Example

• Full TestClothes code.
• Add the repl.it testing code starter to get the test going on Repl.it.

    // copy and paste? define public static void aassert(bool b)...true=ok, false=fail
    public static void main(String[] args) {
        Clothes hat = new HeadCovering(20, 105);
        Clothes underArmor = new WoolClothes (hat);
        Clothes denim = new HeadCovering(95,40);
        ArrayList<Clothes> w = new ArrayList<>();
        w.add(hat);
        w.add(underArmor);
        w.add(denim);

        Person p1 = new PlainPerson("Jane");
        aassert(50 == p1.getFashion());
        aassert(90 == p1.getWarmth());
        aassert("Jane".equals(p1.getName()));

        Person p2 = new BigFashionPerson("Sanjana", w);
        aassert("Sanjana".equals(p2.getName()));
        aassert(20+25+95 == p2.getWarmth());
        aassert(40 == p2.getFashion());
    }

Pedantic

An object that implements the Clothes interface has an integer value for its fashion level and its warmth rating. The methods in the Clothes interface are accessor methods that return those values.
