title: Improvement of reading and writing an Excel file[POI,Java]
body: <p>is there any possibility to improve reading and writing to an excel file using POI library and Java?
  Right now my code looks like this:</p>
  
  <pre><code>//Reading a file
  FileInputStream fin = new FileInputStream(new File(localizationOfExcelFile));
  Workbook workbook = new XSSFWorkbook(fin);
  
  //Writing to a file
  FileOutputStream fout = new FileOutputStream(new File(localizationOfExcelFile));
  workbook.write(fout);
  fout.close();
  </code></pre>
  
  <p>Thanks a lot in advance!</p>
