Can somebody explain 2.24 to me? Also, why not including 1 as an output because count 2 <= 2 (new number)

Question

public static void oddStuff() {
int number = 4
for (int count = 1; count <= number; count++) {
System.out.println(number);
number = number / 2;
}
}

output: 4

        2

Answer 1

I would recommend running this code through the Online Java Visualizer, to see how it runs step-by-step, and what the value of the variables are at each step. However, to run it, you'll need to change it into a full Java class with a main method, like this:

public class OddStuffTest {
  public static void main(String[] args) {
    oddStuff();
  }
  public static void oddStuff() {
    int number = 4;
    for (int count = 1; count <= number; count++) {
      System.out.println(number);
      number = number / 2;
    }
  }
}

If watching it execute step-by-step doesn't help, I believe our dedicated tutor Maegan will still be in the Olin 204 lab tonight from 7-9 PM tonight (despite the blizzard!), and she could certainly help you out!

Hopefully one of your classmates will also post a more detailed answer than this!

Thank you! I got it!

I agree with this
