Question

In my app I used to have a time picker and a date picker. The date and time was stored using SimpleDateFormat.
It looked like this:

public static final String DATE_TIME_FORMAT = "dd-MM-yyyy kk:mm:ss";

new SimpleDateFormat(DATE_TIME_FORMAT);

Now I want to make some changes and instead of having a time and a date picker I would like to have two date pickers. The problem is that I cannot store two dates like that.
Why is this not possible:

public static final String DATE_TIME_FORMAT = "dd-MM-yyyy dd-MM-yyyy";

new SimpleDateFormat(DATE_TIME_FORMAT);

I don’t know what you’re trying to do, but having 2 date pickers on your screen implies 2 objects. Each with their own format (which may, or may not be, the same).

public static final String DATE_TIME_FORMAT = "dd-MM-yyyy";

public static SimpleDateFormat format = new SimpleDateFormat(DATE_TIME_FORMAT);
public static Date date1 = new Date();
public static Date date2 = new Date();

static {
    System.out.println(format.format(date1));
    System.out.println(format.format(date2));
}
