Array and methods?
<p>I'm doing a task for a course in Java programming and I'm not sure how the following thing is working? The method below takes the value from an array and a integer. The integer should be added to the array and then be used outside the method in other methods and so on, but how could this work when the method has no return for the new content of the array? There is a void in the method? Have I missed something? Preciate some help? Is there something about pointers?</p>

<pre><code>public static void makeTransaction(int[] trans, int amount);
</code></pre>
