ImageIO cannot resolve to a type

Question

Just a simple programming question.

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;


public class ReadThePic {
    public static void main(String[] args){
        BufferedImage img = null;
        try {
            img = ImageIO.read(new File("strawberry.jpg"));
        } catch (IOException e) {
        }

    }
}

Error: ImageIO cannot be resolved to a type. Why?Thanks

import javax.imageio.ImageIO;

i tried it. imageio is fine now. Now i have the same problem for BufferedImage — Jürgen K., Oct 22 '15 at 14:17
Are you using OSGi or some other container technology? Or in other words, what is causing the *"restriction on the requiered library"*? — Harald K, Oct 23 '15 at 06:54
In java9, `javax.imageio` requires the `java.desktop` module. — Dávid Horváth, Nov 14 '20 at 15:50

try

Go to the Build Path settings in the project properties.
Remove the JRE System Library
Add it back; Select "Add Library" and select the JRE System Library.

or just do: Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning

you could have found the solution here: Access restriction on class due to restriction on required library rt.jar?

You forgot to import the class.
Add import javax.imageio.ImageIO after your other imports and it should work.
