public class Test {      private static final char[] data = new char[] { '零', '壹', '贰', '叁', '肆',       '伍', '陆', '柒', '捌', '玖' };    private static final char[] units = new char[] { '元', '拾', '佰', '仟', '万',       '拾', '佰', '仟', '亿' };    public static String convert(int money) {     StringBuffer sbf = new StringBuffer();     int unit = 0;     while (money != 0) {       sbf.insert(0, units[unit++]);       int number = money % 10;       sbf.insert(0, data[number]);       money /= 10;     }     return sbf.toString();   }       public static void main(String[] args) {     // TODO Auto-generated method stub     System.out.println(convert(135689123));   } }
