title: Check if StringBuffer is empty
body: <p>Can anyone please tell me how I can use if-else condition with StringBuffer to check if it is empty? </p>
  
  <p>I am expecting something like this</p>
  
  <pre><code>if (Stringbuffer is empty){ 
      // some condition 
  }
  else {
     // some other condition
  }
  </code></pre>
