Textual Equivalent

[John E]

What is the best way to store a string equivalent of an integer in Java?

"January" = 1
"February" = 2

etc...

TIA

Using a Hashtable? For example:

Hashtable hash = new Hashtable();
hash.put("January", new Integer(1));
hash.put("February", new Integer(2));

However if you genuinely are just working with months then you might be
coming at this from the wrong angle. Typically you'd use integers to
represent the months and then have an array of month-names.

What if I had to randomly generate two possible textual values? e.g. "Heads"
and "Tails"?

"January" = 1
Can't you do something like

// create a GregorianCalendar with the Pacific Daylight time zone
// and the current date and time
Calendar calendar = new GregorianCalendar(pdt);
Date trialTime = new Date();
calendar.setTime(trialTime);

// print out a bunch of interesting things
System.out.println("ERA: " + calendar.get(Calendar.ERA));
System.out.println("YEAR: " + calendar.get(Calendar.YEAR));
System.out.println("MONTH: " + calendar.get(Calendar.MONTH));

This was taken from

Good luck.

I'm not sure how that relates to the January/February problem but use a
randomizer to generate 0 or 1 randomly and then print "Heads" or "Tails".
No doubt the web has better examples but here's one that's more complex than
you need: http://examples.oreilly.com/jenut/Randomizer.java.

"January" = 1
"February" = 2

String[] months = { "January", "February", ... };
