Hello,

we have to make a simple program for college with JFrame and JPanel... The
window appears and some lines are drawn, but still there is a problem - when
i update the code and recompile and run the program again, the old picture
is still there.

What do i have to do so the new things will appear? Perhaps some refresh(),
reload()... since this is a sample code our teacher gave it should work,
perhaps it is just OS problem.

WinXP, Java SDK 1.4.2

Any help will be very appreciated.
