I just need a good explanation for the following lines: Workbook wb = WorkbookFactory.creatr (); Sheet s = wb.getSheet ("sheet name"); specially this sector Sheet s = wb.getSheet what is the relation between Sheet and wb? Also, does Sheet is a pre-defined class and we make an instance of it as " s " furthermore, Is wb.getSheet is a method "getSheet" inside class wb or what Thanks in advance. | 0 |
