    Default null pointer exception

    HTML Code:
    public class Selection {
    private Vector<Cue> cuevalues; // vector of Cues
    public Selection()
    	int count = 0;
    	System.out.println("I AM HERE");
    while (count < 16)
    	System.out.println("I AM HERE YO");
    	Cue cue1 = new Cue(PrintColumns.cuevalue(count), count);
    	System.out.println("I AM HERE jeez");
    	System.out.println("I AM HERE please");
    	System.out.println("I AM HERE " + count);
    I am running this code through the constructor and am getting a null pointer exception when adding a Cue object into a vector of Cues.

    Does anyone know why this could be happening?

    Obvos forget the Printlines.
