我的数组只存储值直到迭代运行..在完成值的存储并尝试获取这些值后，它返回Null值并尝试了这么多次以及很多方法来获取值但是我没有用尝试...最后我最终得到了堆栈溢出网站。我希望我的等待在这里结束
public class RegisterUser extends BrowserInit{
public String[][] values;

//Clicking Login link in WebPage

//moving the cursor to element and clicking on the link

//after clicking on the link checking is their any new tab is opened

答案 0 :(得分：0)
您每列创建一个新数组，基本上可以删除之前存储的内容。
for(/*alltherows*/){
for(/*all the columns */){
//THIS IS YOUR ERROR!! You're creating a new array, and storing it in values
values=new String[data.sheet.getLastRowNum()+1][data.sheet.getRow(row).getLastCellNum()+1];
//Now you're putting a value in one spot on the array
values[row][col]=data.sheet.getRow(row).getCell(col).getStringCellValue();
}
//data access stuff
}
解决方案是在for循环之外创建数组。如果您的所有行都具有相同数量的列，则可以对您要查看的行进行硬编码：
//create a new array before you use it
values=new String[data.sheet.getLastRowNum()+1][data.sheet.getRow(1).getLastCellNum()+1];
for(/*alltherows*/){
for(/*all the columns */){
//Now you're putting a value in one spot on the array
values[row][col]=data.sheet.getRow(row).getCell(col).getStringCellValue();
}
//data access stuff... NO LONGER NULL :)!!
}
一些进一步的想法......如果你只是每行访问数据，那么多维数组就会变得不必要了。试着弄清楚是否可以将其更改为一维数据结构以满足您的需求。它将为您和其他需要解释代码的人带来麻烦。
