I need to update this program to follow the these requirements please and thank you :

Do not use packages

Every class but the main routine class must have a toString method . The toString method for Quadrilateral should display its fields: 4 Points.

All instance variables should be declared explicitly private .

Area incorrect : enter points no: 1 1 3 enter points no: 2 6 3 enter points no: 3 0 0 enter points no: 4 5 0 This is a Parallelogram Area is : 15.811

Type of quadrilateral incorrect : enter points no: 1 5 4 enter points no: 2 5 0 enter points no: 3 0 4 enter points no: 4 0 0 This is a Parallelogram Area is : 20.000

The assignment question is :

Write an inheritance hierarchy for the classes Quadrilateral (an abstract class), Trapezoid, Parallelogram, Rectangle, and Square and then code it up. Create and use a Point class that has instance variables: x-coordinate and y-coordinate (each quadrilateral will have 4 of these, declared in the Quadrilateral class as protected). Each class must be defined in a separate .java file.Write one or more constructors, get and set methods for each class, and another method that computes the area of the object of each class (except for Point and Quadrilateral). For simplicity require that one side of any CMPSC Assignments4quadrilateral lie along the x-axis, and any figure with parallel sides will have a parallel side lying along the x-axis; do NOT assume that the points have to entered in any particular order; reject any input that fails to meet these conditions. Test all of these methods.In a separate class write a main function that prompts the user for the 4 points. Hence there will be 7 classes: Point, Quadrilateral (abstract), Trapezoid, Parallelogram, Rectangle, Square, and a Driver (with the main routine).Extra credit: enhance the above to remove the simplifying requirement (NOT trivial!).

QUESTION 1 BUSINESS CASE: THIS IS BUSINESS In recent years, because of the Public Procurement Act, District Assemblies have been given the authority to award contracts on certain projects, which do not cost more than 150 million cedis. In view of this, at the District where I work, the Assembly was to construct three markets, at 150 million cedis per project. However, the law is that before such contracts are awarded, they should be made known to the general public by advertising in any of the local newspapers. Therefore, these three market projects were subsequently put on tender through publication in one of the Ghanaian daily newspapers. One week after the advertisement, I received an Expedited Mail Service (EMS) letter, inviting me to Accra to meet a man I did not know for an important message at a particular date. Initially I did not want to honour the invitation. However, upon reflection I decided to go and meet the man because I was expecting some important information from a brother who was in the United States. On arriving in Accra, specifically at the man’s office in the Kantamanto commercial area, I was told the man was attending a meeting at a nearby office building and had directed that I should wait for him. I met the man’s secretary at the office. He served me a bottle of malta guinness. About twenty minutes later, the man arrived from the meeting and I was introduced to him. Beaming with smiles, he in turn introduced himself by mentioning his name as Mr. Opoku Afriyie. As it was already lunchtime, he suggested that we go to a restaurant for lunch. We found ourselves in a popular restaurant. I was asked to order whatever I wished to eat. But, as I did not know why I was being entertained, I was not at ease. The man kept saying, “Oh feel free, you are at home”. There was no doubt that he wanted to impress me. We, finally, drove back to his office. It was then he introduced himself to me as a building contractor and explained why he had invited me to Accra. He told me that he had read the advertisement from my Assembly inviting contractors to bid for the construction of the three markets. He was interested, he continued. He went on to say that, at a meeting somewhere, a friend told him to contact me because I was the schedule officer for those projects, he would be grateful and he was prepared to offer something. He ended by saying: “My brother, this is business that we are talking of. Here is ¢10,000.00 and 2 packets of roofing sheets. I want you to tell me the bill of quantities and estimated quotations from your consultants, and also quotations from other bidders”. In fact, I was flabbergasted and surprised to hear that. For five minutes, I was quiet and the man was doing all the talking. First, I needed six hundred cedis to pay my younger sister’s school fees. Second, I needed about one packet of aluminum roofing sheets to renovate my parents’ building. However, because it was difficult to say no to him and at the same time, I did not want to accept the offer, I politely suggested to the man to submit his completed contract document, telling him that his chances of winning were high, as at the time nobody had come for any of the contract forms. He was persistent and was prepared to offer an additional ¢500.00. But I refused to take anything from him. I then asked to leave; he asked his driver to take me to the State Transport Yard to take a bus back. He gave me ¢500.00 to pay for my transport fare, which I took.

vii. What do you understand by the term ethical dilemma?

viii. Besides this case, mention three other ethical issues that public officials encounter in their daily work life

ix. Mention four (4) importance of values to you as an individual or the District Assembly you work with.

x. Discuss the Blanchard and Pearl’s model of resolving ethical dilemmas

A firm in the year 1990 bought 60 baseball bats for $20 each and sold 40 of them in the same year for $ 25 each. What was the firm’s profit or loss for the year?

Q5:

1. The cost of a baseball bat to a trading company is $ 28. What should its selling price be if it wishes to earn 25% as a percentage of cost.
2. The cost of a baseball bat to a trading company is $ 28. What should its selling price be if it wishes to earn 25% as a percentage of sales.

Your firm has a free cash flow of $300 at year 1, $360 at year 2, and $864 at year 3. After three years, the firm will cease to exist. As of today (i.e. at year 0), the firm is partially financed with a 1-year maturity debt, whose face value is $660 and interest rate is 10%. After the debt matures at year 1, the firm will not issue any more debt and will remain unlevered. Assume that the firm’s unlevered cost of capital is 20%, and the firm’s cost of debt is identical to the interest rate on the debt (i.e. 10%). The corporate tax rate is 40%.

What is the firm’s enterprise value if the firm were unleveled?

1. What is the discount rate for the interest tax shield?

   	A.	Cost of levered equity
   	B.	WACC
   	C.	Cost of debt
   	D.	Cost of unlevered equity

1. What is the present value of the interest tax shield?

   	A.	$12
   	B.	$33
   	C.	$24
   	D.	$66

1. What is the firm’s enterprise value?

   	A.	$1,000
   	B.	$1,524
   	C.	$1,024
   	D.	$1,012

A bank invested $50 million in a one-year asset paying 10 percent interest per year and simultaneously issued a $50 million, two-year liability paying 8 percent interest per year to pay for it. • Is the bank short funded or long funded? • What is the bank’s net interest income in year one • What will be the bank’s net interest income in year two if at the end of the first year all interest rates have decreased by 1.5 percent (150 basis points)?
