Inheritance II

Inheritance II

In the last exercise, we created a parent class named Animal for two child classes named Cat and Dog.

The Animal class below contains the shared properties and methods of Cat and Dog.

 

class Animal {
  constructor(name) {
    this._name = name;
    this._behavior = 0;
  }

  get name() {
    return this._name;
  }

  get behavior() {
    return this._behavior;
  }   

  incrementBehavior() {
    this._behavior++;
  }
}

 

 

The code below shows the Cat class that will inherit information from the Animal class.

 

 

class Cat {
  constructor(name, usesLitter) {
    this._name = name;
    this._usesLitter = usesLitter;
    this._behavior = 0;
  }

  get name() {
    return this._name;
  }

  get behavior() {
    return this._behavior;
  }

  get usesLitter() {
    return this._usesLitter;
  }

  incrementBehavior() {
    this._behavior++;
  }
}

 

 

To the right, in main.js, you will put what you learned to practice by creating a parent class named HospitalEmployee.

 

---

class HospitalEmployee {
  constructor(name){
    this._name = name;
    this._remainingVacationDays = 20;
  }
  get name() {
    return this._name;
  }
  get remainingVacationDays() {
    return this._remainingVacationDays;
  }
  takeVacationDays(daysOff) {
    this._remainingVacationDays -= daysOff;
  }
}
