    text
    copied!<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>
