How to check if a given year is a leap year in Java?

In Java, you can check if a given year is a leap year using the following code:

This code uses the standard rule that a year is a leap year if it is divisible by 4, except for years that are divisible by 100 but not divisible by 400.

To use this method, you can simply call it with the year you want to check as the argument, like this:

public static boolean isLeapYear(int year) {
    if (year % 4 == 0) {
        if (year % 100 == 0) {
            if (year % 400 == 0) {
                return true;
            }
            else {
                return false;
            }
        }
        else {
            return true;
        }
    }
    else {
        return false;
    }
}

int year = 2024;
if (isLeapYear(year)) {
    System.out.println(year + " is a leap year");
}
else {
    System.out.println(year + " is not a leap year");
}
