给数字加上单位万

    public String getNum(String value) {        try {            double v = Double.parseDouble(value);            if (v > 10000) {                String str = String.valueOf(v / 10000);                return removeLast0(str) + "万";            } else {                return value;            }        } catch (Exception e) {            return value;        }    }

去掉后面的0

    private  String removeLast0(String string) {        if (string==null || string.length() == 0) {            return "0";}        try {            while (string.charAt(string.length() - 1) == '0') {                string = string.substring(0, string.length() - 1);            }            if (string.charAt(string.length() - 1) == '.') {                string = string.substring(0, string.length() - 1);            }        } catch (Exception e) {            return "";        }        return string;    }
