Request for Proposal

Develop a Java application that plays a “guess the number” game as described below.
a) Your application first gets a random number in the range 1-1000 inclusive (you might want to use Math.random() or the Random class).
b) The application then displays the following prompt (probably via a JLabel):
I have a number between 1 and 1000. Can you guess my number?
Please enter your first guess.
Post a textbox for the user to enter a number and post a message telling the user to hit ‘Enter’ after entering a guess in a textbox (probably using a JTextField).
c) Input the user’s guess in the code for a previously-registered event-handler method (consider using the event-handling approach discussed in the text, or the actionPerformed() method of class based on the ActionListener interface, which will require some additional research outside the text).
d) For the first guess, color the entire background red, meaning that they are getting warmer (you might want to use the setBackground() method for a container). If this is the second or later guess, and they are further from the correct number than the last guess, then color the entire background blue. If they get the correct number then color the background some other color than red or blue.
e) If the user guessed the number correctly, respond with their number, post a congratulatory message, get a new random number, and display a JButton to start a new game. Otherwise, to help the user close in on the correct number, post a message, with their guessed number, whether they are “TOO HIGH” or “TOO LOW” from the correct number, and whether they are “WARMER” or “COLDER” (this should match the background color). Also report the guess number of the next guess (e.g. “Enter guess number nnn”). You might want to use a concatenated string in JLabel for these incorrect guess messages.
f) The process is repeated each game until the user guesses the correct number. Be sure that you erase obsolete status messages.

• BestBuy.com

Answer the following questions:

Identify the study method used and why it was appropriate

Explore some of the qualitative or quantitative methods gathered.                                               

 Answer these two additional questions:

• How would you conduct the study any differently?
• Given the nature in the advance of technology, how do you foresee technology changing the way studies such as these are conducted in the future?

 Exp19_Excel_Ch05_HOEAssessment_Fine_Art

Start Excel. Download and open the file named Exp19_Excel_Ch05_HOEAssessment_FineArt.xlsx. Grader has   automatically added your last name to the beginning of the filename.

Before using the Subtotal command, the data must be sorted by   categories.
 

  On the Subtotals worksheet, perform a three-level sort by Status, then by   Type, and finally by Title, all in alphabetical order.

You want to subtotal data to identify the highest issue prices,   estimated values, and percentage change by the Status category and the Type   of art work.
 

  Use the Subtotals feature to insert subtotal rows by Status to identify the   highest (max) Issue Price, Est. Value,   and Change. Then add a second-level subtotal by Type using the same function   and columns.

You want to apply an outline so that you can collapse values used for   the formula in column F. Then you will collapse the subtotaled rows.
 

  Apply an auto outline and click the collapse button above column F. Collapse   the data by displaying only the subtotals and grand total rows. Set a print   area for the range B1:F48.

A PivotTable can give additional perspective to data. You will use   the Art worksheet to create a recommended PivotTable.
 

  Use the Art worksheet to create the recommended PivotTable called Sum of   Issue Price by Type on a new worksheet named Sold   Out. Mac users create a PivotChart that includes   the Status field in the Filters area, the Est. Values field in the Columns   area, the Type field in the Rows area, and the Issue Price field in the Values   area.
 

  Name the PivotTable Art Type.

Currently, the PivotTable contains the Issue Price field. You will   add the Est. Value field to compare the difference between total value of the   art based on issue price and estimated value today.
 

  Add the Est. Value field below the Sum of Issue Price in the Values area.

You want to display the average   values instead of the sum of the values in each category.
 

  Modify the two Values fields to determine the average Issue Price and average   Est. Value by type. Change the custom name to Average Issue Price and Average Est. Value, respectively.

Format the two Values fields   with Accounting number type with zero decimal places.

The Summary sheet is designed to   display two key averages from the PivotTable on the Summary sheet.
 

  Display the Summary sheet. In cell B2, insert the GETPIVOTDATA function that   references cell C4 on the PivotTable in the Sold Out sheet. In cell B3,   insert the GETPIVOTDATA function that references cell C9 on the PivotTable in   the Sold Out sheet.

Some art is still available, but   most art is sold out. You want to create a filter to focus on the sold-out   art.
 

  Display the Sold Out sheet. Add the Status field from the field list to the   Filters area. Set a filter to display only art that is Sold Out.

Insert a slicer for the Type   field, change the slicer height to 2 inches, change the button width to 2 inches, and apply the Light   Blue, Slicer Style Dark 5. Cut the slicer and paste it in cell A11.
 

  Note, depending upon the Office version used, the style name may be Slicer   Style Dark 1.

Display the Totals sheet. Insert   a calculated field named Field1 to determine difference between the two   values, Est. Value   and   Issue Price.   Change the custom name to Value Increase.

With the PivotTable on the   Totals sheet displayed, change the Sum of Issue Price and Sum of Est. Value   fields to show values as percentage of column totals.

With the PivotTable on the   Totals sheet displayed, select Light Blue, Pivot Style Medium 6 and display   banded rows.

Display the Porcelains sheet.   Create a relationship between the PORCELAINS table using the Code field and the   CODES table using the Code field.

Create a blank PivotTable from   inside the PORCELAINS table. Add this data to the Data Model. Name the   worksheet Porcelain Pivot and name the PivotTable Porcelain   Values.

Display all tables in the   PivotTable Fields List task pane. Add the Description from the CODES table to   the Rows area and the Issue and Est. Value fields as Values from the   PORCELAIN table. Format the two value fields with Accounting number format   with zero decimal places.

Create a clustered column   PivotChart from the Porcelain Values PivotTable. Cut the PivotChart and paste   it in cell A7.

Add a chart title and type Porcelain   Values. Bold   the title. Change the value axis maximum bounds to $3,000.

Change the PivotChart height to 2.5 inches and the width to 3.7 inches.

Create a footer on all   worksheets (except Art) with your name in the left section, the sheet name   code in the center section, and the file name code in the right section.

Ensure that the worksheets are   correctly named and placed in the following order in the workbook: Subtotals,   Totals, Sold Out, Art, Summary, Porcelain Pivot, Porcelains.
