          public abstract NumberFormat getCurrencyInstance(Locale locale)

      Returns a new `NumberFormat` instance which formats monetary values for the specified locale.
      Parameters:
        `locale` - the desired locale.
      Returns:
        a currency formatter
      Throws:
        `NullPointerException` - if `locale` is null

    - #### getIntegerInstance

          public abstract NumberFormat getIntegerInstance(Locale locale)

      Returns a new `NumberFormat` instance which formats integer values for the specified locale. The returned number format is configured to round floating point numbers to the nearest integer using half-even rounding (see `HALF_EVEN`) for formatting, and to parse only the integer part of an input string (see `isParseIntegerOnly`).
      Parameters:
        `locale` - the desired locale
      Returns:
        a number format for integer values
      Throws:

      Parameters:
        `locale` - the desired locale
      Returns:
        a general-purpose number formatter
      Throws:
        `NullPointerException` - if `locale` is null
