What does start() function do in multithreading in Java? - GeeksforGeeks

We have discussed that Java threads are typically created using one of the two methods : (1) Extending thread class. (2) Implementing Runnable

In both the approaches, we override the run() function, but we start a thread by calling the start() function. So why don't we directly call the oveerridden run() function? Why always the start function is called to execute a thread?

What happens when a function is called?
When a function is called the following operations take place:

1. The arguments are evaluated.
2. A new stack frame is pushed into the call stack.
3. Parameters are initialized.
4. Method body is executed.
5. Value is retured and current stack frame is popped from the call stack.
