Calendar.getDisplayNames介绍

[英]Returns a map of human-readable strings to corresponding values, for the given field, style, and locale. Returns null if no strings are available.

For example, getDisplayNames(MONTH, ALL_STYLES, Locale.US) would contain mappings from "Jan" and "January" to #JANUARY, and so on.
