Check if a given time lies between two times regardless of date

android, calendar, date, java, timespan

Solution

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);
    Calendar calendar3 = Calendar.getInstance();
    calendar3.setTime(d);
    calendar3.add(Calendar.DATE, 1);

    Date x = calendar3.getTime();
    if (x.after(calendar1.getTime()) && x.before(calendar2.getTime())) {
        //checkes whether the current time is between 14:49:00 and 20:11:13.
        System.out.println(true);
    }
} catch (ParseException e) {
    e.printStackTrace();
}

Problem

I have timespans: String time1 = 01:00:00 String time2 = 05:00:00 I want to check if time1 and time2 both lies between `20:11:13 and 14:49:00`. Actually, `01:00:00` is greater than `20:11:13` and less than `14:49:00` considering `20:11:13` is always less than `14:49:00`. This is given prerequisite. So what I want is, `20:11:13 < 01:00:00 < 14:49:00`. So I need something like that: ``` public void getTimeSpans() { boolean firstTime = false, secondTime = false; if(time1 > "20:11:13" && time1 < "14:49:00") { firstTime = true; } if(time2 > "20:11:13" && time2 < "14:49:00") { secondTime = true; } } ``` I know that this code does not give correct result as I am comparing the string objects. How to do that as they are the timespans but not the strings to compare?
