Thread: GregorianCalendar

converting GregorianCaledanr value to String is easy by
using SimpleDateFormat class

but how to convert it into int



------------------------------------
String representation

    public static void main(String[] args)throws IOException
 
    {
        int year,
            month,
            day;
 
        GregorianCalendar cal;
        SimpleDateFormat sdf;
 
        System.out.print("Enter Year: ");
        year = Integer.parseInt(br.readLine( ));
 
        System.out.print("Enter Month:");
        month = Integer.parseInt(br.readLine( ));
 
        System.out.print("Enter Day: ");
        day = Integer.parseInt(br.readLine( ));
 
        cal = new GregorianCalendar(year, month-1, day);
        sdf = new SimpleDateFormat("EEEE");
 
        System.out.println("Day Of Week: " + sdf.format(cal.getTime( )));
    }
 
}

the problem is asking to display it as int

heres the code i hope you understand this

//sets the expiration date
public void setExpDate(GregorianCalendar date)
{
   ........<statement> here
}
 
//returns the epiration year
public int getExpYear(  )
{
  ......<statement> here
}
 
//returns the expriration month
public int getExpMonth( )
{
.....<statement>Here
}
 
//returns the expiration day
public int getExpDay( )
{
 .....<statement> here
}

setting the date is easy , displaying the date by String representaion is easy
but how to display it into an INteger value?


the program is asking me to extend a predefined class (LibraryCard class) by adding such methods
for an expiring date of a card

but to display it as int ...

Oh my....

Time is represented as a long usually and here we go.

calendar.getTimeInMillis();

// Json

ahh so i have to use the method of GregorianCalendar class that can return a value of int

oh my.. the book doesnt give a full detail...... hayzz...

Oh, no you can get the time in milliseconds without the GregorianCalendar, but I thought you wanted to know how to get it from the Calendar.

System.currentTimeMillis();

That will get you the time as a long.

// Json
