null in paint method of layer manager

[sgadhvi]

sorry for posting in wrong section, but its urgent and I think more people are involved into this section that's why im posting.

while developing one strategy game , in the later rounds I get null pointer exception in the layermanager.paint method.
below is the code

if(g==null){
        System.out.println("new graphics");
         g=getGraphics();
      }
    if(layerManager==null){
         System.out.println("new layer manager");
         layerManager=new LayerManager();
     }
    layerManager.paint(g, 0, 0);

even if I create new objects of graphics and layer manager in case if they are null. I am getting null pointer in paint method. what can be the reason
can somebody give some suggestions.
