every constructor requires the date information (year, month, and day) in the time information ). If you want to say p.m., you must point out the date.Similarly, each gregoriancalendar constructor creates an object in milliseconds. Therefore, if your constructor only provides the year, month, day parameter, then the hour, minute, second, and millisecond values will be set to 0.Dateformat and timeYou can use the static method getdatetimeinstance (INT datestyle, int

First introduce the date formatting: (not too many OH)Jstl formatted date (localized)Similar to digital and currency formatting, the localized environment also affects how dates and times are generated.properties of the Type: can be time,date , or both. Controls whether only the time is generated, the date is generated, or the time date is generated. Datestyle: can be short , medium, long or full (default). Controls the specific format used for the print date.
