Part (a)

Write Scoreboard class.

public class Scoreboard {
    private String team1, team2;
    private int score1, score2;
    private boolean team1Active;
    public Scoreboard(String team1, String team2) {
        this.team1 = team1; this.team2 = team2;
        score1 = 0; score2 = 0; team1Active = true;
    }
    public void recordPlay(int points) {
        if (points > 0) {
            if (team1Active) {
                score1 += points;
            }
            else {
                score2 += points;
            }
        } else {
            team1Active = !team1Active;
        }
    }
        public String getScore() {
        return score1 + "-" + score2;
    }
}

Track scores and active team.

// points > 0: add to active team
// points == 0: switch active team
