Codetown ::: a software developer's community
Hello all, I am “very” new to Java and fairly new to programming in general. I have been reading the “Head First Java” book and while doing one of the examples came across an observation. I created a colored circle and a button when you click the button the circle changes to a random color with the repaint() method. I have dual monitors set up and what I noticed was that If I were to drag the window to the second monitor it fires the repaint() method. Can anyone explain why this happens? I know this is probably something as a new programmer I don’t need to know right now but it did intrigue me so I thought I would ask.
