hi,

here you are trying to retrieve the list objects from the arraylist, that is not right, you are retrieving objects from the list,

so modify the line 10 as given below,

for (Object obj:getList()) //line 10
System.out.println(obj);
}

it's possible if for example your getList() method returns a "List of ArrayList"


but this is not your case..
