how could i create lines by using array? javafx

Question

I am trying to create some lines by using an array but i couldn't complier it. just gives me several exceptions.

Anyone could help me with the idea?

public class Dotgame extends Application {

@Override
public void start(Stage primaryStage)
{

//creating array of circles;
Circle[] circle=new Circle[9];
Line[] line=new Line[12];

int cCount=0;
int lCount=0;

//assign the lines
for(int i=0;i<9;i++)
{
line[i].setStartX(circle[i].getTranslateX());
line[i].setStartY(circle[i].getTranslateY());
line[i].setEndX(circle[i+1].getTranslateX());
line[i].setEndY(circle[i+1].getTranslateY());
}

//assign the size of circles;
for(int i=0;i<9;i++)
{
circle[i]=new Circle(10);
}

//assign the X,Y of the circles;
for(int i=100;i<400;i+=100)
{
for(int j=100;j<400;j+=100)
{
circle[cCount].setTranslateX(i);
circle[cCount].setTranslateY(j);

cCount++;

}

}

Group group=new Group(line);

StackPane root = new StackPane();
root.setAlignment(Pos.TOP_LEFT);
root.getChildren().addAll(circle);
root.getChildren().addAll(line);

Scene scene = new Scene(root, 500, 500);

primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}

}

Please post those 'several exceptions'. This could help to understand your problem.
