Static reference to non-static method Error

Question

I cannot figure out what I have done wrong in the following code segment:

private Door openOtherDoor(Door prizeDoor, Door selectedDoor){
Door.setPrize(prizeDoor.doorPrize);
Door.open(selectedDoor.doorPrize);

I am getting the following error:

Cannot make a static reference to the non-static method open(boolean) from the type Door

Any help would be greatly appreciated

The method `open` is not static, but you are calling it from a static method. Change the method to `public static void open(boolean b)` — ruyili, Jan 31 '16 at 20:58
Almost certainly not. You should call `this.open()` instead of `Door.open()`. If you make it static you won't know which `Door` to open. @TheCoffeeKid — user207421, Jan 31 '16 at 21:29

if those methods are in the class Door, then you can do

private Door openOtherDoor(Door prizeDoor, Door selectedDoor){
Door.setPrize(prizeDoor.doorPrize);
Door.open(selectedDoor.doorPrize);

if setPrize is an static method, otherwise you will need the instance method i.e

private Door openOtherDoor(Door prizeDoor, Door selectedDoor){
    this.setPrize(prizeDoor.doorPrize);
    this.open(selectedDoor.doorPrize);

setPrize is in the class Door that why I am confused – Matteo Colombi Jan 31 '16 at 21:05
No, he can *not* do `Door.open(...).`. It's non-static. That's what the error message says, and it's what the question is about. – user207421 Jan 31 '16 at 21:30

According to error. You should define open method in Door class as static.
