这个文件里面包含了java设计模式的一些例子讲解

package com.javapatterns.multilingual.number;

import java.util.Locale;
import java.text.NumberFormat;

public class NumberFormatTester
{
   static public void displayNumber(Double amount, Locale currentLocale)
   {

      NumberFormat formatter;
      String amountOut;

      formatter = NumberFormat.getNumberInstance(currentLocale);
      amountOut = formatter.format(amount);

      System.out.println(amountOut + "   " + currentLocale.toString());
   }

   static public void main(String[] args)
   {
      displayNumber(new Double(1234567.89), new Locale("en", "US"));
      displayNumber(new Double(1234567.89), new Locale("de", "DE"));
      displayNumber(new Double(1234567.89), new Locale("fr", "FR"));
