why java program is outputting the following

Below is the code for implementing time server

Server class

public static void main(String args[])
    {
   try{
            ServerSocket ss=new ServerSocket(990);
             Socket s=ss.accept();
            while(true)
            {
                Calendar c=Calendar.getInstance();
                BufferedReader in=new BufferedReader(new InputStreamReader(s.getInputStream()));
                PrintWriter out =new PrintWriter(new OutputStreamWriter(s.getOutputStream()));
                out.println("Hello This is server & My Time is :");
                out.println("Time :::  Hour="+c.HOUR +" Min="+c.MINUTE +" sec="+c.SECOND);
            out.flush();
              s.close();
            }
        }
        catch(Exception e)
        {
        }
    }

Client class

public static void main(String args[])
    {
   try{
            ServerSocket ss=new ServerSocket(990);
             Socket s=ss.accept();
            while(true)
            {
                Calendar c=Calendar.getInstance();
                BufferedReader in=new BufferedReader(new InputStreamReader(s.getInputStream()));
                PrintWriter out =new PrintWriter(new OutputStreamWriter(s.getOutputStream()));
                out.println("Hello This is server & My Time is :");
                out.println("Time :::  Hour="+c.HOUR +" Min="+c.MINUTE +" sec="+c.SECOND);
            out.flush();
              s.close();
            }
        }
        catch(Exception e)
        {
        }
    }

the program is working but the output is always 

time:: hour=10 min=12 sec=13

why it is outputting the above values

That's because you're printing the values of the static integer fields called HOUR, MINUTE, SECOND present in the Calendar class. You need to use the Calendar#get(field) method to get the HOUR, MINUTE, SECOND values from the Calendar.

out.println("Time :::  Hour="+c.get(Calendar.HOUR) +" Min="+c.get(Calendar.MINUTE)+" sec="+c.get(Calendar.SECOND));

Note that since HOUR, MINUTE, SECOND are static fields, you need to access them using the class name(Calendar.SECOND) and not using the instance(c.SECOND).
