title: Calling Static Void Methods
body: <p>I'm still learning to use methods, but I hit another stump in the road. I'm trying to call a static void method in another static void method. So it roughly looks like this:</p>
  
  <pre><code>public static void main(String[] args) {
  ....
  }
  
  //Method for total amount of people on earth
  //Must call plusPeople in order to add to total amount of people
   public static void thePeople (int[][] earth) {
  How to call plusPeople?
  }
  
  //Method adds people to earth
  //newPerson parameter value predefined in another class.
  public static void plusPeople (int[][] earth, int newPerson) {
  earth = [newPerson][newPerson]
  }
  </code></pre>
  
  <p>I've tried a few different things which hasn't really worked.</p>
  
  <pre><code>int n = plusPeople(earth, newPerson); 
  //Though I learned newPerson isn't recognized 
  because it is in a different method.
  
  int n = plusPeople(earth); \
  //I don't really understand what the error is saying,
  but I'm guessing it has to do with the comparison of these things..[]
  
  int n = plusPeople;
  //It doesn't recognize plusPeople as a method at all.
  </code></pre>
  
  <p>I feel very stupid for not being able to even call a method, but I've literally been stuck on this issue for about two hours now.</p>
