How to return a Set in Java
<p>I have a class, <code>classA</code>, that has a constructor which uses objects from another class, <code>classB</code>. I use these objects of <code>classB</code> to form a set in <code>classA</code>.
Now, I have a method in <code>classA</code> that is setup to return the elements of the set created in the constructor.</p>

<p>This is where my issue is: I can't figure out the correct syntax to return the set elements. </p>

<p>This is my code:</p>

<pre><code>package testing;
import java.util.*;

public class classA {

    public classA(classB x, classB y) {
        Set&lt;classB&gt; setElements = new HashSet&lt;classB&gt;();
        setElements.add(x);
        setElements.add(y);

    public set&lt;classB&gt; getElements() {
        return setElements; //THIS IS WHERE MY ERROR IS. HOW DO I RETURN A SET?
</code></pre>
