Question

Hi Guys & Gals,
I need a small help I need to know how to write a java program to run a executable file at a specified time? For example I need to start Editplus at 4.00Pm.

Hi You can use this program
For testing purpose, i have calculated scheduled time by adding 1 minute to the current time, see the bold line, you may change this
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;
public class ExecuteEXE extends TimerTask {
      * @param args
      public void run() {
              //TODO generate report
                //TODO generate report
                 Runtime r=Runtime.getRuntime();
                Process p=null;
                System.out.println("Executing ");
                try
             String s="c:\\programe files\\editplus\\editplus.exe"; // Change here accodingly
           //     String s="D:\\Timesheet.bat";
                 p=r.exec(s);
              catch(Exception e){
                System.out.println("error==="+e.getMessage());
                e.printStackTrace();
class MainApplication {
       public static void main(String[] args) {
         Timer timer  = new Timer();
       java.util.GregorianCalendar cal = new java.util.GregorianCalendar();
       cal.setTime(new Date());
          //adding a minute with current time for testing
          cal.add(java.util.GregorianCalendar.MINUTE,1);
          Date newd = cal.getTime();
          System.out.println("Current time "+new Date());
          System.out.println("Scheduled time "+newd);
        timer.schedule(new ExecuteEXE(),newd); // newd is the scheduled time
         System.out.println("Timer Started");
     }
