While using a boolean method, how do I add the String contents of a txt file into an array list

I am attempting to use the method "public boolean readArtists" with a scanner to read strings from a file and return true if opened successfully. This method is also supposed to "Adds to the list all of the artists stored in the file passed parameter."

I've seen how to write the code in a public static void method that will read the text file and return it:

public static void main(String[] args) {

	File file = new File("artists30.txt");

	String content = null;
	try {
		try (Scanner scanner = new Scanner(file, StandardCharsets.UTF_8.name())) {
			content = scanner.useDelimiter("\\A").next();
		}
	} catch (IOException e) {
		e.printStackTrace();
	}

	System.out.println(content);
}

Here is the test:

I have to keep the method "public boolean readArtists(String filename), so my question is, within this method, how do I read the contents of the text file into an ArrayList using a scanner, while also returning true if the file is opened successfully, Otherwise, handling the exception, displaying an appropriate error message containing the name of the missing file and return false.

You can achieve that using,

public static void main(String[] args) throws FileNotFoundException {
		String filepath = "C:\\Users\\Admin\\Downloads\\testFile.txt";
		List<String> arrayList = new ArrayList<>();
		
		if(readArtists(filepath)) {
			Scanner sc = new Scanner(new File(filepath));
			sc.useDelimiter("\\A"); 
			while(sc.hasNext()) {
				arrayList.add(sc.next());
			}
		}
		
		System.out.println(arrayList);
	}
	
	public static boolean readArtists(String filename)
	{
	   File file = new File(filename); //full path of the file with name
	   return file.canRead();
	}

public class Artists{
public static ArrayList<String> artists = new ArrayList<String>();
public static void main(String[] args) {
	System.out.println(readArtists("filename goes here"));
    System.out.println(artists);
}
public Artists(String artist, String genre)
{
}
public static boolean readArtists(String fileName) {
	
	Scanner sc = null;
	try {
		File file = new File(fileName);
		if(file.createNewFile()) {
			System.out.println("err "+fileName);
			return false;
		}
		sc = new Scanner(file);
		while(sc.hasNextLine()) {
			artists.add(sc.nextLine());
		}
	}catch(Exception e) {
		e.printStackTrace();
	}
	if(sc!=null) {sc.close();}
	return true;
}
}

This answer reads data from a .txt document into an ArrayList, as long as the .txt document names are on seperate lines in the document. It also outputs err \FILE\NAME and returns false if the document does not exist and true if it does. https://www.w3schools.com/java/java_files.asp is a great website to learn java by the way and this link brings you to the file handling page.
