Lab Description:
In this lab further knowledge of Java such as getter and setter methods and object instantiation will be applied to the previous lab to write an easier code to read. Methods are used in this case since a class’s private attributes can only be manipulated by methods and object instantiation is used to create classes for each object.

Code:

import java.util.Scanner;

public class Lab3 {

	public static void main (String [] args)

	{

		NumberStats myNumberStats = new NumberStats();

		Scanner input = new Scanner( System.in);

		int number;
		do{

			System.out.println ("Enter a series of numbers.");

			System.out.println ("Enter 0 when finshed entering numbers.");

			number = input.nextInt();

			myNumberStats.setNewNumber(number);
		}while (number != 0);
		//do while

		//display menu
		System.out.println(myNumberStats.getFirstNumber());

		System.out.println(myNumberStats.getlastNumber());

		System.out.println(myNumberStats.getcount());

		System.out.println(myNumberStats.getmaximum());

		System.out.println(myNumberStats.getminimum());

		System.out.println(myNumberStats.getsum());

		System.out.println(myNumberStats.getaverage());
		//Call all the get methods and display them
	}
	public static int total(int number, int sum)

	{

		int totalsum = number + sum;

		return totalsum;

	}
