Multiple classes basics, putting a print class into the main method

I am trying to see the basics for what is required to call in a second class, because tutorials and the book I am using are over-complicating it by using user input right now.

So here is what I tried. First is my main class and the second is the class I tried to call into the main method portraying just a simple text.

public class deck {
    public static void main(String[] args) {
    edward test = new edward();
    System.out.print(test);
    }
}

Other class:

public class edward {
    public void message(int number) {
        System.out.print("hello, this is text!");   
    }
}

How come this doesn't work?

If you could try to explain what I am doing or how this works a bit in detail that would be nice. I'm having a hard time with this part and getting a bit discouraged.
