The construction method of the thread class, the static block is called by which thread

The construction method of the thread class, the static block is called by the thread that the new thread class is on, and the code inside the Run method is called by the thread itself.

If you're confused by the above statement, let me give you an example, assuming Thread2 New in the Thread1,main function new Thread2, then:
(1) Thread2 constructor method, static block is called by main thread, Thread2 's Run () method is Thread2 call
(2) Thread1 construction method, static block is called by Thread2, Thread1 's Run () method is called by Thread1 itself

The construction method of the thread class, the static block is called by which thread
