How come this isn't working

Question

I try to run this but it won't work.
cArray[0].scores[0] = (Double.valueOf(jtfQuiz2.getText())).doubleValue();
I am using 0 for the indexes just to see if I can get something in them. Then I try to see if anything has been put in them by calling :
jtfQuizAvg.setText(String.valueOf(cArray[0].scores[0]));
I declared an array of 50 objects like this.
CIS[] cArray = new CIS[50];
I have a class (CIS) in a package that I have imported. I am trying to get the scores of the individual tests in to the scores[] array found in that class I have imported.
CIS[] cArray = new CIS[50];
Please please help me!

Answer 1

Well, you don't say what your problem actually is, other than "it won't work", but one thing you should be aware of is thatCIS[] cArray = new CIS[50]; doesn't create an array of 50 CIS objects. Rather, it creates an array that can REFERENCE 50 CIS objects. You still have to create each object as you need it. So if you are getting a NullPointerException, that's because you needcArray[0] = new CIS(); before you use cArray[0].
