No! not 'etc.....', but the exact line-number, and the name of the missing/ misspelled method!

Aren't you missing some 'extends JFrame' or something like that?

is your code and the stack trace a direct copy/paste?

because your code has a method
createAndShowGUI()

but your stack trace reports
HelloWorldSwing.createandshowgui

...which is accurate...you have no method createandshowgui()
