Question

我正在尝试将日期字符串解析为日期。我试过以下代码

public class convertDate
{
    public static void main(String args[])
    {
        String strlastruntime ="16/06/2016 9:17:00 AM",dateFormat ="MM/dd/yyyy hh:mm:ss a";

        try
        {
            strlastruntime = strlastruntime.trim();
            System.out.println("strlastruntime = "+strlastruntime+" dateFormat = "+dateFormat);
            java.util.Locale l = java.util.Locale.US;
            java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat(dateFormat,l);
            //System.out.println("formatter = "+formatter);
            java.util.Date date = formatter.parse( strlastruntime );
            System.out.println("date = "+date);
            long time = date.getTime();
            System.out.println("time = "+time);

        }
        catch(java.text.ParseException ee)
        {
            ee.printStackTrace();
            System.out.println(ee);
        }
    }
}

但是，上面的输入字符串输出错误我在运行代码时得到了这个输出：

strlastruntime = 16/06/2016 9:17:00 AM dateFormat = MM/dd/yyyy hh:mm:ss a
date = Thu Apr 06 09:17:00 IST 2017
time = 1491450420000

所以，请帮我找到解决方案..

更改dateFormat ="MM/dd/yyyy hh:mm:ss a"; 到dateFormat ="dd/MM/yyyy hh:mm:ss a";

完整代码

public static void main(String args[])
    {
        String strlastruntime ="16/06/2016 9:17:00 AM",dateFormat ="dd/MM/yyyy hh:mm:ss a";

        try
        {
            strlastruntime = strlastruntime.trim();
            System.out.println("strlastruntime = "+strlastruntime+" dateFormat = "+dateFormat);
            java.util.Locale l = java.util.Locale.US;
            java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat(dateFormat,l);
            //System.out.println("formatter = "+formatter);
            java.util.Date date = formatter.parse( strlastruntime );
            System.out.println("date = "+date);
            long time = date.getTime();
            System.out.println("time = "+time);

        }
        catch(java.text.ParseException ee)
        {
            ee.printStackTrace();
            System.out.println(ee);
        }
    }

输出：

strlastruntime = 16/06/2016 9:17:00 AM dateFormat = dd/MM/yyyy hh:mm:ss a
date = Thu Jun 16 09:17:00 IST 2016
time = 1466048820000
