Question

I have JPanel Which will load images.

Since images will not have the same width and height as the JPanel, I want to make the image resize and fit in the JPanel.

Answer 1

Read on this article, The Perils of Image.getScaledInstance()

Now IF you STILL prefer you can use something like,

Image scaledImage = originalImage.getScaledInstance(jPanel.getWidth(),jPanel.getHeight(),Image.SCALE_SMOOTH);

this before loading the image to your JPanel, probably like discussed in this answer.
