title: New to coding and struggling to understand this exercise
body: <p>Here is the exercise: Create a class called SortingTest. In it, create a method that accepts an array of int values as a parameter, and prints out the elements sorted (smallest element first) to the terminal.</p>
  
  <p>Part of this questions is also taking about using HashSets which are supposed to be used. How?? </p>
  
  <p>Here is what I have got so far</p>
  
  <pre><code>import java.util.Arrays;
  import java.util.HashSet;
  
  public class SortingTest {
  
    public void sortArrays(int numbers[]) {
      Arrays.sort(numbers);
      System.out.println(numbers);
  
    }
  }
  </code></pre>
  
  <p>I think I am just not understanding the concept of what it is asking me to do.</p>
