Java Background Time Calculation

Converts milliseconds to days and seconds

public static void Main (string[] args) {
Date date = new Date ();
System.out.println (Date.gettime ());
Long a = Date.gettime ();

Date date1 = new Date (a);
SimpleDateFormat SDF = new SimpleDateFormat ("Yyyy-mm-dd hh:mm:ss");
String strdate = Sdf.format (date1);

System.out.println (strdate);

}

Compare two times the size of a string into a time date type

public static void Main (string[] args) throws ParseException {
Date date = new Date ();
String strdate = "2016-03-02 22:12:11";
SimpleDateFormat format = new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");
Date date1 = Format.parse (strdate);
if (Date.gettime () > Date1.gettime ())
System.out.println ("Now Time is big");
Else
System.out.println ("String time is large");
}

The current time plus one day, calculate the time to add subtraction

public static void Main (string[] args) throws ParseException {

SimpleDateFormat SF = new SimpleDateFormat ("Yyyy-mm-dd");
Calendar C = calendar.getinstance ();
System.out.println ("Current Time:" +sf.format (C.gettime ()));

C.add (Calendar.day_of_month, 1);
System.out.println ("Add Day after Date:" +sf.format (C.gettime ()));
}

SQL for determining the time-date size in MyBatis
