我有一个应用程序从用户那里获取开始和结束时间,并在(开始时间)开始特定进程运行到(结束时间),对于示例我使用 TimerTask 实用程序,以防它只从当前时间开始进程和运行到(结束时间)我无法设置开始时间我如何在java中commapare用户时间(开始时间)和系统时间
//my sample program
import java.sql.Date;
import java.util.Timer;
import java.util.TimerTask;
public class Main {
public static void main(String[] argv) throws Exception {
int numberOfMillisecondsInTheFuture=1000;
// start time= dynamically set by user
// end time =dynamically set by user
Date timeToRun = new Date(System.currentTimeMillis() + numberOfMillisecondsInTheFuture);//here is the problem.
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
//System.out.println("doing");
//doing some task not related to this question
}
}, timeToRun);
}
