抛出的异常是否表明数组大于索引？如果没有,这是什么意思,为什么？我该如何纠正？

线程"main"中的异常java.lang.ArrayIndexOutOfBoundsException:0在leapyear.LeapYear.main(LeapYear.java:13)

public class LeapYear {

public static void main(String[] args) { 
    int year = Integer.parseInt(args[0]);
    boolean isLeapYear;

    // divisible by 4
    isLeapYear = (year % 4 == 0);

    // divisible by 4 and not 100
    isLeapYear = isLeapYear && (year % 100 != 0);

    // divisible by 4 and not 100 unless divisible by 400
    isLeapYear = isLeapYear || (year % 400 == 0);

    System.out.println(isLeapYear);
}
}
