Do You REALLY Understand CompletableFuture In Java? 🤯
Ever wondered what actually happens inside CompletableFuture?
In this video, we break down its internal working step-by-step using a simple real-world example:
Why Future.get() blocks
Why CompletableFuture doesn't need get() to trigger the chain
What actually triggers thenAccept() and thenRun()
How completion of one stage triggers the next stage
What happens when you remove future.get()
The difference between starting the async task and waiting for its completion
By the end, you'll understand the core idea behind the CompletableFuture chain instead of just memorizing its APIs.
Perfect for Java interviews and real-world asynchronous programming.
