LAB 3 – INHERITANCE

LAB 3 – Inheritance

Lab Description:

In this lab, we will be recreating the Temperature sensor from lab 2 but with the help of inheritance. This application will be compromised of four class java files in total which are Sensor.java, TemperatureSensor.java, HumiditySensor.java, and SensorStatsApp.java. The Sensor class will contain the set/get reading methods which will be in charge of generating the random values from within the provided ranges by the user through the use of overloading methods. The TemperatureSensor class will be inheriting from the Sensor class and will contain the get methods that obtain the random temperature readings for the desired season within the provided range by calling the methods from its superclass. The HumiditySensor class will also be inheriting from the Sensor class and will contain the get methods for the selected humidity range and will be making use of the overloaded methods in the superclass. The SensorStatsApp will be the main application file. This will contain the Main Menu of the application which will ask the user for the season, humidity range, and the repetitions as well as contain the code that will be used to calculate and display the required outputs to the user. Like in the past, try and catch statements will be used to verify for valid inputs by the user.

Code:

Sensor Class Code:

public class Sensor {

	private int reading;

	public int setReading()
	{
		return reading = 0 + (int)(Math.random() * ((100 - 0) + 1));	
	}

	public int setReading(int u)
	{
		return reading = 0 + (int)(Math.random() * ((u - 0) + 1));	
	}

	public int setReading(int l, int u)
	{
		return reading = l + (int)(Math.random() * ((u - l) + 1));
	}

	public int getReading()
	{
		return reading;	
	}

}

TemperatureSensor class code:

public class TemperatureSensor extends Sensor{

	private int u;
	private int l;

	public int getWinterTemp(int l, int u)
	{
		return super.setReading( l, u );
	}

	public int getSpringTemp(int l, int u)
	{
		return super.setReading( l, u );
	}

	public int getSummerTemp(int l, int u)
	{
		return super.setReading( l, u );
	}

	public int getFallTemp(int l, int u)
	{
		return super.setReading( l, u );
	}

}

HumiditySensor class code:

public class HumiditySensor extends Sensor{

	private int u;
	private int l; 

	public int getHumidity()
	{
		return super.setReading();
	}

	public int getLowHumidity(int u)
	{
		return super.setReading( u );
	}

	public int getHighHumidity(int l, int u)
	{
		return super.setReading( l, u );
	}
}
