Java leap year

In Java, you can check if a year is a leap year or not using a simple condition. A leap year is a year that is divisible by 4, except for years that are both divisible by 100 and not divisible by 400. Here’s a Java program to determine if a given year is a leap year or not:

public class LeapYearChecker {

    public static void main(String[] args) {
        int year = 2023; // Replace this with the year you want to check

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

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

In this code, the isLeapYear method takes an integer year as input and returns a boolean value indicating whether it is a leap year or not. The main method tests the isLeapYear method for a sample year (in this case, 2023), and you can replace it with any other year you want to check.

Remember to replace the year variable with the desired year you want to check before running the code. When you execute the program, it will output whether the year is a leap year or not.
