Calendar Class rollback

[hostel]

when we use the calendar class and enter the date in date object as 45/8/2007(dd/mm/yyyy). it will automatically roll forward as 15/9/2007(dd/mm/yyyy)

Logically this should not happen as date cannot be greater than 31 ,

How to avoid roll back and i also need help in validating date

thanks in advance

Then I think it can not be done using Calendar Class.
Then you should have your own Class.
Wait sometimes let the experts say.
Then proceed with your own class.

Have you looked at the API? You would have found the method setLenient in both DateFormat and Calendar:

DateFormat.setLenient
Calendar.setLenient

Your note made it sound like you are not using DateFormat, but you should use it to parse dates. Here is a demo showing the effect of setLenient:

import java.text.*;
import java.util.*;
 
public class DateParsingExample {
    public static void main(String[] args) {
        String data = "45/8/2007";
        DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
        boolean[] lenientSettings = {true, false};
 
        for (boolean lenient : lenientSettings) {
            try {
                df.setLenient(lenient);
                System.out.println("lenient = " + lenient);
                Date date = df.parse(data);
                System.out.println(date);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
    }
}
