I have similar problem :

```
// Import statement:
import java.util.ArrayList;
class PrimeDirective {
// Add your methods here:
public boolean isPrime(int number){
return number;
if (number == 2) {
return true;
}else if (number < 2) {
return false;
}
for (int i = 2; i < number; i++)
if (number % i == 0) {
return false;
}
public ArrayList<Integer> onlyPrimes(int[] numbers) {
ArrayList<Integer> primes = new ArrayList<Integer>();
for (int number : numbers) {
if (isPrime(number)) {
primes.add(number);
}
}
return primes;
}
public static void main(String[] args) {
PrimeDirective pd = new PrimeDirective();
int[] numbers = {6, 29, 28, 33, 11, 100, 101, 43, 89};
System.out.println(pd.isPrime(6));
}
}
```
