title: how to check for an empty array java
body: <p>I wanted to know if this code is valid for checking whether an array is empty, or should I check for null?</p>
  
  <pre><code>if(arrayName={})
    System.out.println("array empty");
  else System.out.println("array not empty");
  </code></pre>
  
  <p>Thank you!</p>
