The compiler doesn't understand what the real type of the object is unless you tell it, and that cast is basically the way to tell the compiler "even though you think To solve, use explicit imports: replace your import statements by import java.awt.Graphics; import java.awt.Graphics2D; import javax.swing.JFrame; import javax.swing.JPanel; This will tell the compiler which Graphics and Graphics2D do you mean.

Unfortunately, you can't call those methods through a variable of type "Graphics," simply because they're not part of that class. Very likely this is not an issue related to Graph module in NetNeans, therefore I am closing this issue as invalid. A cast of a reference variable (i.e., a variable that refers to an object) never changes the object -- it only changes how you can treat the object by providing additional http://electrictricycle.net/cannot-cast/cannot-cast-from-actionform.html As always, you guys rock here. :-D –Daniel Chateau Apr 13 '12 at 6:27 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up
