    Red face Beginning java programmer!!!!!!!!!!!!!!!!!! need help

    Hello everyone,

    My names allan i am a beginning java programmer attending school at my home town in Missouri.
    I was given an assignment in my intro to java class to create a certain program and need help setting up an algorithm to write it. If anyone can help it would be greatly appreciated. Below are the detailed instructions.

    Write a program that reads in an integer between 1 and 12 representing a month, and outputs the number of days in that month. Use a Java switch statement to assign the proper number of days based on the month. Be careful about February. It has 28 days unless it is a leap year so you need to know the year you are to determine the number of days for. The year, therefore will also need to be provided. Determining whether a year is a leap year or not can be done using the following rules. A year is a leap year if it is divisible by 4, unless it is also divisible by 100 in which case it is not a leap year, unless it is also divisible by 400 in which case it is a leap year. Write this leap year logic using nested if-else statements.

    I don't want to be un-helpful but you could provide some code to get us started. I don't like the idea of doing your homework for you

    try to study and use this simple calendar format

    heres a 2 simpe proram

    NOTE: these are different with each other
    public class CalendarFormat2 {
        public static void main(String[] args) {
            GregorianCalendar cal = new GregorianCalendar( );
            System.out.println("YEAR : " + GregorianCalendar.YEAR);
            System.out.println("MONTH : " + GregorianCalendar.MONTH);
            System.out.println("DATE :" + GregorianCalendar.DATE);
            System.out.println("DAY_OF_YEAR: " + cal.DAY_OF_YEAR);
            System.out.println("DAY_OF_MONTH: " + cal.DAY_OF_MONTH);
            System.out.println("DAY_OF_WEEK: " + cal.DAY_OF_WEEK);
            System.out.println("WEEK_OF_YEAR: " + cal.WEEK_OF_YEAR);
            System.out.println("WEEK_OF_MONTH: " + cal.WEEK_OF_MONTH);
            System.out.println("AM_PM: " + cal.AM_PM);
            System.out.println("HOUR: " + cal.HOUR);
            System.out.println("MINUTE: " + cal.MINUTE);

    the second one:

     * @Program: Program that display the exact day of a given date using the
     *           GregorianCalendar class.
     *           The value of the date is accepted as Integer number.
     * @author   
    public class CalendarFormat4 {
        private static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        public static void main(String[] args)throws IOException {
            int year,
            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( )));
