Java 8 Features:

1. Functional Interfaces:

Functional interfaces are like blueprints for functions in Java 8. They’re crucial because they set the stage for lambda expressions and other cool stuff in Java 8. We’ll learn how to make our own functional interfaces, which is handy for tailoring them to our specific needs.

2. Lambda Expressions:

Lambda expressions are like shortcuts for writing code in Java. They’re super helpful because they let us write less code while still getting stuff done. We’ll dive into how to use lambda expressions to make our code cleaner and easier to understand.

3. Stream API:

Imagine a magic wand for working with collections in Java—that’s the Stream API. It makes doing cool stuff with lists and arrays way easier, like filtering out certain items or transforming data. We’ll learn all about streams and how they make our lives as programmers much simpler.

4. Default Methods:

Default methods are like extra features added to interfaces in Java 8. They’re handy because they let us update interfaces without breaking existing code. We’ll explore how default methods work and how they help us evolve our code over time.

5. Optional:

Null values can be a pain, but the Optional class in Java 8 is like a superhero that swoops in to save the day. It helps us handle null values more safely, reducing the chance of errors in our code. We’ll find out how Optional works and why it’s so awesome.

6. Method References:

Method references are shortcuts for referring to methods or constructors in Java 8. They’re like little tricks that make our code cleaner and more readable. We’ll learn how to use method references to simplify our code and make it easier to follow.

7. CompletableFuture:

CompletableFuture is like a time machine for handling tasks in Java. It lets us do things asynchronously, which means we can multitask without slowing down our programs. We’ll see how CompletableFuture works and how it helps us build faster and more responsive applications.

8. Date-Time API:

The Date-Time API in Java 8 is like a Swiss army knife for working with dates and times. It’s got all sorts of tools for doing things like calculating durations or figuring out what day of the week it is. We’ll explore the Date-Time API and how it makes working with dates and times a breeze.
