getResourceAsStream returning null

问题

I've seen many other people ask this question here and here, but it seems that I have done everything necessary yet I still get null when using the getResourceAsStream() call.

In netbeans I dragged my image into my package and it shows up in the folder in which the source code and .class files are held. So I have: src\com\myProject\ClassIMakeTheCallFrom.java src\com\myProject\MyImage.png

also a similar structure exists in: build\classes\com\myProject\ClassIMakeTheCallFrom.class build\classes\com\myProject\MyImage.png

However when I make the call:

System.out.println(dolphinWater.class.getClassLoader().getResourceAsStream("myImage.png"));

It comes out null. Am I missing something?

回答1:

Either put the file directly in the src folder, not the package folder. Or use getResourceAsStream("com/myProject/myImage.png").
