    Default How to read multiple integers without assigning them to seperate variables?

    I have this program that i need to be able to take multiple integers(in this case years) from the user. So far the program works with just one integer. I need the program to be able to take in multiple years seperated by a space in one line of input.
    thanks in advance!
    import java.util.Scanner;
     
    public class GregorianCalendar {
    			public static void main (String[] args) {
    		    	Scanner scan  = new Scanner(System.in);
    			int year;
    			System.out.print("Enter the year: ");
    			year = scan.nextInt();
    			    if (year < 1582){
    			    	System.out.println("Error; year invalid");
    			    	System.exit(0);
    			    }
    			if (year % 4 == 0) {
    				if (year % 100 != 0) {
    				System.out.println(year + " is a leap year");
    			    }
    			    else if (year % 400 == 0) {
    				System.out.println(year + " is a leap year");
    			    }
    			    else {
    				System.out.println(year + " is not a leap year");
    			    }
    			}
    			else {
    			    System.out.println(year + " is not a leap year");
    			}
    			}
        }

    Read the entire line of input as a String. Then use a String method to break that single String into an array containing the years as individual Strings.
