Question

I have two String variables – time1 and time2. Both contain value in the format HH:MM. How can I check:

1. If the current time is within
   time1 and time2?
2. time1 will happen in the nearest
   hour?

Upd.
I’ve implemented the following to convert time1 to Date format. But it uses depreciated methods:

Date clTime1 = new Date();

SimpleDateFormat timeParser = new SimpleDateFormat("HH:mm", Locale.US);
try {
  clTime1 = timeParser.parse(time1);
} catch (ParseException e) {
}

Calendar now = Calendar.getInstance();
clTime1.setYear(now.get(Calendar.YEAR) - 1900);
clTime1.setMonth(now.get(Calendar.MONTH));
clTime1.setDate(now.get(Calendar.DAY_OF_MONTH));
System.out.println(clTime1.toString());

Answer 1

• Convert the two strings to Date
  objects (which are also time objects)
  Create a new Date object.
• This will
  contain the current time.
• Use the
  Date.before() and Date.after() methods to determine if
  you are in the time interval.

EDIT: You should be able to use this directly (and no deprecated methods)

public static final String inputFormat = "HH:mm";

private Date date;
private Date dateCompareOne;
private Date dateCompareTwo;

private String compareStringOne = "9:45";
private String compareStringTwo = "1:45";

SimpleDateFormat inputParser = new SimpleDateFormat(inputFormat, Locale.US);

private void compareDates(){
    Calendar now = Calendar.getInstance();

    int hour = now.get(Calendar.HOUR);
    int minute = now.get(Calendar.MINUTE);

    date = parseDate(hour + ":" + minute);
    dateCompareOne = parseDate(compareStringOne);
    dateCompareTwo = parseDate(compareStringTwo);

    if ( dateCompareOne.before( date ) && dateCompareTwo.after(date)) {
        //yada yada
    }
}

private Date parseDate(String date) {

    try {
        return inputParser.parse(date);
    } catch (java.text.ParseException e) {
        return new Date(0);
    }
}
