java，打印出100到500内所有的闰年，每行最多输出不超过四位

public class LeapYearPrinter {
    public static void main(String[] args) {
        int count = 0;
        for (int year = 100; year <= 500; year++) {
            if (isLeapYear(year)) {
                System.out.print(year + " ");
                count++;
                if (count % 4 == 0) {
                    System.out.println();
                }
            }
        }
    }

    private static boolean isLeapYear(int year) {
        return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
    }
}
