Programming Assignment 1 – The Smart Home
Let’s get your Java foundations solidified by examining a real house…
the house of the future! In this exercise, imagine you’ve been tasked
with creating a system that coordinates all the elements of a “Smart
Home.” These are homes that have built-in automation that handles
the lighting, temperature, entertainment, and myriad appliances to
make your life easier and more efficient. Not only are these things
controlled remotely, but they often work together for a more
seamless experience.
Start first by creating a new class called SmartHome.java. Inside your
main function, you should do the following:
Accept user console input. It should take in the following commands:
• “Change temperature”
• “Play music”
• “Stop music”
• “Turn on television”
• “Turn off television”
• “Turn on light”
• “Turn off light”
• “Make a call”
• “Answer doorbell”
• “Close system”
Create instance variables that represent the following (use appropriate data types):
• Temperature
• A/C setting
• Is music playing? (yes/no)
• Is the television on? (yes/no)
• Music track selected
• Television channel selected
• Room light settings
Here are some requirements about how your system should operate:
• When a user enters a command, the program should provide confirmation that the command
has been executed
• Set the appropriate variables to the corresponding user input
• If the user is changing the light, ask him/her which room it should be for. Track the light in the
following rooms (bedroom, kitchen, living room, bathroom, garage)
• If the user is changing the temperature, ask him/her what temperature he/she would like. If the
new temperature is higher than the previous, put the A/C setting at “heat.” If the new
temperature is lower than the previous, put the A/C at “cool.”
• If the user is changing the music, ask him/her which song he/she would like. Create a text file
called “songs.txt” that has at least five different songs. Read the file list and check if the user’s
request is there. If it isn’t, tell the user what songs are available. If it is, begin playing that song
• If the user is turning on the TV, ask him/her which channel he/she would like. Create a text file
called “channels.txt” that has at least five different channels. Read the file list and check if the
user’s request is there. If it isn’t, tell the user what channels are available. If it is, turn the TV to
that channel
• If the user makes a call, turn off any electronics that are providing audio. Ask the user what
number he/she wants to call. If the number is not a 10-digit number, tell him/her the format
was incorrect and to try again
• If the user answers the doorbell, turn off any other audio. Ask the user to input a message to
send to the person waiting at the door
• If the user requests the television be turned on, provide a follow-up question: “Would you like
the lights dimmed?” If the living room lights are on, turn them off.
• Create a method that shuts the system down. This will be called when the user says, “Close
system.” It will reset all room settings and turn off any appliances. (Imagine this happening
when the owner leaves for the day)
To get you started, here’s a simple framework that will continuously read input until the user shuts
down the system. You are welcome to expand from here:
Include appropriate comments throughout your code. Remember to use standard Java naming
conventions. For reference, check out:

Put your name and information about the program at the beginning of your program. Submit your
SmartHome.java, SmartHome.class, and a screenshot of it in operation on your computer. Package all
of these in a zip file and name the submission in the format:
NAME_COURSE_ASSIGNMENT_DATE.zip
Submission is due by 11:59 p.m. ET.
