Lab Description:

This is a program that will allow the user to enter numbers to compute several statistics. First, it show a menu that will ask the user to (1) enter a number or (2) exit. They can enter as many number as they wished  positive or negatives. When the user is finish entering the number it will show:

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

Code:

import java.util.Scanner;
public class number {
//David Chen
//CET3640 LAB 1

public static void main(String[] args){

Scanner input = new Scanner( System.in );

int InputNumber =0, a, count = 0;
double firstnum = 0,lastnum = 0, min = 0, max = 0, avg = 0,sum = 0, max2 = 0, min2 = 0;

   System.out.println("Press 1 to enter number");
   System.out.println("Press 2 to exit the program");

   a = input.nextInt();

if(a == 1){

while (a ==1 ){
   System.out.print("Enter A Number,to exit press Ctrl + Z: ");
   InputNumber = input.nextInt();
   sum += InputNumber;
