从另一个线程调用线程的方法是否会暂停该线程的执行？

Question

Say I call a thread's method from inside another thread as such

public static void main(String[] args)
{
    //do something
    TestThread thread = new TestThread();
    thread.start();
    thread.doSomething();
    //Part A
}

class TestThread extends Thread
{
   public void run()
   {
       //do something
   }

    public void doSomething()
    {
        //Do something
    }
}

Will the program do everything in the doSomething() method before moving onto partA or will it start running the doSomething() method then move straight onto part A?
I'm making an application with a server serving multiple clients and want the server to be able to quickly move through the requests, so it should be once it is sent it moves on rather than waiting for the client to process the instruction.

No. The main thread will run doSomething() while the thread -thread will be running run() as usual.

Just because doSomething() is in a class that extends Thread doesn't mean that there's anything special about it as a method.
