8.2 Comparable — make a class comparable

Total: 0 / 3 pts

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

Task

Complete Player so that it implements Comparable<Player>, ordering players by score, lowest first.

The program prints true twice: Ada scored more, so she comes later.

Return the sign — the exact number does not matter.

Your solution

// The class below must be made comparable by score.

class Player implements Comparable<Player> {
    private String name;
    private int score;

    public Player(String name, int score) {
        this.name = name;
        this.score = score;
    }

    // write compareTo here

}

public class Main {
    public static void main(String[] args) {
        Player a = new Player("Ada", 90);
        Player b = new Player("Bo", 55);
        System.out.println(a.compareTo(b) > 0);
        System.out.println(b.compareTo(a) < 0);
    }
}
