I declared an ArrayList
as follows (as I use to declare it) and then set its content. However, a notice message that I am not using declared "al"
variable. It doesn't dissapear although I use it at following line. Content is also not set! Strange... why? Thank you
ArrayList<String> al = new ArrayList<String>();
al = parsedExampleDataSet.getView();
It means you are setting it but never reading it.
Apparently, you never access al except to assign it.
Also, you are creating a new ArrayList, and then discarding the object when you reassign it to parsedExampleDataSet.getView()
. This probably has nothing to do with your error, but it's a waste.
try this:
ArrayList<String> al = null;
al = parsedExampleDataSet.getView();
