Want to create a thread in Java without extending `Thread`?

I explained it simply in my latest ByteCraft article.

Stack or Heap? 🤔

`User user = new User();`

Where does `user` go?
Where does the object go?

Understanding Stack vs Heap helps explain:

🔹 GC
🔹 Memory leaks
🔹 StackOverflowError
🔹 OutOfMemoryError

I explained it simply 👇

Heap, Stack, Method Area… 😵‍💫

Where does Java actually store data?

The Heap stores objects. Each thread has its own Stack. The Method Area stores class information.

I explained JVM memory with examples and common errors 👇

Java has Garbage Collection, but it doesn't fix every memory problem. 😄

GC checks whether objects are still reachable. If not, they become eligible for collection.

I explained Heap, GC Roots, G1, ZGC & memory leaks.

*Why is `String` immutable in Java? 🤔*

How do you make your own class immutable?

I explained immutable objects, defensive copying, `String`, thread safety, `HashMap` keys, and common interview questions in my new ByteCraft article.
