Can you check whats wrong with my code? :     package readexcel;

    import java.io.File;
    import jxl.Cell;
     import jxl.Sheet;
     import jxl.Workbook;
    import org.apache.poi.hssf.usermodel.HSSFCell;

    public class ReadExcel {

    public static void main(String[] args) throws Exception 
    { 
        File f=new File("C:\\Users\\user1\\Desktop\\203132017.xls");
    Workbook wb=Workbook.getWorkbook(f);
    
        Sheet s=wb.getSheet(0);
        int row=s.getRows();
        int col=s.getColumns();
        HSSFCell cell;
            
    for (int j=0;j<200;j++){    
    
    Cell c=s.getCell(10,j);
    c.getContents();       
     c.setCellType(HSSFCell.CELL_TYPE_NUMERIC);       
    }}}
