MessageFormat provides a
means to produce concatenated messages in natural language-neutral
way. You use this to construct messages displayed for end
users. MessageFormat takes a
set of objects, formats them, then inserts the formatted
strings into the pattern at the appropriate places.
For example:
package inputOutput;
import java.text.MessageFormat;
import java.util.GregorianCalendar;
public class FormatText
{
public static void main(String[] args)
{
String pattern =
"On {2}, a {0} destroyed {1} houses and caused {3} of damage.";
MessageFormat msgFormat = new MessageFormat(pattern);
Object[] msgArgs =
{
"hurricane",
new Integer(99),
new GregorianCalendar(1999, 0, 1).getTime(),
new Double(10E7)
};
System.out.println(msgFormat.format(msgArgs));
}
} |
which outputs:
On 1/1/99
12:00 AM, a hurricane destroyed 99 houses and caused
100,000,000 of damage.
