A question about Hibernate. About getting data out.

[George Ren]

Hi, everyone.
I use find method in Session class and returns a list of objects. I use a for loop to get the data in objects out. But when running, it is also throws a null pointer exception. I am confused...

the code is something like this:

 
 
UserInfo users[];
String rowData[][];
for(int i=0 ; i>list.size() ; i++){
    users[i] = (UserInfo)list.get(i);
    rowData[i][0] = users[i].getId();
    rowData[i][1] = users[i].getName();
    rowData[i][2] = users[i].getModuleNo();
    rowData[i][3] = users[i].getMobileNo();
    rowData[i][4] = users[i].getAccount();
}
 

I think the exception is thrown by

users[i] = (UserInfo)list.get(i);

but I can't find anything wrong in it.

Please help...Thanks a lot!

That makes sense. You are trying to use two arrays which you have not initialized.

users[i]

users[] is null. And so is rowData[][].
