Question

java language question:

Write a thread that continuously prints a message every 100 milliseconds while it is still alive. The thread should be written in such a way that it can be terminated at any time by a control program (main).

Answer 1

-> For End Program press q and Enter
-> You can change delay time by changing the delay variable(Default 100 ms)
-> Don't Forget to check if the thread is null before call interrupt
RESULT:

CODE:

myThread.java

import java.util.Scanner;
import java.util.logging.Level;
import java.util.logging.Logger;

public class myThread {

    // Initilizing All Variables
    private static int delay = 100;
    private static Runnable r;
    private static Boolean stop = false;
    private static Thread t;
    private static Scanner scanner;

    //Main Method
    public static void main(String[] args) {

        // Creating Runnable to handle print process
        Runnable r = new Runnable() {
            @Override
            public void run() {
                while (!stop) {
                    System.out.println("Thread is Running");
                    // delaying Thread
                    try {
                        t.sleep(delay);
                    } catch (InterruptedException ex) {
                        Logger.getLogger(myThread.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
                // Stopping Thread
                if (t != null) {
                    t.interrupt();
                }
            }
        };

        //Creating Thread using Runnable
        Thread t = new Thread(r);
        t.start();

        scanner = new Scanner(System.in);
        // Loop for exit from Program
        while (true) {
            String val = scanner.next();
            // When Entered q Exit From Program
            if (val.equals("q")) {
                stop = true;
                break;
            }
        }
    }
