用ｊａｖａ找到2到100之间的所有质数

好的，以下是用Java实现的代码：

public class PrimeNumbers {
    public static void main(String[] args) {
        int lowerBound = 2;
        int upperBound = 100;
        System.out.println("Prime numbers between " + lowerBound + " and " + upperBound + " are: ");
        for (int i = lowerBound; i <= upperBound; 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;
    }
}

这个程序会输出2到100之间的所有质数，结果如下所示：

Prime numbers between 2 and 100 are: 
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
