Chapter Summary
1. Java is the first language designed from the ground up to support
internationalization. In consequence, it allows your programs to be
customized for any number of countries or languages without requiring
cumbersome changes in the code.
2. Java characters use Unicode in the program. The use of Unicode encoding
makes it easy to write Java programs that can manipulate strings in any
international language.
3. Java provides the Locale class to encapsulate information about a
specific locale. A Locale object determines how locale-sensitive
information, such as date, time, and number, is displayed, and how
locale-sensitive operations, such as sorting strings, are performed. The
classes for formatting date, time, and numbers, and for sorting strings
are grouped in the java.text package.
4. Different locales have different conventions for displaying date and
time. The java.text.DateFormat class and its subclasses can be used to
format date and time in a locale-sensitive way for display to the user.
5. To format a number for the default or a specified locale, use one of the
factory class methods in the NumberFormat class to get a formatter. Use
getInstance or getNumberInstance to get the normal number format. Use
getCurrencyInstance to get the currency number format. Use
getPercentInstance to get a format for displaying percentages.
6. Java uses the ResourceBundle class to separate locale-specific
information, such as status messages and GUI component labels, from the
program. The information is stored outside the source code and can be
accessed and loaded dynamically at runtime from a ResourceBundle, rather
than hard-coded into the program.
7. You can specify an encoding for a text file when constructing a
PrintWriter or a Scanner.
