Generics are not supported

Question

Using Java Studio Enterprise 8.1.
1. Have following code inside class MPoll.java:
public class MPoll {
private Vector<MQuestion> q;
line selected in IDE as wrong with message: "generics are not supported in -source 1.4 (try -source 1.5 to enable generics)
2.
private MQuestion questions[];
Following code throws NullPoinetrException:
MQuestion x = new MQuestion();
int i = 0;
questions(i) = x; // Exception here
3. Following code throws NullPointerException too:
questions(i) = new MQuestion(); //Exception here
object x created correctly.
The task is to create analog of C++ vector<MQuestion>...

1. So change your compiler settings accordingly. How to do that would be written in the manual or help, or can be asked at the forums here: http://forum.java.sun.com/index.jspa?tab=devtools
2. questions(i) = x; is no valid code.
3. questions(i) = new MQuestion(); //Exception here
is no valid code either.
Neither would throw an NPE. Please post the real code, formatted.
