    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.
