• Interviewer: Create an empty class called MyThreadParent.

public class Main {
    public static void main(String[] args) {
        Thread thread = new Thread(new MyThread());
        thread.start();
    }
}

class MyThreadParent {}

class MyThread extends MyThreadParent implements Runnable {
    @Override

• Interviewer: What are commonly used Thread class methods?

 

You:

• isAlive(): Tests if the thread is alive.
• yield(): Causes the currently executing thread object to temporarily pause and allow other threads to execute.
• join(): Waits for a thread to die.
