Can the Thread run method be overloaded?

Yes. You may overload the run method. However, The overloaded run method will be ignored by the Thread start method and it always starts the run method with no args.

public class OverloadedRunTest extends Thread {

	public static void main(String[] args) {
		OverloadedRunTest ft1 = new OverloadedRunTest();
		ft1.start(); // Separate call stack
		ft1.run("Hello"); // same call stack
	}

	public void run() {

		System.out.println("Thread is running");
		run("With parameter");
	}

	public void run(String s) {
		System.out.println("Overloaded Thread is running " + s + " " + Thread.currentThread().getName());
	}
}
