# Use getters and setters to Control Access to an Object

## Problem Explanation

Getters and setters are critical parts of a class/object. They allow you to control their attributes from the outside. They will become more prominent when you get started with the Object-Oriented Programming unit (coming up!). For now, this exercise shows you how to manipulate them with ES6.

## Hints

### Hint 1

Create the class, Thermostat. You’re going to put your constructor, getter, and setter in here.

### Hint 2

Give the constructor a parameter (which you can name anything you want). Set the parameter to an attribute of the same name. Remember, you are initially setting things in Fahrenheit temperature.

### Hint 3

Create a get method that converts the Fahrenheit attribute to Celsius. Use the formula given to you.

### Hint 4:

Create a set method of the same name as the get method. It should have a parameter that accepts celsius temperature. Convert it to fahrenheit, and set it to the attribute.

## Solutions

Solution 1 (Click to Show/Hide)
``````class Thermostat {
constructor(fahrenheit) {
this.fahrenheit = fahrenheit;
}

get temperature() {
return (5 / 9) * (this.fahrenheit - 32);
}

set temperature(celsius) {
this.fahrenheit = (celsius * 9.0) / 5 + 32;
}
}
