Java：使用ImageIO写入图像文件

Question

My code looks as so:

    File saveLocation = new File("src\\database\\images\\");
    ImageIO.write(this.image, "jpg", saveLocation);

And my error is this:
java.io.FileNotFoundException: src\\database\\images (Access is denied)

images is a folder in my netbeans project
I can read from it just fine.

Answer 1

Two things

1. src\\\\database\\\\images\\\\ is likely a directory, you need to supply a file name for the image, something like src\\\\database\\\\images\\\\Output.jpg for example
2. You shouldn't be referencing the src directory, ever. Instead, you need to save the file somewhere the file system. You could use ./Output.jpg for the current working directory (which is typically the project directory)

Answer 2

Ummm. That's a directory... how could you read from it just fine? All I notice is that you are missing a file name.

 File saveLocation = new File("src/database/images/myImage.jpg"); // <-- Use `/`.
