Answer to Question #287919 in Java | JSP | JSF for Angge

Question

Construct a class to represent an air conditioning (AC) unit containing the following attributes

Input

The first input is an integer which will create an instance of an AC unit depending on the constructor used. This is specified below:

1 - construct an AC unit object via the default constructor (no

input needed)

2 - construct an AC unit object via the overloaded constructor

(a String for the brand followed by 1 (inverter type) or 0

(non-inverter type))

Then a number m is encountered which represents the number of operations that have to be invoked. This is then followed by an integer representing what operator to execute. The operators are specified below:

3 - calls power()

4 - calls thermostatUp()

5 - calls thermostatDown()

6 - calls temperatureUp()

7 - calls temperatureDown()

8 - calls getBrand()

9 - calls getType()

10 - calls getPower()

11 - calls getThermostat()

12 - calls getTemperature()

13 - calls display()
