我的任务
分享急！！调用构造器时候 参数无法进入函数的问题
这个方法 else 里面里面调用构造器的 在调用前 对数组 进行测试，数组是有值并且可以输出值的。从这里开始ao=new AuditOpinion(data); 遇到我现在困扰的问题
public List<AuditOpinion> resolverXLS(HSSFSheet hssfSheet){
//获取一个表格中的总行数 第一行得到的值是0 所以这里要+1
int allRow = hssfSheet.getLastRowNum()+1;
//获取一个表格中的所有列数 由于一些行 是合并单元格的，所以可能出现只有一行的情况
// 还有可能一行是空的，所以取所有行数里面最大的行数
int allCell = 0;
List<AuditOpinion> aduitList=new ArrayList<AuditOpinion>();
AuditOpinion ao=null;
for(int i=0;i<allRow;i++){
if(hssfSheet.getRow(i)!=null&&hssfSheet.getRow(i).getLastCellNum()>allCell){
allCell = hssfSheet.getRow(i).getLastCellNum()+1;
}
}
System.out.println("行数："+allRow+"，列数："+allCell);
//定义一个与 表格里面行数和列数 一样的字符串数组 用于储存解析好的数据
String[] data = new String[allCell];
//循环行
for(int n=3;n<allRow;n++){
//获取一行中的所有的数据 如果这一行是空 就不在执行里面的代码。
HSSFRow hssfRow = hssfSheet.getRow(n);
//不报错/*System.out.println(hssfSheet.getRow(0).getCell(1));*/
//报错/* System.out.println(hssfSheet.getRow(1).getCell(1));*/
if(hssfRow==null){
continue;
}
//循环这一行中的数据 如果这一行中的某一列是空的 就用“ ”代替
for(int m=3;m<allCell;m++){
if(hssfRow.getCell(m)==null){
ao=new AuditOpinion();
}
else {
//把表格中的数据存放到数组中
data[m]=hssfRow.getCell(m).toString();
System.out.println(data[m]+"!!!!"+data.length);
ao=new AuditOpinion(data);
}
}
aduitList.add(ao);
}
return aduitList;
}

解决了 ，基础问题错误了， 在循环里 new了 新的对象 每次循环都 new了一次，
传过去的数组 并不为空 数组里只有一个数

double.valueof这里，估计是数组里面的这个值是null

这个是报错，错误是这样的 在调用这个构造函数前，二维数组不为空的，但是调用后后，数组为空的 null

这个是类 里面有我 重载的构造方法； 上面那个参数为数组的调用方法 进入里面是一个空的数组
