title: How to write clean code in the "if" statement?
body: <p>What will be more clear and why? (using Apache Commons library)</p>
  
  <p>In code below logic is the same:</p>
  
  <pre><code>if(!ArrayUtils.isEmpty(someArray)) {
    some code here ...
  }
  
  //or this variant
  if(ArrayUtils.isNotEmpty(someArray)) {
    some code here ...
  }
  </code></pre>
  
  <p>Many thanks!</p>
