在Java中，我试图找到一个介于10到99之间的质数，但我收到的信息是，该范围内的所有数字都不是质数

public class PrimeNumber {
    public static void main(String[] args) {
        int start = 10;
        int end = 99;

        System.out.println("Prime numbers between " + start + " and " + end + " are: ");
        for (int i = start; i <= end; i++) {
            if (isPrime(i)) {
                System.out.print(i + " ");
            }
        }
    }

    public static boolean isPrime(int number) {
        if (number <= 1) {
            return false;
        }

        for (int i = 2; i <= Math.sqrt(number); i++) {
            if (number % i == 0) {
                return false;
            }
        }

        return true;
    }
}
