Formatting |
Programs store and operate on numbers in a locale-independent way. Before displaying or printing a number, a program must convert it to aString
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 Predefined Formats
Using the the factory methods provided by theNumberFormat
class, you can get locale-specific formats for numbers, currencies, and percentages.Formatting with Patterns
With theDecimalFormat
class you specify a number's format with aString
pattern. TheDecimalFormatSymbols
class allows you to modify formatting symbols such as decimal separators and minus signs.
