How to add image path in java

You should not load images from the file system but simply bundle it into the app. If you have placed the images inside the app in the package com.bar.resources for example, you simply need to use

To load the image as an input stream.

If you have placed the images inside the package in your java source code directory then the class loader will load the images automatically while compiling by just copying to the same folder as the generated .class files.
