Think of an unlimited grid with just a left edge. Each event is one cell wide, and the height and vertical position is fixed based on starting and ending times. Try to place each event in a column as far left as possible, without it intersecting any earlier event in that column. Then, when each … Read more
You can use the Calendar class in order to check. For example: try { String string1 = “20:11:13”; Date time1 = new SimpleDateFormat(“HH:mm:ss”).parse(string1); Calendar calendar1 = Calendar.getInstance(); calendar1.setTime(time1); calendar1.add(Calendar.DATE, 1); String string2 = “14:49:00”; Date time2 = new SimpleDateFormat(“HH:mm:ss”).parse(string2); Calendar calendar2 = Calendar.getInstance(); calendar2.setTime(time2); calendar2.add(Calendar.DATE, 1); String someRandomTime = “01:00:00”; Date d = new SimpleDateFormat(“HH:mm:ss”).parse(someRandomTime); … Read more
What you could do is creating an instance of a GregorianCalendar and then set the Date as a start time: Date date; Calendar myCal = new GregorianCalendar(); myCal.setTime(date); However, another approach is to not use Date at all. You could use an approach like this: private Calendar startTime; private long duration; private long startNanos; //Nano-second … Read more
To save and load accurate date, you could use the long (number) representation of a Date object. Example: //getting the current time in milliseconds, and creating a Date object from it: Date date = new Date(System.currentTimeMillis()); //or simply new Date(); //converting it back to a milliseconds representation: long millis = date.getTime(); You can use this … Read more
Try this: Calendar cal = new GregorianCalendar(); SimpleDateFormat dateFormat = new SimpleDateFormat(“dd-MM-yyyy”); dateFormat.setTimeZone(cal.getTimeZone()); System.out.println(dateFormat.format(cal.getTime()));
