Numbers and Currencies
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 section, you will
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.
