Servlet get date and time

Question

I'm using the following code to get the date and time

public class offer extends HttpServlet {


@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

    response.setContentType("text/html;charset=UTF-8");
    PrintWriter out = response.getWriter();
    try {

        out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet offer</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h1> sv sugar mills</h1>");
        doPost(request,response);
        out.println("</body>");
        out.println("</html>");

    } finally {
        out.close();
    }
} 

 @Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
     response.setContentType("text/html;charset=UTF-8");
     PrintWriter out = response.getWriter();
     java.sql.Date sqlDate=null,ofrmonth=null,ctime=null;

    dat="14/02/2013";
    try
    {
     java.util.Date date=new SimpleDateFormat("dd/MM/yyyy").parse(dat);
     //ctime=new java.sql.Date(date.getTime());
     sqlDate = new java.sql.Date(date.getTime());
     out.println(sqlDate);
     out.Println(ctime);
    }
    catch(Exception e)
    {
     out.println(e);
    }
 }
@Override
public String getServletInfo() {
    return "Short description";
}// </editor-fold>

}

Here, the util.Date variable date is displayed as "Thu Feb 14 00:00:00 IST 2013". So I get the sql.Date easily as "2013-02-14". Also, I want to get the time from it. In the ctime variable I want to get the time and display it. The format should be 24hours format. But I don't know how to get it.

I've used some functions like getHours() and getDate(), but I couldn't found the solution. Can someone help me to get the time. Thanks in advance

I need the time as 00:00:00 (hh:mm:ss)

Please post compilable code that actually demonstrates what problem you're having. As-is your question makes little sense; you don't *have* a time, only a date. Furthermore `java.sql.Date` is *only* the date - it represents a SQL DATE — Brian Roach, Feb 14 '13 at 05:53
Please consult the documentation for [java.util.Date](http://docs.oracle.com/javase/6/docs/api/java/util/Date.html), [java.sql.Date](http://docs.oracle.com/javase/6/docs/api/java/sql/Date.html), and [Calendar](http://docs.oracle.com/javase/6/docs/api/java/util/Calendar.html). There is a ton of information in these links. You should also google around for some simple examples. Unless you have a specific need, you should use `java.util.Date` rather than `java.sql.Date`, which you are currently using. — jahroy, Feb 14 '13 at 06:57
What `doPost` is being used for here is nonsensical. Instead of using `doPost` for this you should make another function called something like `printDate()` and call that in your `doGet`. `doPost` should never call `doGet` nor should `doGet` call `doPost` unless that is all they are doing, namely to make both do the exact same thing. And even that, most developers would frown on. But at least that makes sense. — developerwjk, Dec 15 '14 at 22:55

Try this:

Calendar c = Calendar.getInstance();
c.setTime(sqlDate);
System.out.println(c.get(Calendar.HOUR));
System.out.println(c.get(Calendar.MINUTE));
System.out.println(c.get(Calendar.SECOND));

Unless you set a time zone for the Calendar object the above returns time in your machine's time zone.

And if you want a single String in the form of HH:mm:ss as output, you can use a SimpleDateFormat as pointed out by @zvzdhk.

Snippet:

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("IST"));
System.out.println(sdf.format(sqlDate));

Note that TimeZone.getTimeZone allows argument like "GMT+5:30", "PST" etc. Read the documentation for more.
