We encounter problem when using
, anyone can help?
In JFrame1, we use
to show an
(says, C:\abc.jpg with an apple) on
It shows Apple on the Jbutton.
We then update abc.jpg. (says, copy C:\def.jpg with an orange to C:\abc.jpg)
So, we check in Windows, both abc.jpg and def.jpg are orange now.
But when we load again JFrame1, the image on
is still show apple.
We expect it is an orange.
So, we close the apps and start again.
Now, it shows orange.
We use ImageIO.read to read the image to
and use it in construct
It seems that
cache the image and does not reload it.
How can we clear the cache and force
to load the latest image?
It is sorta covered in the
