Question

Using Eclipse IDE. The line:

getClass().getResource("/res/bitmaps/image.png");

returns null. I have created the res folder in the root of my project.

The code of interest is:

bImage = ImageIO.read(getClass().getResource("/res/bitmaps/image.png"));

and it throws the exception:

Exception in thread "main" java.lang.IllegalArgumentException: input == null!
    at javax.imageio.ImageIO.read(ImageIO.java:1378)
    at com.example.game.resource.Resources._loadImage(Resources.java:31)
    at com.example.game.GameComponent.<init>(GameComponent.java:19)
    at com.example.game.GameFrame.<init>(GameFrame.java:8)
    at com.example.game.GameFrame.main(GameFrame.java:13)

Any help?

Answer 1

ImageIO.read(getClass().getResourceAsStream("res/drawable/image.png"));

Make sure res folder is in class path, verify using project properties > Java build Path > Source tab. If not in class path, can add via Add Folder.. button on the right.
