This repository contains the code and resources for Sprint 1, which covers the following topics:

• Functional Interface
• Lambda Expression
• Inbuilt Functional Interfaces in Java
• Collections Framework Problems

Description: This project addresses a specific problem related to functional interfaces. It demonstrates how to implement and utilize them effectively. 💡

Solution:

• What is Functional Programming and Functional Interface ❓
• Implementations of Functional Interfaces:
  • Predicate ✔️
  • Consumer 🖨️
  • Supplier 🛍️
  • Function<String, Product> ↔️

Description: In this project, we dive into lambda expressions and explore their practical applications. It showcases various examples to illustrate their usage. 📝

Solution:

• Bean classes: Student and Employee 📚
• List of Student objects 📋
• Transformation of Students to Employees using Stream API and map function 🔄
• Sorting Employees by salary in descending order using Lambda Expression 📉
• Printing both Employee's List and Original Student's List using Lambda Expression 🖨️

Description: The Problem 3 project focuses on using stream API and lambda expressions to process a list of Student names. ✨

Solution:

• Create a List of 10 Student names using stream API 📝
• Filter and transform names with even length to uppercase ✅
• Sort the transformed List in descending order using Lambda Expression 📉
• Print both original and transformed List using Lambda Expressions 🖨️

Description: This project explains the features of the Stream API in Java and discusses some of the intermediate and terminal methods of the Stream object. 🌊

Solution:

• Features of Stream API ✨
• Intermediate methods example ⚙️
• Terminal methods example 🏁

Description: The Problem 5 project explains the concept of method reference and demonstrates how to refer to static methods, non-static methods, and constructors using method references. 🔗

Solution:

• Explanation of Method Reference ❓
• Static method reference example ⚡
• Non-static method reference example 🏃‍♀️
• Constructor reference example 🏭

Description: This project focuses on implementing a class named GroceryItems with customized sorting using the Comparator interface. 🛒

Solution:

• GroceryItems class with price, name, and usedFrequency data members 📦
• Definition of Comparator to sort GroceryItems 🔀
• Storing objects of GroceryItems in TreeSet with natural order and custom order defined by Comparator 🌟
