Lab Instructions: Object Oriented Programming

Tips: Before you Begin

To view your code and instructions side-by-side, select the following in your VSCode toolbar:

  • View -> Editor Layout -> Two Columns
  • To view this file in Preview mode, right click on this README.md file andย Open Preview
  • Select your code file in the code tree, which will open it up in a new VSCode tab.
  • Drag your assessment code files over to the second column.
  • Great work! You can now see instructions and code at the same time.
  • Questions about using VSCode? Please see our support resources here:
    Visual Studio Code on Coursera

To run your JavaScript code

  • Select your JavaScript file
  • Select the “Run Code” button in the upper right hand toolbar of VSCode.
    Ex: It looks like a triangular “Play” button.

Task 1: Code a Person class

  • Code a Person class, with three parameters in the constructor: name, age, and energy.
  • Set the default parameters in the Person class as follows:
name = "Tom"
age = 20
energy = 100
  • Code two methods in theย Personย class. Name those methodsย sleep()ย andย doSomethingFun().
  • Theย sleep()ย method should take the existing energy level and increase it by 10.
  • The doSomethingFun() method should take the existing energy level and decrease it by 10.

Task 2: Code a Worker class

  • Code a sub-class, inheriting from theย Personย class, and name itย Worker.
  • Theย Workerย class has two additional parameters in the constructor:
  • xp (for “experience points”)
  • hourlyWage.
  • These properties are set to the following default values:
xp = 0
hourlyWage = 10
  • Theย Workerย class has all the paramerters and methods of its super-class.
  • Additionally, it has theย goToWork()ย method, which, whenever it’s run, increases the value of theย xp property by 10.

Task 3: Code a intern object

  • Inside the intern function instantiate theย Workerย class to code a new intern object.
  • The intern should have the following characteristics:
name: Bob
age: 21
energy: 110
xp: 0
hourlyWage: 10
  • Run theย goToWork()ย method on the intern object. Thenย returnย the intern object.

Task 4: Code a manager object

  • Inside the manager function instantiate theย Workerย class to code a newย managerย object.
  • The manager object should have the following characteristics:
name: Alice
age: 30
energy: 120
xp: 100
hourlyWage: 30
  • Run theย doSomethingFun()ย method on the manager object. Thenย returnย the manager object.

 


 

Programming Assignment: Building an object-oriented program Solution

  • Copy & paste this code on ooprogramming.js File..
  • And save your file and then submit.
// Task 1: Code a Person class
class Person{
    constructor(name="Tom", age=20, energy=100) {
        this.name = name;
        this.age = age;
        this.energy = energy;
    }
    sleep() {
        this.energy += 10;
    }
    doSomethingFun() {
        this.energy -= 10;
    }
}

// Task 2: Code a Worker class
class Worker extends Person{
    constructor(name = "Tom", age = 20, energy = 100, xp = 0, hourlyWage = 10) {
        super(name, age, energy)
        this.xp = xp;
        this.hourlyWage = hourlyWage;
    }

    doSomethingFun(){
        super.doSomethingFun;
    }

    sleep() {
        super.sleep;
    }

    goToWork() {
        this.xp += 10;
    }
}


// Task 3: Code an intern object, run methods
function intern() {
    let intern = new Worker();
    intern.name = "Bob";
    intern.age = 21
    intern.energy = 110
    intern.xp = 0
    intern.hourlyWage = 10
    intern.goToWork()
    return (intern);
}

// Task 4: Code a manager object, methods
function manager() {
    let manager = new Worker("Alice", 30, 120, 100, 30);
    manager.doSomethingFun();
    return manager;
    
}

console.log(intern())
console.log(manager())
