    Default Why is this code not printing to console

    I was expecting the while loop inside the main method to print to console.
    What is happening here?

     
class ControlFlow {
  public static void main(String[] args) {
 
 
  int number = 4;
  int finishNumber = 20;
 
  while (number <= finishNumber){
   	number++;
   	if(!isEvenNumber(number)){
       	continue;
   	}
   	System.out.println("Even number "+number);
 
  	}
  }
 
  public static boolean isEvenNumber(int num){
    return (num/2 == 0);
    }
}

    Print out the value of num/2 in the isEvenNumber method to see what values are being tested.

    Also try the modulus operator.
    If you don't understand my answer, don't ignore it, ask a question.
