Calling a method from different class
<p>Hi so I'm still learning to use methods, but one of my assignments requires me to call a method from a method in a different .java file.</p>

<p>The problem is "Sets" is not recognized and it displays an error message stating that both "Sets" cannot be resolved to a variable. Am I calling the method incorrectly?</p>

<p>This is the method if it is relevant. It comes from a java file called Sets.</p>

<pre><code>public static final int Initial_Pop =
        (int)(EARTH_AT * EARTH_BT * 0.4);
</code></pre>

<p>This is the method I'm trying to call the above method..</p>

<pre><code>public static void plusPeople (int[][] earth, int newPerson) {

    int [][] earthpopulation = new int [Sets.EARTH_AT][Sets.EARTH_BT];
}
</code></pre>

<p>I apologize if I'm unclear or did not provide enough information. If so please tell me!</p>
