So I have googled some minutes how to use the timer and found some helpfull threads here. But when I want to use the suggested code Eclipse shows me always an error.
Import javax.swing.Timer not java.util.Timer.
Swing Timer has a constructor Timer(int , java.awt.event.ActionListener).
take a look at your imports. Eclipse has auto imported java.util.Timer. Change that to javax.swing.Timer and you should be on your way.
your import is wrong there correct that
change
java.util.Timer
to
javax.swing.Timer
