Answer 4

Several ways you could do it so it depends on how much you already know about java. Given the level of the question I will assume it is a console app and not a gui. See if this is helpful in getting started.

Your main function could be something like:

// Create an instance of the input stream
Sacnner in = new Scanner(System.in);
int month, year; // Create two integer variables

// Ask the user for input
System.out.println("Please enter a number between 1 and 12");
month = in.nextInt(); // record the input into the variable
System.out.println("Please enter a year");
year = in.nextInt();

/* Do some error checking to be certain of legit values */

/* Put in some evaluations to determine the number entered */
days = /* some calc */
/* Print the results */
System.out.println("The number of days in the "+ month + " is " + days +".");
