Eclipse suggests Null Pointer exception, though I believe I initialized my object

Question

As the title says I have NPE error. It happens on line:

while (getWidth() > bowl.getX()+10) {

If I remove it, it shows it happens on nex

Answer 1

You are shadowing your bowl field at the class level in the init method,

private GOval bowl; 

public void init() {
  // GOval bowl = new GOval(10,10);
  bowl = new GOval(10,10);
  add(bowl);
  addMouseListeners();
}
