Number and Currency Formatting
Programs store and operate on numbers
in a locale-independent way.
Before displaying or printing a number,
a program must convert it to a String
that is in a locale-sensitive format.
For example, in France the number
123456.78 should be formatted as 123 456,78,
and in Germany it should appear as 123.456,78.
In this lesson, you'll learn how to make
your programs independent of the locale
conventions for decimal points, thousands-separators,
and other formatting properties.
Using the
the factory methods provided by the
NumberFormat class,
you can get locale-specific
formats for numbers, currencies, and percentages.
With the DecimalFormat
class you specify a number's format
with a String pattern.
The DecimalFormatSymbols class
allows you to modify formatting symbols
such as decimal separators and minus signs.
