Introduction

CompletableFuture is a class in Java that helps write non-blocking, asynchronous code. It allows for chaining tasks, combining multiple asynchronous operations, and handling exceptions in a cleaner and more readable way.

---

Why Use CompletableFuture

• Non-blocking and asynchronous execution
• Simplifies handling of callbacks
• Combines dependent or independent tasks
• Provides better error handling with methods like exceptionally and handle

---

Key Methods and Concepts

Here are the must-know methods in CompletableFuture:

1. thenApply - Transform the result of a task.
2. thenCompose - Chain dependent tasks.
3. thenAccept - Consume the result without returning a new value.
4. thenRun - Run a task after completion without using the result.
5. Combining Tasks - Using methods like thenCombine, allOf, and anyOf.
6. Exception Handling - Handling errors with exceptionally and handle.
