title: What's the difference between calling through and object vs class
body: <p>What's the difference between calling a method through an object vs a class.</p>
  
  <p>for example the Class Bob</p>
  
  <pre><code>public class SecretNumber() {
      public static int secretNumber = 2;
      public static void changeSecretNumber(){
          secretNumber++;
      }
  }
  </code></pre>
  
  <p>What would be the difference if i called it like an object</p>
  
  <pre><code>SecretNumber secretNumber = new SecretNumber();
  secretNumber.changeSecretNumber();
  </code></pre>
  
  <p>vs calling it like this</p>
  
  <pre><code>SecretNumber.changeSecretNumber();
  </code></pre>
  
  <p>How would one method effect the other?</p>
