How to print the value of this boolean? (Java)

I tried several different methods such as print (boolean isLeapYear) and several others, but I cannot figure out how to make it work. It is always said that I have missed a class (a boolean primitive, is it needed?) In any case, if the isLeapYear if-else statements are incorrect, I'm not worried about this ... I just need to figure out how to print from the boolean value; any help / point in the right direction is much appreciated =]

import java.util.Scanner;

public class booleanfun    {
    boolean isLeapYear;

    public static void main(String[] args)
    {
        System.out.println("Enter a year to determine if it is a leap year or not: ");
        Scanner kboard = new Scanner(System.in);
        int year = kboard.nextInt();
    }
public boolean isLeapYear(int year)
  {
    if (year % 4 != 0)
        isLeapYear = false;

    else if ((year % 4 == 0) && (year % 100 == 0))
        isLeapYear = false;

    else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0))
        isLeapYear = true;

    else
        isLeapYear = false;

System.out.println(isLeapYear);
System.out.println(boolean isLeapYear);

    return isLeapYear;
    }
}

System.out.println(isLeapYear);

should work fine.

By the way, in

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = false;

else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0))
    isLeapYear = true;

the part year % 400will never be achieved, because if (year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0)true, then it (year % 4 == 0) && (year % 100 == 0)must be fulfilled.

Perhaps replace these two conditions or reorganize them:

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = (year % 400 == 0);
