Lab 3

Description

In this lab you I have recreated Lab #2 using inheritance. First, I created a class and name it Sensor. The Sensor class contains a single private field element, a variable int reading. The Season class also contains following setter and getter methods: setReading, getReading. The Method setReading() generates random values between 0 and 100 and sets that value to the reading variable. The getReading() method always retrieves the last value stored on the reading variable. I have also created 2 more setReading() methods this is called overloading.

I’ve created the  setReading( int u) that generates values between 0 and the set number U. The seconded overloaded method setReading( int l, int u) generates values between l and u which counts for the inclusive range. I also created another class called TemperatureSensor that inherits class Sensor and implements the following methods: getWinterTemp, getSpringTemp, getSummerTemp, getFallTemp. These methods all generate a set inclusive range of temperature. getWinterTemp returns a number between 20-40, getSpringTemp between 40-70, getSummerTemp between 70-90, and getFallTemp between 40-60. These methods use the overloaded method setReading(int l, int u) to set the range and the  super.getReading() as the return statement of methods appropriately.

The third class I created was the HumiditySensor Class that inherits from the  class Sensor and  implement the following methods: getHumidity, getLowHumidity, getHighHumidity. The methods of this class all return a range a number. getHumidity returns a number between 0-100, getLowHumidity between 0-50, getHighHumidity between 50-100. These methods use the all 3 of the setReading() methods in class Sensor. they are refer to by the super. keyword and all use the getReading() method to retrieved the value for reading respectively.

The last class SensorsStatsApp is the Driver class for this program and it implement the application. In the application I display a menu that will first ask the user what season they would like to simulate[1] winter [2] spring [3] summer [4] fall [5] random [6] exit. In this program there is a new option called Random that will choose a season for the user at random.Another menu that is new to this application will ask the user what type of humidity they would like to simulate [1] full range [2] low [3] high [4] random [5] exit. Again the Random option will select a type of humidity for the user at random. Once the user has made their selection the prompt will now ask the user how many simulations to generate. Each simulation will call the corresponding method from the TemperatureSensor and HumiditySensor. At the end of the program it display a summary.

CODE:

public class Sensor {
	//Fields
	private int reading;

	//Methods
	public void setReading(){
			this.reading = (int)(101*Math.random()); //sets reading 0 - 100
	}
	public int getReading(){
			return this.reading;
	}

	//overloaded Methods
	public void setReading(int u) {
			int limitU=u+1;
			this.reading = (int)(limitU*Math.random()); //sets reading 0 to u
	}
	public void setReading(int l, int u) { //sets reading l to u
		int limitU = u+1;
		int limitL = l+1;
		int value;
		do{
			value = (int)(limitU*Math.random());
		}while((value<l)||(value>u)); //will ensure only values from l to u inclusive will be produce
		this.reading = value;	
}
}
