Lab 3

Lab Description:
Lab 3 is basically a lab 2 recreation but with some modification using inheritance. First of all we need to create a class call Sensor which contain an int field reading and 2 kind of methods which is setReading and getReading. After that we are require to create 2 other classes call TemperatureSensor and HumiditySesor. In TemperatureSensor, we need to implement the getWinterTemp, getSpringTemp, getSummerTemp, and getFallTemp methods by calling the super class methods appropriately. On the other hand, we need to implement getHumidity, getLowHumidity, and getHighHumidity in the HumiditySensor class. Lastly we need to create the SensorsStatsApp class that do all the calculation and display a menu to ask the user what simulation they want to use and after the simulation, the application should display the results for the user.

Code:
Sensor:

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:

public class TemperatureSensor extends Sensor{

	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:

public class HumiditySensor extends Sensor{

	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 );
	}
}
