8.4 Choosing — implement two interfaces

Total: 0 / 3 pts

Practice mode — check each part and get hints as you go.

Task

Write Note that implements both interfaces. A class may implement as many as it likes, but must supply every method of each.

label() returns "Note: " plus the text; size() returns its length. The program prints Note: hello and 5.

Your solution

interface Printable {
    String label();
}

interface Sized {
    int size();
}

class Note implements Printable, Sized {
    // text field, constructor, then label() and size()

}

public class Main {
    public static void main(String[] args) {
        Note n = new Note("hello");
        System.out.println(n.label());
        System.out.println(n.size());
    }
}
