Retrieving month name with the month number

Question

I'm modifying a calendar and there is a case where I'm given a month number and I need to compare it with a month name.

Of course, I could create a switch statement, but I was wondering if I can obtain the month name from the number or vice versa to do the conditional.

Thanks!

Answer 1

If you compare the int number with Calendar 's month constants (ie, JANUARY , AUGUST , etc.), there won't be a problem with having the number instead of the name.

Here's a way to get the actual name, if you need it:

String getMonthForInt(int m) {
    DateFormatSymbols dfs = new DateFormatSymbols();
    String[] months = dfs.getMonths();
    if (m >= 0 && m <= 11 ) {
        return months[m];
    }
    return null;
}

将月份名称存储在List<String> ，并使用list.indexOf(monthName)查找其索引（数字从0开始），并使用list.get(index)获取给定月份数字的名称（仍然从0）。
