Java arraylist question
This is a question on my homework, can anyone help me understand what it saying ? Thanks
"Suppose that you have an ArrayList and that it contains String objects. Which declaration of the ArrayList requires that objects retrieved using the get method be cast to Strings before calling a String method?"
Re: Java arraylist question
If you must cast to a String to use it as a String, then it must be a declaration that does not return a String object "as a String"
Re: Java arraylist question
I'm wondering...
That question would make a lot more sense if it asked how to declare an ArrayList so that things returned by get() do not have to be cast. (angle brackets)
Re: Java arraylist question
I get the impression that the multiple choice answers were left out
