How to format date in string like "December 31st 2000" in Java

Question

I tried using the SimpleDateFormat class to do this, but I did not find any options that put "st" after the day. I could only get "December 31, 2000"

How to format as "December 31st, 2000. I have a date in milliseconds.

Is there any API in java that allows us to format the date this way?

Answer 1

Simple function with switch enclosure, do it

 Public String getDateSuffix( int day) { switch (day) { case 1: case 21: case 31: return ("st"); case 2: case 22: return ("nd"); case 3: case 23: return ("rd"); default: return ("th"); } } 

Answer 2

The little function below will return the suffix String . (Stolen from this answer ).

 String getDayOfMonthSuffix(final int n) { if (n < 1 || n > 31) { throw new IllegalArgumentException("Illegal day of month"); } if (n >= 11 && n <= 13) { return "th"; } switch (n % 10) { case 1: return "st"; case 2: return "nd"; case 3: return "rd"; default: return "th"; } } 

Then all you have to do is something like:

 SimpleDateFormat dd = new SimpleDateFormat("dd"); SimpleDateFormat mmyyyy = new SimpleDateFormat("MMM, yyyy"); String formattedDate = dd.format(date) + getDayOfMonthSuffix(date.get(Calendar.DAY_OF_MONTH)) + " " + mmyyyy.format(date); 

Answer 3

I replied in a comment, but I decided that I could refuse the code.

 /** * Returns the appropriate suffix from th, nd or rd * @param cal * @return */ public static String dateSuffix(final Calendar cal) { final int date = cal.get(Calendar.DATE); switch (date % 10) { case 1: if (date != 11) { return "st"; } break; case 2: if (date != 12) { return "nd"; } break; case 3: if (date != 13) { return "rd"; } break; } return "th"; } 

Using:

 SimpleDateFormat sdf = new SimpleDateFormat("d'%s' MMM, yyyy"); String myDate = String.format(sdf.format(date), Util.dateSuffix(date)); 

Answer 4

This might be a little shorter:

 String getDayOfMonthSuffix(final int n) { if (n < 1 || n > 31) { throw new IllegalArgumentException("Illegal day of month"); } final String[] SUFFIX = new String[] { "th", "st", "nd", "rd" }; return (n >= 11 && n <= 13) || (n % 10 > 3) ? SUFFIX[0] : SUFFIX[n % 10]; } 

Answer 5

You can use an array of values.

 private static final String[] TH_SUFFIX = ",st,nd,rd,th,th,th,th,th,th,th,th,th,th,th,th,th,th,th,th,th,st,nd,rd,th,th,th,th,th,th,th,st".split(","); public static String getDayOfMonthSuffix(int n) { return TH_SUFFIX[n]; }
