title: Handle != null check for two variable
body: <p>I have below code, which i am checking not null check for two variables. </p>
  
  <pre><code> if (userParameter != null || configurationParameter != null){
     add.userParameter();
     add.configurationParameter();
   }
  </code></pre>
  
  <p>Is there any way I can check for not <code>null</code> in one <code>if</code>condition like <code>if((userParameter or configurationParameter) != null)</code> in java.</p>
