1.ある会社のために従業員給与支払プログラムを作成すると仮定し、この会社には様々なタイプの従業員(Employee)があり、異なるタイプの従業員は異なる方法で給与を支払う.
(1)マネージャー(Manager):毎月一定の給料をもらう
(2)販売員(Salesman)--基本給に加えて毎月販売収入がある.
(3)一般労働者(Worker)--毎月働いている日数で給料を計算します.
これらの機能は、上記の要件に従ってクラスの継承と関連メカニズムを試用して説明し、Javaアプリケーションプログラムを作成し、これらのクラスの使用方法を実証します.(ヒント:従業員クラス(Employee)は、すべての従業員の共図特性を記述するように設計する必要があります.このクラスは、賃金を計算する抽象的な方法ComputeSalary()を提供し、このクラスを通じてすべての従業員の賃金を計算できるようにする必要があります.マネージャ、販売担当者、一般労働者に対応するクラスは、このクラスを継承し、給与の計算方法を再定義し、具体的な実装を行う必要があります.)
2.Java Applicationプログラムを作成し、プログラム実行時に1~100の乱数を自動的に生成し、ユーザーのキーボード入力データを受信し、推測するまでヒント情報を与える設計目標を実現する.プレイヤーが当てた後、推測回数を表示し、「再開」と「終了」機能を提供します.
