title: boolean[] cannot be resolved to a variable
body: <p>In the class <code>SitoEratostenesaTest</code>, I have:</p>
  
  <pre><code>SitoEratostenesa myObj = new SitoEratostenesa(liczby[x]);
  
  for(i=1; i&lt;ilosc; i++)
  {
      if(tab[i])
      {
          System.out.println((i+1)+" jest liczba pierwsza");
      }
      else
      {
          System.out.println((i+1)+" jest liczba zlozona");
      }
  }
  </code></pre>
  
  <p><code>boolean tab[]</code> was created in class <code>SitoEratostenesa</code>. How can I use this table in my condition?</p>
