Question
Which method is called when a thread starts executing?
Solution
The method that is called when a thread starts executing is the run() method. Here are the steps that usually happen:
- An instance of a class is created that implements the
Runnableinterface or extends theThreadclass. - The
run()method is overridden with the code that is needed to be executed in a separate thread. - An instance of the
Threadclass is created and the object from step 1 is passed as an argument to the constructor. - The
start()method is called on theThreadinstance. This method is responsible for creating a new thread and calling therun()method on theRunnableobject orThreadsubclass.
It's important to note that calling the run() method directly will not create a new thread and the code will be executed in the current thread.
