If the starting year is greater than the ending year or one of the inputs is negative, an appropriate error message should be printed. .java = LeapYears.java Examples (a) printLeapYears(2000, 2010) prints out: 2000 2004 2008 (b) printLeapYears(2000, 2000) prints out: 2000 (c) printLeapYears(

Answer 1

public class LeapYears {
    public static boolean isLeap(int year){
        if(year % 4 == 0 && year % 100 != 0){
            return true;
        }
        else if(year % 400 == 0){
            return true;
        }
        return false;
    }

    public static void printLeapYears(int year1, int year2){
        for(int i = year1;i<=year2;i++){
            if(isLeap(i)){
                System.out.print(i+" ");
            }
        }
        System.out.println();
    }

    public static void main(String[] args) {
        // Testing
        printLeapYears(2000, 2010);
        printLeapYears(2000, 2000);
    }
