Why does this code throw an IOException?

Why does this code throw an IOException?

import java.io.File;
import java.io.IOException;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        try (Scanner scan1 = new Scanner(new File("File1.txt"));
             Scanner scan2 = new Scanner(new File("File2.txt"))) {

        } catch (IOException e) {
            System.out.println("An IOException has been thrown.");
        } 
        System.out.println("Done!");
    }
}

I am learning this from a book, but don't understand why it throws an exception. Any help is appreciated!

Because the constructor Scanner(File) throws a FileNotFoundException which is a sub class of IOException. Check the javadoc for more details.
