Problems with Calendar exercise

[Jude]

I have been set a task to display a calendar for any given month and year.
I made a start by using a text book but I cant seem to get what i need from it.

So far I have used GregorianCalendar and I can display a calendar. I first thought it was todays date but it isn't it seems to be a random month and year.
Although I am having alot of problems the biggest problem is that I need to be able to input a given month and year, and then display that.
I have read that I can use scanner or get (I think?) :confused:

I need alot of help and explaining for this as I am absolutly new to java. Any help or advice would be appreciated. Thanks. :)

import java.text.*;
import java.util.*;

public class Test {
    public static void main(String[] args) {
        // Calendar practice.
        DateFormat df = new SimpleDateFormat("dd MMM yyyy");
        Date now = Calendar.getInstance().getTime();
        System.out.println("now = " + now);
        System.out.println("now = " + df.format(now));
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.MONTH, Calendar.MAY);
        System.out.println("set to May = " + df.format(calendar.getTime()));
        calendar.set(1997, 8, 24);
        System.out.println("set to 1997 = " + df.format(calendar.getTime()));
        calendar.roll(Calendar.DAY_OF_MONTH, 7);
        System.out.println("7 days ahead = " + df.format(calendar.getTime()));
        // Try some input.
        Scanner scanner = new Scanner(System.in);
        System.out.println("enter a four digit year");
        int year = scanner.nextInt();
        System.out.println("enter a Month");
        int month = scanner.nextInt();
        System.out.println("Enter a day of the month");
        int day = scanner.nextInt();
        System.out.printf("year = %d  month = %d  day = %d%n",
                           year, month, day);
        scanner.close();
        calendar.set(year, month, day);
        System.out.println("you entered " + df.format(calendar.getTime()));
    }
