Description
某系統會發送不同類型通知：
EmailNotification 為 Email 通知，SMSNotification 為簡訊通知、AppNotification 為 App 推播通知。
請使用多型 (Polymorphism) 管理所有通知。
Requirements
第一行輸入通知數量 n，接著輸入 n 筆通知資料：
| 類型 | 格式 |
|---|---|
| EmailNotification | EmailNotification user |
| SMSNotification | SMSNotification user |
| AppNotification | AppNotification user |
需使用物件：Notification[] notifications
且每個子類別需 Override：send()並依序輸出通知結果。
Output
| 類型 | 輸出格式 |
|---|---|
| EmailNotification | Send EMAIL to user |
| SMSNotification | Send SMS to user |
| AppNotification | Send APP to user |
Hint
class Notification {
protected String user;
public Notification(String user) {
this.user = user;
}
public void send() {
System.out.println(user);
}
}
子類別可透過 Override 改寫：
@Override
public void send() {
System.out.println("Send EMAIL to " + user);
}
