how to get value from Set<>
<pre><code> /**
     * @return Returns the parameters.
     */
    public Set&lt;FeatureParameterDTO&gt; getParameters() {
        return this.parameters;
    }
</code></pre>

<p>how can i get value from <code>getParameters</code>? <code>toString</code> is not ok? What is correct way?</p>
