Java - Running a statement during specific periods of time

I'm trying to create an if/then statement in which the contents can only be run if it is executed during a specific time period.

I want to set a variable to a specific time, and another variable to a number (which will be minutes)

If the system time is in between the variable time and the number of minutes, then do nothing. Else, do something.

For example...
If my variable time is 23:45 and my minuted is 15, the "then" would not occur if executed between 23:45 and 24:00.

TIA

Use the Calendar class to create your start and end times. e.g.

Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, hour);
c.set(Calendar.MINUTE, minute);
Date start = c.getTime().getTime();
c.add(Calendar.MINUTE, minutesDelta);
Date end = c.getTime().getTime();
Date now = new Date();
if(now.after(start) && now.before(end)) {
   // Do it
}

Type mismatch converting long to date on start and end with the below code

Calendar c = Calendar.getInstance();
		int hour = Integer.parseInt(getConfigProperty("StopProcessHour", false));
		int minute = Integer.parseInt(getConfigProperty("StopProcessMin", false));
		c.set(Calendar.HOUR_OF_DAY, hour);
		c.set(Calendar.MINUTE, minute);
		Date start = c.getTime().getTime();
		int minutesDelta;
		c.add(Calendar.MINUTE, minutesDelta);
		Date end = c.getTime().getTime();
		Date now = new Date();
		if(now.after(start) && now.before(end)) {
		   // Do it
		}

You didn't initialize 'minutesDelta'...

Same error with this...

Calendar c = Calendar.getInstance();
		int hour = Integer.parseInt(getConfigProperty("StopProcessHour", false));
		int minute = Integer.parseInt(getConfigProperty("StopProcessMin", false));
		c.set(Calendar.HOUR_OF_DAY, hour);
		c.set(Calendar.MINUTE, minute);
		Date start = c.getTime().getTime();
		int minutesDelta = Integer.parseInt(getConfigProperty("SpecificMinutes", false));
		c.add(Calendar.MINUTE, minutesDelta);
		Date end = c.getTime().getTime();
		Date now = new Date();
		if(now.after(start) && now.before(end)) {
		   // Do it
		}

Can you please post your exact error message? What happens when you temporarily hard-code the int values?
