I have the follwoing lines of code and am getting a NullPointerException
in the second line because i is null.
How will i call createImage so that i will have some value.

java.awt.Image i=this.createImage(800,1000);
Graphics g= i.getGraphics(); //null pointer here

I am new to swing and now just started writing code for this class.
Please help!

What is your createImage() method really doing?

I am in the process of testing something, and I need a graphics object to input as parameter in a method.
So to create that i have

java.awt.Image i=createImage(800,1000);
Graphics g= i.getGraphics();

Thank you!
