title: Issue while reading Excel document (Java code)
body: <p>I have some Java code which reads the Excel data. On running the Java code, it's showing the following error. Help me resolve the same. Also, I need to know other method of reading <em>.xlsx</em> file.</p>
  
  <p>(A small edit) how I can print rows with their respective columns. For example: </p>
  
  <pre><code>Age
  19
  20
  21
  
  Salary
  35k
  20k
  40k
