Why can't I move the horizontal line up in my java code. Line line$11=$ new Line$(-$x $/2\mathrm{.}5,-$x $/2\mathrm{.}5,$ x $/1\mathrm{.}5,-$x $/2\mathrm{.}5)$;

Line line$12=$ new Line$(0,-$x$,0,$ x$)$;

line$11.$setStroke$($Color$.$GREEN$)$;

line$11.$setStrokeWidth$(5)$;

line$12.$setStroke$($Color$.$GREEN$)$;

line$12.$setStrokeWidth$(5)$;

$//$StackPane to hold the lines

StackPane lines $=$ new StackPane$()$;

lines.getChildren$().$addAll$($line$11,$ line$12)$;

$//$GridPane for layout

GridPane pane $=$ new GridPane$()$;

pane.setPadding$($new Insets$(50,50,50,50))$;

pane.add$($lines$,2,2)$;

pane.add$($angle$,0,0)$;

pane.add$($c$,1,1)$;
