ImageIO 无法读取图像输入文件

Question

This is my first post. Excuse me if I'm making an obvious mistake.

BufferedImage img = null;

File file = new File("com/game/assets/badlogic.jpg");

try {
   img = ImageIO.read(file);
} catch (IOException e) {
    e.printStackTrace();
}

This is my code and it can't read my image input file for some reason. This is the error message:

javax.imageio.IIOException: Can't read input file!
    at java.desktop/javax.imageio.ImageIO.read(ImageIO.java:1308)
    at com.engine.Main.run(Main.java:41)
    at java.base/java.lang.Thread.run(Thread.java:844)
    at com.engine.Main.start(Main.java:32)
    at com.game.GameManager.main(GameManager.java:51)

I have no clue what am I doing wrong. Anyways Thank You, kind Strangers.

I got it to work!

BufferedImage img = null;

try {
   img = ImageIO.read(new FileInputStream("/Users/earmalys/Desktop/InteliJ projects/mantengine/src/com/game/assets/badlogic.jpg"));
} catch (IOException e) {
   e.printStackTrace();
}

But the file path is very exact. Is there anyway I can get around this?

Whenever I get a BufferedImage from a file, I find it much easier to use a FileInputStream rather than a File . Here's an example:

try {
    BufferedImage image = ImageIO.read(new FileInputStream("com/game/assets/badlogic.jpg"));
} 
catch (IOException e) { 
    e.printStackTrace();
}
