Question Answered step-by-step the class file — public class SalesData { private double[] sales;…   the class file — public class SalesData{   private double[] sales;    public SalesData(double[] s)   {           sales = new double[s.length];                  for (int index = 0; index < s.length; index++)         sales[index] = s[index];    }  public double getTotal()   {      double total = 0.0;                 for (int index = 0; index < sales.length; index++)         total += sales[index];                        return total;     }  public double getAverage()   {      return getTotal() / sales.length;   }  public double getHighest()   {      double highest = sales[0];      for (int index = 1; index < sales.length; index++)      {         if (sales[index] > highest)            highest = sales[index];      }      return highest;   }   public double getLowest()   {      double lowest = sales[0];      for (int index = 1; index < sales.length; index++)      {         if (sales[index] < lowest)            lowest = sales[index];      }      return lowest;   }}question,  creat e  a program to demonstrate the use of the class.  The program should begin with a passcode validation that will only allow the user to access the program if a passcode with at least 2 uppercase letters and at least 2 lowercase letters is entered.  If an inaccurate passcode is entered, the program should loop and prompt the user again until a proper code is entered.  (25 Points)  5.       Given the SalesData class file, complete the demo program for weekly sales that accepts sales figures for 5 days from the user into an array.  Then, creat e an instance of the class and pass the array.  Finally, return figures for output that should create an output similar to this:  (75 Points)using this class file, output should be likeEnter a Password:mei,ejThe password did not meet the requirements of at least 2 uppercase letters and at least 3 lowercase lettersPlease reenter the password:Enter a Password:uhduIWEIIEnter the sales for day 1100Enter the sales for day 2200Enter the sales for day 3300Enter the sales for day 4400Enter the sales for day 5500The total sales were $1,500.00The average sales were $300.00The highest sales were $500.00The lowest sales were $100.00  Computer Science Engineering & Technology Java Programming CS 160 Share QuestionEmailCopy link Comments (0)
