What is the difference between start() method and run() method in Java multithreading?

• In the case of t.start() a new thread will be created which is responsible for the execution of run () method.

• But, in the case of t.run() a new thread will not be created and run() will be executed just like a normal method called by the main method.

• Hence, in the previous program if we replace t.start() with t.run() then out is as follow:

• Child thread is running(10 times)

• the main thread is running(10 times)

• This total output produced by an only main thread.
