How can I print total

Question

so I am trying to print the prime numbers between 1 and 100, and the total prime numbers in that range. I know the total prime numbers between 1 and 100 is 25, but I can't think of how to print it out in Java. It keeps printing 71???

Thank you for your help.

public class Chap6_Homework2 {
    public static void main (String [] args) {
        int i;
        int maxprime = 100;
        boolean isPrime = true;
        String foundprimenumbers = "";

        for (i = 2; i <= maxprime; i++) {
            isPrime = PrimeNumbers(i);
            if (isPrime) {
                foundprimenumbers = foundprimenumbers + i + " ";
            }
        }   
    System.out.println("Prime numbers are " + foundprimenumbers);   
    System.out.println("There are " + foundprimenumbers.length() + " prime numbers found.");
    }

    public static boolean PrimeNumbers(int foundprime) {
        for (int i = 2; i <= foundprime / 2; i++) {
            if (foundprime % i == 0) {
                return false;
            } 
        }
        return true;

    }

Change to

int foundprimenumbers = 0;

for (i = 2; i <= maxprime; i++) {
      if (PrimeNumbers(i)) {
        System.out.println(i);
        foundprimenumbers++;
      }
}   
// System.out.println("Prime numbers are " + foundprimenumbers);   
System.out.println("There are " + foundprimenumbers + " prime numbers found.");

where you print the prime number immediately and the count of primnumbers is stored in an int variable
