Question

I am writing a class to simplify all the operations that I could make with a GregorianCalendar.
The operations that I need to make are:
-Getting the date in string format, translated to Italian;
-Making the subtraction between two dates.
I havent’ used Calendar,Date and Time classes because they have a lot of deprecated methods.
Also, the tag isn’t gregoriancalendar because I may need to use another class (but feel free to modify it if not agree).
However this is the class:

package TruckingCompany;

import java.util.GregorianCalendar;
import java.util.Locale;

@SuppressWarnings("serial")
public class TCCalendar extends GregorianCalendar
{
public TCCalendar()
{
    super(Locale.ITALY);
}
@Override
public String toString()
{
    String str=new String();
    switch(get(DAY_OF_WEEK))
    {
        case 1: 
            str+="Domenica "; 
            break;
        case 2:
            str+="Lunedì ";
            break;
        case 3:
            str+="Martedì ";
            break;
        case 4:
            str+="Mercoledì ";
            break;
        case 5:
            str+="Giovedì ";
            break;
        case 6:
            str+="Venerdì ";
            break;
        case 7:
            str+="Sabato ";
            break;
    }
    str+=get(DAY_OF_MONTH);
    switch(get(MONTH))
    {
        case 0:
            str+=" Gennaio ";
            break;
        case 1:
            str+=" Febbraio ";
            break;
        case 2:
            str+=" Marzo ";
            break;
        case 3:
            str+=" Aprile ";
            break;
        case 4:
            str+=" Maggio ";
            break;
        case 5:
            str+=" Giungo ";
            break;
        case 6:
            str+=" Luglio ";
            break;
        case 7:
            str+=" Agosto ";
            break;
        case 8:
            str+=" Settembre ";
            break;
        case 9:
            str+=" Ottobre ";
            break;
        case 10:
            str+=" Novembre ";
            break;
        case 11:
            str+=" Dicembre ";
            break;
    }
    str+=get(YEAR)+ " Ore ";
    str+=get(HOUR_OF_DAY)+ ":";
    str+=get(MINUTE)+":";
    str+=get(SECOND);
    return str;
}
}

I use linux and the time is correctly set to 10:19 (Italian hour).
But now (at 10:20 local hour) I get as result of the toString method:
“Venerdì 2 Marzo 2012 Ore 13:21:10”
Don’t look at the Italian stuff, the problem is the hour: get(HOUR_OF_DAY) returns 13 instead of 10 (22:21).
Also, there is another class more intuitive? I have searched in javadoc and except Calendar,GregorianCalendar, Date and Time I haven’t found anything else.

Answer 1

The problem is most likely with the

super(Locale.ITALY)

It will
Constructs a GregorianCalendar based on the current time in the “default time zone” with the given locale.

You will most probably need to change the TIMEZONE too.

I would use this one:

GregorianCalendar(TimeZone zone, Locale aLocale)
