module HelloWorld {
    
    requires java.desktop;
    exports helloworld;
    
}

 

Because it requires java.desktop, therefore we can use BufferedImage class:

Greeting.java

package helloworld;

import java.awt.image.BufferedImage;


/**

public class Greeting {
    
    BufferedImage image;

    public static void main(String[] args) {
        System.out.println("Hello world");                
    }
    
}
