  import org.apache.poi.xssf.usermodel.*;
  public class CreateWorkBook 
  {
     public static void main(String[] args)throws Exception 
     {
        //Create Blank workbook
        XSSFWorkbook workbook = new XSSFWorkbook(); 
        //Create file system using specific name
        FileOutputStream out = new FileOutputStream(
        new File("createworkbook.xlsx"));
        //write operation workbook using file out object 
        workbook.write(out);
        out.close();
        System.out.println("
        createworkbook.xlsx written successfully");
     }
