title: Generic methods don't work with 'int' type variable?
body: <p>I'm having some trouble with the two variables: int and Integer.
  They're roughly the same, but (as shown in the code below) they don't always act the same.
  Here's my problem:
  This piece of code works just perfect. I've made a generic method, printArray which needs an array of any kind of variable (since it is generic) in order to work. 
  Here I use the variable type Integer.
  But, when I change my type of array 'getal' to int (instead of Integer), the method printArray doesn't work annymore. Why is that? Do generic methods not work with int type variables?</p>
  
  <pre><code>package Oefenen;
  
  public class printArray
  {
      public static void main (String args[])
      {
          Integer[] getal = {10, 20, 30, 40, 50};
          printArray(getal);  
      }
  
      public static &lt;E&gt; void printArray (E[] intArray)
      {
          for (E element : intArray)
          {   
              System.out.printf("%s\n", element);
          }
      }
  }
  </code></pre>
  
  <p>ps: If I change the generic method to a method only for int's, it does work. 
  So I was thinking the problem is : Generic methods do not work with int's.
