Lab Description:

This is a program that will allow the user to enter numbers to compute several statistics using Classess and overloaded methods. In the class it have one setter method to accept new number and a getter to receive. When the user exit the program it will display the following

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

Code

// main method lab 2
// calls other method to compute several statistics
import java.util.Scanner; //program uses Scanner

public class NumberStatsClass{

   public static void main(String [] args){
      //create a Scanner to obtain input from user
      Scanner input = new Scanner(System.in);

      NumberStats MyNewValue = new NumberStats();  //Create newValue objective

        float num2;
        boolean end = true;
        MyNewValue.welcome();
        num2 = input.nextInt();

        if(num2 == 1){

      while( end ){

         { System.out.print("Please enter you number: To end program enter 'n' ");
