インタフェースで、簡単なゲームを書きます.

roleインタフェース:キャラクタ攻撃と修練

  public interface Role {
    int attack();//    ，           
    void practise();//     。             
}

MagicStickインタフェース:法師用の杖

public interface MagicStick {
    int fire();
}

Weaponインタフェース:戦士に適した武器

public interface Weapon {
    void setSoldier(Soldier s);//              
    int fire(); //                 ，       
}

法師が使っている2種類の杖類

public class GreenStick implements MagicStick {
    //      
    Calendar calendar = Calendar.getInstance();
    //      
    int month = calendar.get(Calendar.MONTH)+1;
    /**
     *            
     *           （6-8）   ：2；
     *            ：1
     */
    public int fire() {
        if(month >=6 && month <=8){
            return 2;
        }else {
            return 1;
        }
    }

public class BlackStick implements MagicStick {
    Calendar calendar = Calendar.getInstance();
    int month = calendar.get(Calendar.MONTH)+1;

    @Override
    public int fire() {
        if(month % 2 == 0){
            return 2;
        }else {
            return 1;
        }
    }

法師類:法師の基本的な情報

public class Magicer extends NamedRole {

    private MagicStick stick;

    /**
     *       
     *            *5
     */

    @Override
    public int attack() {
        return level * 5;

        //     stick  ，     +1
        //     ，    ：    +1+stick   fire      
        if(stick == null){
            level++;
        }else {
            level = level + 1 + stick.fire();
        }
    }

    public Magicer(String name, MagicStick stick, int level) {
        super(name);
        this.stick = stick;

    }

    public void setLevel(int level) {
