I have several issues that I cannot figure out. I need to figure out how to ensure that all data is saved in the database. I also need to figure out how to display an order summary and order list. Any pointers in the right directions are appreciated.

My program this week is to create an application that will calculate services (oil change, car wash, or both) provided to customers. The services should be totaled and a message box should display the services rendered and the total sales amount for the purchase. Also, the client should be able to clear the application for a new user. For whatever reason, this inner class is confusing me, and I'm not sure that I'm even on the right track. Any help would be greatly appreciated.

I really appreciate your help... Apparently, I'm EXTREMELY dumb with this. So you mean... That I have:

System.out.print("Enter class credits: ");
String credits = input.nextLine();

And I need to change it to:

System.out.print("Enter class credits: ");
double credits = input.nextDouble();

Where would I put the:

info.addClass(credits, grade);

When I added it after the grade code, it messed up my prompts.

I guess I don't understand what I am supposed to do to call them...

I cannot figure out what I am doing wrong. I just don't feel like I'm ever going to understand all of this. My prompts and loop are working fine. However, I am not getting any output. I'm sure it's a fairly simple thing, but I just don't see it so I can't know for sure what I need to fix. I have watched all the videos and looked through my textbook and the internet, but I need someone to "dumb" it down for me, I guess. Thank you, in advance, for your patience and help.

I am still working on this myself, but I am kind of just needing a little reassurance that I am on the right track or a push in the right direction. This is all really new to me, and I'm honestly getting a little overwhelmed. Thank you! You must create a sales tracking program named SalesTracking.java. This program will use arrays to store and process monthly sales as well as compute average yearly sales, total sales for the year, and which month had the highest sales and which month had the lowest sales. You should use parallel arrays. Your first array (monthArray) should be initialized with all of the months. This array should have 12 locations of course. Your other array should be named monthlySales. Like your monthArray, this array should be 12 locations that store the amount of sales for each month. The program should prompt the user for the sales for each month starting with January. The arrays (monthlySales and monthArray) should be created in main and passed to the methods as needed. Your program should have methods that do the following. getSales(monthArray, monthlySales): This method receives the monthArray and monthlySales arrays as arguments. It prompts the users for the sale for each month. This amount should be stored and returned into the corresponding location in the monthlySales array. For example, January sales should be stored in the first location, February sales should be stored in the second location, and so forth. computeTotalSales(monthlySales): This method receives the monthly sales array as an argument and returns the total sales of the year. computeAverageSales(monthlySales): This method receives the monthly sales array as an argument and returns the average sales for the year. computeHighestMonth(monthlySales): This method receives the monthly sales array as an argument. This method will search and compare the values of the monthly sales array for the highest value. The method will return the index(or location in the array) of the month with the highest value. computeLowestMonth(monthlySales): This method receives the monthly sales array as an argument. This method will search and compare the values of the monthly sales array for the lowest value. The method will return the index (or location in the array) of the month with the lowest value. displaySaleInfo(totalSales, averageSales, highestMonth, highestSales, lowestMonth, lowestSales): This method will receive the total yearly sales, average monthly sale, the month with the highest sales, as well as the s

I am having trouble figuring out how to write the following problem... "Many organizations use percentage of markup (e.g., profit margin) when analyzing financial data. To determine the percentage of markup for a particular item, simply subtract the cost for the item from the retail price to obtain the dollar amount of profit, and then divide the profit by the cost of the item. The resulting solution is then multiplied by 100 to determine the percent of markup. Using a SELECT statement, display the title of each book and its percent of markup. For the column displaying the percent of markup, use “Markup %” as the column heading."

Can anyone tell me what I am doing wrong? I am getting an error message on line 9 (Locid)...

Can someone please guide me through this?

In this program you will create a Windows Form application that will calculate and display the money made by a drive-in movie theater each night. The movie theater has two types of nights. A “Regular” night is where each person in a guest car has to buy a ticket, and each ticket costs $10. A “Car” night is a special promotion where there is one price per car of $15, no matter how many guests are in the car.

In addition to the cost of entry (either Regular or Car), the theater sells popcorn and candy but the price of the items depends on the type of night. On a Regular night popcorn costs $1.50 per box and on a special Car night popcorn costs $2.00 per box. On a Regular night candy cost $2.25 per candy box, while on a special Car night candy cost $3.00 per box.

On any night, the maximum number of cars allowed in is 500 and the maximum number of individual tickets is 3,000; the theater can produce 4,500 bags of popcorn each night and has 4,000 candy items.

Once the total sales are calculated, the program will display a summary message with the type of night, the total number of cars, the total ticket sales, the total popcorn sales, the total candy sales, and the total sales amount.

Excuse me. I don't understand. I'm just learning this all, and it's very confusing. :(

I am trying really hard, but I'm just not getting this... This is what I need to do...

Dim prompt, sideLength As String Dim area, length As Double prompt = InputBox("Enter sides of the square.") sideLength = Convert.ToDouble(length) area = length * length Me.lblOutput.Text = "Square of side length " & length & ": " & area

Oh, my goodness! I fixed the problem, and now everything works! Thank you!

This is what I have so far, but I can't get past putting in the number of units to use. I feel like I'm never going to get a hang of this coding stuff. :( Module Module1 Dim miles As Decimal = 0 Dim kilometers As Decimal = 0 Dim answer As String Sub Main() Console.WriteLine("Do you want to convert miles or kilometers?") answer = Console.ReadLine() If answer = "miles" Then Console.WriteLine("What is the number of miles?") Console.ReadLine() Call convertMilesToKilometers() Console.WriteLine("The converted value is: " & kilometers) ElseIf answer = "kilometers" Then Console.WriteLine("What is the number of kilometers?") Console.ReadLine() Call convertKilometersToMiles() Console.WriteLine("The converted value is: " & miles) End If Console.ReadLine() End Sub Function convertMilesToKilometers() As Decimal kilometers = miles / 0.62137 Return kilometers End Function Function convertKilometersToMiles() As Decimal miles = kilometers * 0.62137 Return miles End Function End Module

Assignment It’s often necessary to convert between units. In this exercise, you will create two functions for converting between units of distance. The first function will be called ConvertMilesToKilometers(), which will accept one parameter for the number of miles. It will return the equivalent number of kilometers. The second function will be called ConvertKilometersToMiles() and will accept kilometers as its parameter; this will return the equivalent number of miles. The main method will ask the user if he or she wants to convert miles to kilometers or kilometers to miles. It will then ask for the number of miles or kilometers. It will call the appropriate method and display the converted value. To convert miles to kilometers, divide miles by 0.62137. To convert kilometers to miles, multiply kilometers by 0.62137. Example Do you want to convert to Miles or Kilometers? (M or K): K Enter number of Kilometers: 3.5 3.5 kilometers equals 2.174795 miles.
