public class CheckYear
{
  public boolean isLeapYear(int year)
  {
    if(year % 4 == 0)
    {
      return true;
    }
    else
    {
      return false;
    }
  }
  public static void main(String[] args)
  {
    Scanner input = new Scanner(System.in);
    System.out.print("Insert a year: ");
    int insertedYear = input.nextInt();
    CheckYear cy = new CheckYear();
    if(cy.isLeapYear(insertedYear))
    {
      System.out.println(insertedYear +
          " is a leap year");
    }
    else
    {
      System.out.println(insertedYear +
          " is not a leap year");
    }
    input.close();
  }
}
