🚀 Java Lambda Expression Example – Math Operations

This project demonstrates how to use Java 8 Lambda Expressions with a functional interface to perform simple math operations like addition and subtraction.

📌 What is a Lambda Expression?

A Lambda Expression is a short block of code that takes in parameters and returns a value. It provides a clear and concise way to represent a method using ()-> {} syntax.

In Java, Lambda Expressions are often used with functional interfaces (interfaces with a single abstract method).

📝 Code Example @FunctionalInterface interface MathOperation { int operate(int a, int b); }

public class LambdaMath { public static void main(String[] args) { // Lambda for addition MathOperation add = (a, b) -> a + b;

    // Lambda for subtraction
    MathOperation sub = (a, b) -> a - b;

    // Direct usage
    System.out.println("Addition: " + add.operate(10, 5));      // 15
    System.out.println("Subtraction: " + sub.operate(10, 5));  // 5
}

}

📊 Output Addition: 15 Subtraction: 5.
