Java date 日期转换24小时制 失败,该如何解决

Java date 日期转换24小时制 失败
SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss", Locale.CHINA);
  String dateString = "18:50:36";
  Date timeDate = null;
dateFormat.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));
dateFormat.setLenient(true);
try
{
timeDate = dateFormat.parse(dateString);
} catch (ParseException e)
{
timeDate = new Date();/* set to current time if anything is wrong */
Log.e(Log_tag, "The date format string is failed to parse! time_ = " + time_);
}

首先这个问题我已经在google上找了很久了，还是解决不掉，所以想请教大侠们：
转换后的时间怎么会变成 6:50:36, 怎么不是24小时制的Date，

[解决办法]
你的输出为6:50:36肯定你代码哪个地方的原因，单纯你给的这些代码不可能出现这种情况
给你贴一个例子

Java code

import java.util.TimeZone;import java.util.Date;import java.util.Locale;import java.text.SimpleDateFormat;import java.text.ParseException;/** * Created by IntelliJ IDEA. * User: Administrator * Date: 2011-9-29 * Time: 21:12:06 * To change this template use File | Settings | File Templates. */public class CalendarTest1 {    public static void main(String[] args){        SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss", Locale.CHINA);                String dateString = "18:50:36";        Date timeDate = null;        dateFormat.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));        dateFormat.setLenient(true);        try{            timeDate = dateFormat.parse(dateString);            System.out.println(dateFormat.format(timeDate));//输出24小时制的时间            dateFormat.applyPattern("aa hh:mm:ss"); //输出12小时制 的时间                        System.out.println(dateFormat.format(timeDate));        } catch (ParseException e)        {            timeDate = new Date();/* set to current time if anything is wrong *///            Log.e(Log_tag, "The date format string is failed to parse! time_ = " + time_);        }    }}
[解决办法]
int hour = cal.get(Calendar.HOUR); //这个是12小时制
改成
int horu = cal.get(Calendar.HOUR_OF_DAY); //这个是24小时制
