java.text.MessageFormat格式化字符串时的小技巧

    public static void main(String[] args) throws InterruptedException {
        MessageFormat form = new MessageFormat(
                "{2,date,yyyy-MM-dd HH:mm:ss.SSS} The disk \"{1}\" contains {0,number,#.##} file(s).{3}");
        int fileCount = 1273273237;
        String diskName = "MyDisk";
        Object[] testArgs = {new Long(fileCount), diskName, new Date(),new Date()};
        System.out.println(form.format(testArgs));
    }

执行结果：

2016-05-26 13:41:59.162 The disk "MyDisk" contains 1273273237 file(s).16-5-26 下午1:41
