使用 Helper 类简化复制粘贴过程

Question

我正在做一个项目，我有一个问题。 我在 50% 的课程中​​使用此代码。

public sendMessage disableNotification(boolean disableNotification) {
    this.disableNotification = disableNotification;

    return this;
}

是否有一种带有假设类Helper的继承方法，允许我只编写一次该方法？

每个类中唯一改变的是对象。 例如，这是sendMessage其他人可以是sendAudio 。 我可以简化这个复制粘贴过程吗？

Answer 1

我猜你正在寻找抽象类。

abstract class  Helper {
    private boolean disableNotification;

    public Helper disableNotification(boolean disableNotification) {
        this.disableNotification = disableNotification;
        return this;
    }
}

class sendMessage extends Helper {

}

class sendAudio extends Helper {

}

class Test {
    public static void Test() {
        Helper sendMessage = new sendMessage();
        Helper helper = sendMessage.disableNotification(true);
    }
}

Answer 2

abstract class Helper {
  private boolean disableNotification;

  public Helper disableNotification(boolean disableNotification) {
    this.disableNotification = disableNotification;
    return this;
  }
}

class sendMessage extends Helper {
}

class Test {
  public static void Test() {
    Helper sendMessage = new sendMessage();
    Helper helper = sendMessage.disableNotification(true);
  }
}
