Including Images with an executable jar
Files in a Jar are not files in the sense of a file on disk. They are simply a (possibly) compressed stream of bytes.
Java makes it easy to extract these "resources" from Jar files through the use of the ClassLoader
background = ImageIO.read(getClass().getResource("/wood.jpeg"));
Should work...
This will return a URL which ImageIO can use to load the resource.
You could also have a read of
- Classpath resource within jar
- Jar get image as resource
- Load a resource in Jar
And I could list some more. So, yeah, it gets asked a lot ;)
