Hands-On Assignments Part II
Assignment 1-5: Querying the DoGood Donor Database
Review the DoGood Donor data by writing and running SQL statements to perform the following
tasks:
1. List each donor who has made a pledge and indicated a single lump sum payment. Include
first name, last name, pledge date, and pledge amount.
2. List each donor who has made a pledge and indicated monthly payments over one year.
Include first name, last name, pledge date, and pledge amount. Also, display the monthly
payment amount. (Equal monthly payments are made for all pledges paid in monthly
payments.)
3. Display an unduplicated list of projects (ID and name) that have pledges committed. Don't
display all projects defined; list only those that have pledges assigned.
4. Display the number of pledges made by each donor. Include the donor ID, first name, last
name, and number of pledges.
5. Display all pledges made before March 8, 2012. Include all column data from the
DD PLEDGE table.
Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods.
Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing.
Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons.
Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
