This is in java, I need the answer for the second question, my current code for the first problem is:
import java.util.Scanner;
public class leapYear
{
//-----------------------------------------------------------------
// Determines and prints if a year is a leap year ( and therefore
// has 29 days in February) in the Gregorian calendar.
//-----------------------------------------------------------------
public static void main (String[] args)
{
int year;
Scanner scan = new Scanner (System.in);
System.out.println ("This program will help you to determine ");
System.out.println ("if the year is a leap year. Enter any ");
System.out.println ("year that is greater than 1581. ");
System.out.print ("Enter the year here: ");
year = scan.nextInt();
if (year > 1581)
{
if (year % 4 == 0 && year % 100 != 0 || year % 400 == 0)
System.out.println ("This year is a leap year.");
else
System.out.println ("This year is not a leap year.");
}
else
System.out.println ("Try it again");
}
}
Write a program that reads an integer value from the user rep-
resenting a year. The purpose of the program is to determine if the year is a leap year (and therefore has 29 days in February) in the Gregorian calendar. A year is a leap year if it is divisible by 4 unless it is also divisible by 100 but not 400. For example, the year 2003 is not a leap year, but 2004 is. The year 1900 is not a leap year because it is divisible by 100, but the year 2000 is a leap year because even though it is divisible by
100, it is also divisible by 400. Produce an error message for
any input value less than 1582 (the year the Gregorian calendar
was adopted).
Modify the solution to the previous project so that the user can
evaluate multiple years. Allow the user to terminate the program
using an appropriate sentinel value. Validate each input value to
ensure it is greater than or equal to 1582
