My code in adding condition of range 1 - 9999 is not working using switch statement

So I created LeapYearCal this on If else statement I learn switch statement I want to recreate it using switch. Somehow my condition for leap is working, but I want to add condition like value must be in 1- 9999 only else it'll returned false. but when my code is incorrect How do I solve the problem?

public static boolean isLeapYear(int year)
{
    switch ( year % 4)
    {
        case 0:
            if (year % 100 == 0)
            {
                    if ( (year % 400 == 0) )
                    {
                       if (year > 0)
                       {
                            if (year <= 9999)
                            {
                                return true;
                            }
                             else
                                return false;
                       }
                       else
                           return false;
                    }
                    else
                        return false;
            }
            else
                return true;
        default:
             break;
    }
    return false;

I want to the output "True" if the year is Leap year and it's range 1-9999 else "False" if it is not in range regardless if its leap year
