Lab 2

Lab Description:
The idea of Lab 2 basically is to re-create Lab 1 with separating it into 2 classes which is TemperatureSensor and TemperatureSensorStats. In the TemperatureSensor class, we need to implement four kinds of methods which include getWinterTemp that simulate temperature between 20-40, getSpringTemp that simulate temperature between 40-70, getSummerTemp that simulate temperature between 70-90, and getFallTemp that simulate temperature between 40-60. On the other hand, the other class TemperatureSensorStats will consist of a main menu that have 5 options of the season with and exit. Whenever the user asked to do simulation on this class, the class should call the corresponding method from the TemperatureSensor class we created separately. Other than that, the program still keep track of all the statistics which include first temperature, last temperature, lowest temperature, highest temperature, total sum of all temperature and average temperature generated in each season just like in Lab 1.

Code:
TemperatureSensor Code:

public class TemperatureSensor {
	
	int maxValue = 0;  // Will hold Max Value Generated by Sensor
	int minValue = 0;  // Will hold Min Value Generated by Sensor
	int sumValue = 0;  // Will hold Sum of Values Generated by Sensor
	int avgValue = 0;  // Will hold Average of Values Generated by Sensor
	
	/* getWinter Temp code below. Code is basically a repetition in all the get methods*/
	public int getWinterTemp(int counter)
	{
		int temp[] = new int[counter];	// New Array initialized for required number of values
		int rand;						// Variable used to hold random generated value
		for(int i = 0; i<counter; i++)	// For loop used to generate required number of values
		{
			rand = 20 + (int)(Math.random() * ((40 - 20) + 1));
