Need Java Assistance In Having The Test Below Run. Thank you

package hw;
	public class HelloWorld {
	public String getMessage() {
	return "hello world";
	}
	public int getYear() {
	return 2020;
	}
	}

package hw;
	import java.util.Arrays;
	public class Main {
	public static void main(final String[] args) {
	System.out.println("args = " + Arrays.asList(args));
	final var instance = new HelloWorld();
	System.out.println(instance.getMessage());
	System.out.println(instance.getYear());
	System.out.println("bye for now");
	}
	}
