Question

I have a batch file in my C: drive named abc.bat which I want to execute every two minutes. I have to do this with Java. I need to use the TimerTask class. Below is my current code:

import java.util.TimerTask;
import java.util.Date;
import java.util.Timer;


// Create a class extends with TimerTask
public class ScheduledTask extends TimerTask {

    // Add your task here
    public void run() {
        Runtime.getRuntime().exec("cmd.exe /c start abc.bat");
    }
}

//Main class
public class SchedulerMain {
    public static void main(String args[]) throws InterruptedException {

        Timer time = new Timer(); // Instantiate Timer Object
        ScheduledTask st = new ScheduledTask(); // Instantiate SheduledTask class
        time.schedule(task, now ,TimeUnit.SECONDS.toMillis(2));

    }
}

Answer 1

If your abc.bat file is located in c:\ then use

Runtime.getRuntime().exec("cmd.exe /c start c:\\abc.bat");

Also you need to create

java.util.Date now = new java.util.Date(); 

if you want to use it in time.schedule(task, now ,TimeUnit.SECONDS.toMillis(2));

or just use time.schedule(task, new java.util.Date() ,TimeUnit.SECONDS.toMillis(2));
