    Default [Solved]Pls check why my code is giving a runtime error

    My code compiles ok, but I get errors during runtime. I already spent hours on it but can't seem to figure out why. It is an animation. At first the code ran ok, but there was flickering so I tried to remove it, but when I tried to follow isntructions and remove the flickering of the animation, it gave runtime errors.

    Here is WORKING CODE of the animation but with flicker:
    Java | import java.awt.*; import jav - Anonymous - 5VwLgwrx - Pastebin.com

    Here is code with RUNTIME ERRORS, with attempts to remove flicker:
    Java | import java.awt.*; import jav - Anonymous - Fix4t20V - Pastebin.com

    EDIT: eclipse said that errors were coming from the update() and paint() methods

    You are getting NullPointerExceptions. Check your declaration of the Graphics object.

    I don't see anything wrong with it =( any hints?

    EDIT: I noticed that init() method was not even called, do you know where I could call it?

    EDIT2: Nevermind, solved it myself...
