Lab 1 procedures:

Create a program that will prompt the user to enter numbers to compute several statistics. First, display a menu that will ask the user to (1) enter a number or (2) exit. The user should be able to enter as many numbers as wished (positives or negatives). When the user finishes the following statistics should be displayed:

1. First number entered
2. Last number entered
3. Count of number entered
4. Lowest two numbers
5. Highest two numbers
6. Total Sum
7. Average

Overview:

In this lab I was able to complete the tasked asked from the user with a simple number of loops. In addition, I added a way for the program to exit if an invalid option is enters.

Code:

package Lab1;

import java.util.*;

public class Lab1 {

	public static void main(String[] args) {
		int count = 0, firstNum = 0, lastNum = 0, lowNum = 32767,  hiNum = 0, sum = 0, avg = 0, choice = 1;
		int lowNum2 = lowNum;
		int hiNum2 = hiNum;

		while (choice == 1)
		{		
			@SuppressWarnings("resource")
			Scanner keyboard = new Scanner(System.in);
			System.out.println("What would you like to do: \n1) add a number \n2) exit " );
			choice = keyboard.nextInt();
			if(choice > 2 || choice < 1) 			{ 				System.out.println("Incorrect input system will exit!"); 			} 			if(choice == 2) 			{ 				System.out.println("Thank you have a nice day!"); 			} 			if(choice == 1) 			{ 				System.out.println("Please enter a number"); 				int input = keyboard.nextInt(); 			 				if(count == 0) 				{ 					firstNum = input; 				} 			 				lastNum = input; 			 				if(lowNum > input)
				{
					lowNum = input;
				}
				if(lowNum < lowNum2)
				{
					lowNum2 = lowNum;
				}
				if(hiNum < input)
				{
					hiNum2 = hiNum;
					hiNum = input;
				}

				sum = sum + input;
				count++;
				avg = sum/count;

			}	
		}		System.out.println("The first number = " + firstNum);
				System.out.println("The last number = " + lastNum);
				System.out.println("The first lowest number = " + lowNum);
				System.out.println("The second lowest number = " + lowNum2);
				System.out.println("The first highest number = " + hiNum);
				System.out.println("The second highest number = " + hiNum2);
				System.out.println("The total sum = " + sum);
				System.out.println("The avrage of all numbers = " + avg);
	}
}
