Method Reference

import java.util.List;

public class LambdaExample {
public static void main(String[] args) {
List<String> names = List.of("Amit", "Raj", "Neha");

// ❌ Using a lambda to print each name
names.forEach(name -> System.out.println(name));
}
}

πŸ“Œ Problems:
❌ Redundant lambda syntax β€” Just calling an existing method (System.out.println).
❌ Less readable – Verbose code makes it harder to understand.

πŸš€ Solution? Replace it with a method reference!

βœ… Solution: Using Method References for Readability

βœ” Replacing Lambda with a Method Reference

import java.util.List;

public class MethodReferenceExample {
public static void main(String[] args) {
List<String> names = List.of("Amit", "Raj", "Neha");

// βœ… Using a method reference (shorter and cleaner)…
