Java Programming

Task #1 Extending the BankAccount Class

1. Copy the files AccountDriver.java (Code Listing 10.1) and BankAccount.java(Code Listing 10.2) from the Student CD or as directed by your instructor.BankAccount.java is complete and will not need to be modified.

2. Create a new class called CheckingAccount that extends BankAccount.

3. It should contain a static constant FEE that represents the cost of clearing one

   check. Set it equal to 15 cents.

4. Write a constructor that takes a name and an initial amount as parameters. It

   should call the constructor for the superclass. It should initializeaccountNumber to be the current value in accountNumber concatenated with –10 (All checking accounts at this bank are identified by the extension –10). There can be only one checking account for each account number. Remember since accountNumber is a private member in BankAccount, it must be changed through a mutator method.

5. Write a new instance method, withdraw, that overrides the withdraw method in the superclass. This method should take the amount to withdraw, add to it the fee for check clearing, and call the withdraw method from the superclass. Remember that to override the method, it must have the same method heading. Notice that the withdraw method from the superclass returns true or falsedepending if it was able to complete the withdrawal or not. The method that overrides it must also return the same true or false that was returned from the call to the withdraw method from the superclass.

6. Compile and debug this class.

Task #2 Creating a Second Subclass

1. Create a new class called SavingsAccount that extends BankAccount.

2. It should contain an instance variable called rate that represents the annual

   interest rate. Set it equal to 2.5%.

3. It should also have an instance variable called savingsNumber, initialized to 0.

   In this bank, you have one account number, but can have several savings accounts with that same number. Each individual savings account is identified by the number following a dash. For example, 100001-0 is the first savings account you open, 100001-1 would be another savings account that is still part of your same account. This is so that you can keep some funds separate from the others, like a Christmas club account.

4. An instance variable called accountNumber, that will hide theaccountNumber from the superclass, should also be in this class.

5. Write a constructor that takes a name and an initial balance as parameters and calls the constructor for the superclass. It should initialize accountNumber to be the current value in the superclass accountNumber (the hidden instance variable) concatenated with a hyphen and then the savingsNumber.

Write a method called postInterest that has no parameters and returns no value. This method will calculate one month's worth of interest on the balance and deposit it into the account.

6. Write a method that overrides the getAccountNumber method in the superclass.

7. Write a copy constructor that creates another savings account for the same person. It should take the original savings account and an initial balance as parameters. It should call the copy constructor of the superclass, and assign thesavingsNumber to be one more than the savingsNumber of the original savings account. It should assign the accountNumber to be theaccountNumber of the superclass concatenated with the hyphen and thesavingsNumber of the new account.

8. Compile and debug this class.

9. Use the AccountDriver class to test out your classes. If you named and

   created your classes and methods correctly, it should not have any difficulties. If you have errors, do not edit the AccountDriver class. You must make your classes work with this program.

10. Running the program should give the following output:

Account Number 100001-10 belonging to Benjamin Franklin
Initial balance = $1000.00
After deposit of $500.00, balance = $1500.00
After withdrawal of $1000.00, balance = $499.85

Account Number 100002-0 belonging to William Shakespeare
Initial balance = $400.00
After deposit of $500.00, balance = $900.00
Insufficient funds to withdraw $1000.00, balance = $900.00
After monthly interest has been posted, balance = $901.88

Account Number 100002-1 belonging to William Shakespeare
Initial balance = $5.00
After deposit of $500.00, balance = $505.00
Insufficient funds to withdraw $1000.00, balance = $505.00

Account Number 100003-10 belonging to Isaac Newton

Consider He, CaS, CH4, LiF, CaO, diamond, H2O, CH3CH2OH, LiCl, and CH3OCH3. Arranged

in increasing melting point, these are:

You have a daily demand for business cards of 5 units, and you are ordering your business cards from Business Card Kings, who charges $2 per card and $55 per order. For the calculation of your holding cost you think that an annual interest rate of 30% is reasonable. Suppose that you will use EOQ model. Note: Throughout this problem, you are required to round all solutions (intermediary results and the final answers) to integers.

1. Calculate the economic order quantity (i.e., EOQ) per order.

Now suppose that Business Card Kings provides a quantity discount: if you order less than 400 (including 400), it is $2 per card; but if you order more than 400, it is $1.25 per card.

2. Given this quantity discount scheme, calculate the optimal order quantity and the minimal cost (including holding, setup, and purchase costs).

Now suppose that the order delivery lead-time from Business Card Kings is two weeks.

3. Determine the re-order point based on the on-hand level of inventory of your business cards.

QUESTION 1 CASE

The coronavirus pandemic is a human tragedy, affecting hundreds of thousands of people globally. It is also having a growing impact on the global value chain, hence the global economy. All serious companies around the world have therefore found innovative ways of keeping business going nonetheless. One of such notable companies is Ghana’s Kantanka Inc. The company has established a dedicated team to ensure a simple but well- managed set of processes that maximize the health and safety of colleagues and customers. This team is led by the CEO of the company. The focus of the team has been broken down into five distinct work streams:  Employee management and wellbeing  Financial stress-testing and contingency planning  Supply chain monitoring  Marketing and sales  Any other business Kantanka Inc. is a car manufacturing company originating from Ghana which produces low-end vehicles. The company’s competitive advantage stems from its unconventional but effective and energy efficient technology which is not found in most vehicles around the world. The dashboard and other interior parts of the vehicles are made from wood, and the vehicles are powered by car batteries and solar energy. Recently, they have added on aircrafts and mechanized farming technologies. The company is set to take the African market by storm. The company decided in 2015 to enter Nigeria and Germany. With the backing of the government of Ghana, negotiations with both countries succeeded as negotiators from Nigeria and Germany were in natural sync with the Ghanaian lobbyist contracted. Once the company has gone international, it was only natural that value chain activities of the company would have to be rationalized to deal with the expansion, as well as all forms of risk with respect to exchange rate fluctuations. Speaking of financials, in this coronavirus pandemic period, companies such as Kantanka Inc. that entered into future contracts and used currency options as hedging instruments would have less to worry about since excuses from business partners would almost be non-existent. Recently in 2017, a company from Sậo Tome and Principé, called PreZi contacted Kantanka Inc. to obtain permission to use its technology. As to whether to agree or not to the agreement is still under scrutiny by Kantanka’s international expansion team.

a) Discuss five (5) ways the two negotiators can get along in order for their cultural backgrounds not to affect the outcome of their bargaining process.

b) Explain three (3) financial risks Kantanka Inc would definitely encounter.

c) What five (5) benefits is Kantanka Inc likely to gain from entering the German market?

d) Explain five (5) problems Kantanka Inc’s international expansion team should anticipate before entering the German market.

e) Explain the contractual strategy that would best characterize the Kantanka-PreZi agreement once agreed to.

The Hyundai Blue-Will Plug-In hybrid is a compact 4-door, 4-seat sedan.It is a test bed of new ideas, including panoramic glass roof with solar
cells for recharging batteries, a thermal generator that converts hot exhaust gases into electricity, drive-by-wire steering, lithium polymer
batteries, and touch screen controls. Blue-Will promises an EV driving range up to 40 miles on a charge and an economy rating up to 100 mpg.
Helping to achieve those numbers is a direct injection 1.6 liter 152-hp four, a CVT and a 100 kw electric motor..

1. A Hyundai Blue-Will hybrid is capable of an acceleration of 4.3 m/s. It has a mass of 770 kilograms of steel, 180 kilograms of iron, 110 kilograms of plastics, 80 kilograms of aluminum, 60 kilograms of rubber, 20 kilograms of glass, and 8 kilograms of other materials. The driver has a mass of 85 kg. a Sketch the system of the Blue Will b.Sketch the system of the driver c. What is the force on the driver from the acceleration? d.Compare the force of the car on the driver to the driver’s weight, using a ratio. 2. The Hyundai Blue Will hybrid is driving at a velocity of 125 kph, and crashes into another car traveling at a velocity of 35 kph. Assuming the drivers are of comparable mass, and the car bumpers lock on impact: a. What is the final velocity of the cars? b. If the famous Blue Will crashes into a tree, instead, in 2.6 seconds, what is the impulse? c. What is the total force exerted by the tree in stopping the Blue Will? 3. The Famous Blue Will hybrid is being driven at a velocity of 75 kph when the driver sees a tree ahead. a. The driver locks his brakes, causing the car to skid. The coefficient of friction of rubber on dry concrete is 1.0 (static) and 0.7 (kinetic). How much force will the brakes apply to the car? What difference would it make if the driver pumped the brakes? b. After 1.0 second of braking, what will be the car’s velocity? c. How far in advance will the driver need to start braking to avoid the tree? 4. The Hyundai has about the same drag as a Camry (about 0.36) and air has a density of about 1.21 kg/m3. The cross section of the Hyundai is about 1.5 m × 1.5 m. Take the torque provided by the engine at speed as about 250 lbf. a. What is the force applied by air resistance at 75 kph? b. Would this help the driver avoid hitting the tree in the previous problem? Why or why not? c. What is the maximum velocity of the car? Is this answer reasonable? Why or why not?
