           Sheet sheet = wb.getSheet(0);
           int columns = sheet.getColumns();
           int rows = sheet.getRows();
           
           System.out.println("No of Columns-->"+columns);
           System.out.println("No of rows-->"+rows);
           
           String data;
           for(int row = 0;row < rows;row++) {
               for(int col = 0;col < columns;col++) {

                   if(col>0)
                   System.out.print(", ");
                   System.out.print(data);
               }
               System.out.println("");
           }
