If objects can't be passed....

Alright... I think I'm having another roadblock with the object/reference situation, but I'm not sure how to fix my syntax.... here's some code snippets.


and...


I also know that ArrayLists aren't IDEAL... but the use of an "ArrayList" is specifically asked for in this project.

The problem is I'm getting 2 compiler errors....
  • 1: line 28 createScore cannot be applied to Arraylist
    2: a warning about unchecked/unsafe operations in QuizGrader.


  • I think #1 has to do with me trying to send the ArrayList references to the ScoreIt class. Alright, I'm positive it does.... but what am I doing wrong??

    ... and I really thought I had it.

    When you do things right, people won't be sure you've done anything at all.

    I would say the object named key needs to be of the same type as the first parameter of method createScore()

    Whoppee!! I have some other issues, but this fixes my main issue.

    Guess I was closer than I thought.

    I agree. I always need to see examples to really "get it". I just wanted to point out he importance of the deeper understanding because I have seen some coworkers who took short cuts, slapped something together that worked just fine - until problems start. Then they waste so much time not really knowing what to look for to fix the problem because they never really understood their own code.
