Type of a wildcard object without using "instanceof"
<p>In the code below, I don't want to use <code>instanceof</code> to know the type of repository.
Is it the only way to get the type? Is it possible to know de type with the wildcard <code>RepositoryVet&lt;?&gt;</code>? This would save me doing lots of test.</p>

<pre><code>public ArrayList&lt;String&gt; rechercherTabTailles(String sexe,String SI,RepositoryVet&lt;?&gt; repository) {
    ArrayList&lt;String&gt; tabTailles;
    repository.Open();
    repository.rechercherspin(sexe);
    if (SI.compareTo("US") ==  0) {
        if (repository instanceof ChaussureRepository) 
            tabTailles= ((ChaussureRepository) repository).taillesUS;
        if (repository instanceof ChemiseRepository) 
            tabTailles= ((ChemiseRepository) repository).taillesUS;
    }
}
</code></pre>

<p>To complete my question :
RepositoryVet is already an abstractClass defined like this :</p>

<p>public abstract class RepositoryVet implements IRepositoryVet {</p>

<pre><code>public ArrayList&lt;String&gt; taillesEU;
public ArrayList&lt;String&gt; taillesUS;
public ArrayList&lt;String&gt; taillesUK;
public ArrayList&lt;String&gt; taillesIT;
public ArrayList&lt;String&gt; taillesJP;
public ArrayList&lt;String&gt; taillescm;
public ArrayList&lt;String&gt; taillesinch;
</code></pre>

<p>etc....
}</p>

<p>And "ChaussureRepository" is a class that extends RepositoryVet like this :</p>

<p>public class ChaussureRepository extends RepositoryVet {</p>

<pre><code>public ArrayList&lt;String&gt; taillesEU;
public ArrayList&lt;String&gt; taillesUS;
public ArrayList&lt;String&gt; taillesUK;
public ArrayList&lt;String&gt; taillesIT;
public ArrayList&lt;String&gt; taillesJP;
public ArrayList&lt;String&gt; taillescm;
public ArrayList&lt;String&gt; taillesinch;
</code></pre>

<p>etc....</p>
