HOMEWORK # 4 QUESTION # 1. Write a Java program that contains a method named DisplayStock. The input argument to this method is the number of days and the share points on the first day. The method is used to decrease and increase the share points in the same way as in Problem 1 of Homework #3. The method then displays a table showing the days and the share points on those days (as shown below). The method doesnt return anything.

The main method in the program will first ask the users to enter the number of days in the specified period and the share points on the first day (in the same way as Problem 1 in Homework #3. The program should then call the DisplayStock method that outputs the table (as shown below).

For example, if a user enters as below:

Number of days in the period: 11 Share points on the first day: 550

The program (using the DisplayStock method) outputs the following:

Day Share Points

1 550

2 600

3 650

4 700 5 750

6 800

7 775

8 750

9 725

10 700

11 675

(HOMEWORK # 3 PROBLEM # 1 REFERENCED IN THIS QUESTION)

Assume that the share points of a company fluctuate with a particular pattern in the New York Stock Exchange. It increases by 50 points every day in the first half of a given period and decreases by 25 points in the second half. If the number of days in a given period is odd, the first half is considered a day more than the second half.

Write a Java program that will first ask users to enter the number of days in a given period and the share points on the first day. The number of days that is entered must not be less than 10 and more than 20. If it is not so, the user must be prompted to enter the input again with the following message: The number of days doesnt meet the required criteria, enter it again. The program should output a table showing the days and the share points on those days.

For example, if a user enters as below:

Number of days in the period: 11 Share points on the first day: 550

The program should output the following:

Day Share Points

1 550

2 600

3 650

4 700

5 750

6 800

7 775

8 750

9 725

10 700
