Hi, I need to get this assignment done for my Business Application Development Class by tonight.

The Language is Java, I have attached the assignment on here for you to see.

 

In this assignment you will model a home automation light controller that can turn on and off individual lights in a building. The controller will be an object that will have public methods to control the lights. The lights will in turn also be objects created from the Light class. A simple driver program will demonstrate the use cases of the controller.

 

1) Create a new Project. Add new class files for Light and Controller.

 

2) Light class: a) private attribute boolean isOn b) private attribute boolean isDefective c) private attribute int brightness d) private attribute double defectRate e) a default constructor that will i) set brightness to 255, turn light off and set defective to off ii) generate a random number between .05 and .15 and assign it to defectRate Hint: use Random's nextDouble() method that returns a number from 0.0 to 1.0. Get this number to the desired range of .05 to .15 by dividing it by 10 and adding an offset of .05. f) private method boolean isBurningOut() that simulates the probability of the light burning out when turning on. It should return true if the light is already defective. Otherwise it should generate a random number from 0.0 to 1.0 (with nextDouble()) and compare it to the defectRate. If the random number is less than defectRate, the light will burn out, so the method should return true. Otherwise it should return false. g) public method void turnOn() that attempts to turn on the light. It should check with the isBurningOut() method and then set the light's isOn to true if it is not burning out, otherwise, it should turn the light off and mark it as defective. h) public method void turnOff() that turns the light off. i) public method void setBrightness(int desiredBrightness) that checks the parameter for being in allowable range and sets the light brightness to the desired value. If the parameter is less than 0 or more than 255, set it to 0 or 255, respectively. j) public method char getStatus() that returns a character 'o' if the light is on with brightness less than 128, 'O' if it is on with brightness 128 or more, and dot '.' if the light is off.

 

3) Controller class: a) private array Light[] lights that holds the references to light objects b) a constructor that takes one parameter numLights that indicates how many lights are controlled by the controller i) it dimensions the lights array to size numLights ii) it creates new lights objects and stores them in the lights array (use a for loop) c) public method void printStatus() that goes through the lights array and prints the status of each light on one line. Afterwards it prints a newline to move the printing position to the next line. d) public method void turnLightOn(int lightid) that turns on the indicated light and calls printStatus() e) public method void turnLightOff(int lightid) that turns off the indicated light and calls printStatus() f) public method void setLightBrightness (int lightid, int intensity) that sets the brightness of the indicated light to the desired intensity and calls printStatus() g) public method void turnAllOn() that turns all the lights on and calls printStatus() h) public method void turnAllOff() that turns all the lights off and calls printStatus() i)

 

4) Driver program: a) Instantiate one controller object with 20 lights. b) perform the operations as described in the Requirements section.

 

ISM3230Individual Assignment 5–ClassesSpring 2017In this assignment you will model a home automation light controller that can turn on and off individuallights in a building. The controller will be an object that will have public methods to control the lights.The lights will in turn also be objects created from the Light class. A simple driver program willdemonstrate the use cases of the controller.Requirements:Light class:The light class represents an individual light. A light can be defective or functional, if it is not defective, itcan be on or off (when defective it is off), and has a brightness ranging from 0 to 255. The brightnesslevel is remembered even when the light is off, so when it is turned on again it has the saved brightnesslevel. Finally, each light has a random defect rate that ranges from 5% to 15% (exaggerated for thisexercise).When a light object is created, the light is off, not defective, brightness is set to full and a random defectrate is set. A light can be turned on, turned off, and the brightness can be set from 0 to 255. When thelight is being turned on, there is a chance that the light will burn out and consequently will beimmediately turned off and marked as defective. A light can indicate its status by returning a characterto the caller: a dot '.' means off, 'o' means on with intensity <128, and 'O' means on with intensity>=128.Controller class:A controller controls a number of lights. When a controller is created, it must be given the number oflights it will contain. The controller will create the required number of the lights and save theirreferences in an array. The controller has several actions it can perform with the lights. It can turn all thelights on, all the lights off, individual light on (as indicated by a parameter that is the index into the lightsarray), individual light off, and it can set the brightness of a specific light.For the purposes of this simulation, the controller prints out the status of all the lights after every actionthat affects any of the lights. The controller asks each light for its status character and prints the wholeset of lights in one line after a light is turned on, off, or the brightness is changed.The driver program:This is the testing program for the controller. It contains the following actions:it creates one controller with 20 lightsit cycles all the lights on and off four timesit turns light 5 onit sets the brightness of light 5 to 20it sets the brightness of light 10 to 100it turns light 10 on
