    Default Leap year

    Hello everyone, and again a novice developer with you)))
    Tell me how to push my code into a loop so that it displays all the high years for the last 10 years)
    I know how to solve the problem without class Time, but the teacher asks that the class be used Time.

    import java.time.*;
     
    public class LeapYear {
     
     
        public static void main(String[] args) {
            boolean leapYearCheck = LocalDate.parse("2012-01-01").isLeapYear();
            System.out.println(leapYearCheck);
     
            }
        }

    Sorry, I do not see a class named Time in the java.time package. Are you sure that is the correct package?

    What version of the JDK are you using?

    I do not see a class called Time in that package. Is Time the correct name?
    What package is the Time class in that your teacher wants you to use?

    Ok, what class(es) are you allowed to use?
    What is wrong with the class and method used in the first post? It uses a class from the java.time package.

    It is allowed to use the whole package, but I need to display all high years in the last 10 years, but using the classes of this package, and not just like I did without this package.

    Ok, that sounds like the code needs a loop for the last 10 years
    and a way to select the high years. What is a high year?

    Ok, the posted code can detect a leap year.
    Now there needs to be a loop to cover the last 10 years.

    Can you make a loop that starts with a year that is 10 years old and increments it by one year until its value is the present year?

    What have you tried?
    Do you know how to write a loop? Start with that. Have a year value (eg 2012) that is 10 years old and increment it until its value is this year (2022).
