我是 Selenium 和 Java 的新手。关于我的代码的基本思想是，我在我的 java 项目下创建了两个类，即第一个和第二个。我的第一个类包含所有方法（打开浏览器、登录、注销），我的第二个类包含从第一个继承所有方法的主程序。
我创建了一个 excel，说明应该根据 excel 表运行哪个测试用例（登录、注销）。测试用例将根据 Excel 表中“执行”列下的“Y”或“N”执行
当我尝试运行我的第二节课时，它显示了一个错误。请在下面找到我的代码以及错误和 excel 表作为测试用例应该运行的图像。
这是我的第二课（主程序）

Cell tableStart=sheet.findCell(tableName);
startRow = tableStart.getRow();
startCol = tableStart.getColumn();
Cell tableEnd = sheet.findCell(tableName, startCol+1, startRow+1, 100, 64000, false);
endRow = tableEnd.getRow();
endCol=tableEnd.getColumn();
System.out.println("startRow="+startRow+", endRow="+endRow+", " + "startCol="+startCol+", endCol="+endCol);

for (int j=startCol+1;j<endCol;j++,cj++) {
tabArray[ci][cj]=sheet.getCell(j,i).getContents();
}
}
return(tabArray);
}
}
