1. Date Format    coderanch.com

A Date object represents the actual date -- i.e., the time in UTC. It's only in rendering the Date as a String that the concept of a format is introduced. Beginners often make the same mistake with floating-point numbers. A float or double has some arbitrary number of decimal places -- i.e., 3.99999999654. It's only in rendering it as text that ...

Efficiency is overrated, I think. For most programs, IO/database operations are the slowest by far, and the speed of anything else is unimportant.

Why is it not working? How have you created the Calendar object you're getting the weekday from? Also, don't assume weekdays are 1-based or 0-based. Instead, use the constants to convert: int weekday = calendar.get(Calendar.DAY_OF_WEEK) - Calendar.SUNDAY + 1; Since Calendar.SUNDAY is guaranteed to be the lowest of these values (by the API), subtracting it from the weekday will guarantee a ...

Parsing a date string without knowing the format is impossible in general. Suppose you get the string "07/08/2009" - how can you see if this means 7 August 2009 (DD/MM/YYYY) or 8 July 2009 (MM/DD/YYYY)? You could do it by trying to parse a string with a different number of formats, but this will not solve the problem of ambiguous dates. ...

61. Unable to get Date instance in a particular format    coderanch.com

Date objects do not have a format by themselves. So you cannot "get a Date instance in a particular format". A Date object is nothing more than a number of milliseconds since 1 January 1970, 00:00:00 GMT. When you display a Date by calling toString() on it (explicitly or implicitly) as you are doing in line 9 of your code, then ...

First of all, let's make one thing clear: java.util.Date has no formatting, other than a simple one for debugging. To format a Date you must turn it into a String.
