Examples of com.ibm.icu.text.DateIntervalFormat

com.ibm.icu.text.DateIntervalFormat

date interval object which the DateIntervalFormat formats on // and parses into DateInterval dtInterval = new DateInterval(1000*3600*24L, 1000*3600*24*2L); DateIntervalFormat dtIntervalFmt = DateIntervalFormat.getInstance( YEAR_MONTH_DAY, Locale("en", "GB", "")); StringBuffer str = new StringBuffer(""); FieldPosition pos = new FieldPosition(0); // formatting dtIntervalFmt.format(dtInterval, dateIntervalString, pos);

Code Sample: for powerful users who wants to use their own interval pattern

Fallback pattern is used when interval pattern is not found. // If the fall-back pattern is not set,  falls back to {date0} - {date1} if interval pattern is not found. dtitvinf.setFallbackIntervalPattern("{0} - {1}"); // Set above DateIntervalInfo object as the interval patterns of date interval formatter dtitvfmt.setDateIntervalInfo(dtitvinf); // Prepare to format pos = new FieldPosition(0); str = new StringBuffer(""); // The 2 calendars should be equivalent, otherwise,  IllegalArgumentException will be thrown by format() Calendar fromCalendar = (Calendar) dtfmt.getCalendar().clone(); Calendar toCalendar = (Calendar) dtfmt.getCalendar().clone(); fromCalendar.setTimeInMillis(....); toCalendar.setTimeInMillis(...); //Formatting given 2 calendars dtitvfmt.format(fromCalendar, toCalendar, str, pos);
