Get Help Java
#1 
I am getting this below error but I am not understanding what I have done wrong could you please help me with this?
Below is my Program:

// Import statement:
import java.util.ArrayList;
class PrimeDirective {
  
  // Add your methods here:
  public boolean isPrime(int 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;
    } else {
    return true;
}
return false;
  }
  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(7));

  }  

}

The for statement looks like it isn’t inside the method. Check the brackets.

After the if inside the for no else is necesary en outside the for yo only need to return true

public boolean isPrime(int 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;
    }
    return true;
  }
