Formatting date 2/24 as "February, 24"

I am trying t make a date that comes in like this mm/dd turn into the name of the month and day like it comes in 8/15 i want it to say August, 15

public void printAlphabetical()
{
           int month,day;/开发者_如何学JAVA/ i got the month and day from a user previously in my program

       String s = String.format("%B, %02d%n",month,day);
       Date date = new Date();
       date.parse(s);// this does not work
       System.out.printf(s);
}

    System.out.println( new SimpleDateFormat("MMMM, dd").format( 
                          new SimpleDateFormat("MM/dd").parse("2/24") ) );

See Calendar and SimpleDateFormat

You can do something like this,

            DateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
            Date date = (Date)formatter.parse(dateStr + "/2000); // Must use leap year
            formatter = new SimpleDateFormat("MMMM, dd");
            System.out.println(formatter.format(date));

Take a look at the Java simple date format:

https://docs.oracle.com/javase/1.5.0/docs/api/java/text/SimpleDateFormat.html

---

String[] months = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", 
                    "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"}

System.out.println(months[month - 1] + ", " + day);

2/24 as “February, 24”

So, the starting date has a pattern of M/d and the final date has a pattern of MMMM, d?

Use java.text.SimpleDateFormat wisely. First parse the String based on the desired pattern into a Date and then format the obtained Date into another String with the desired pattern.

Basic example:

String datestring1 = "2/24"; // or = month + "/" + day;
Date date = new SimpleDateFormat("M/d").parse(datestring1);
String datestring2 = new SimpleDateFormat("MMMM, d").format(date);
System.out.println(datestring2); // February, 24 (Month name is locale dependent!)
