Transcribed Image Text:6. Design a Java class with a main method that does the following. You must include a meaningful
comment for main and each method
a. Main invokes a method readScores to read input from a file (name of your choice) that
contains the name of the bowlers (no more than 25) and their bowling scores (two scores
per bowler). The program stops reading values when it has reached the end of the file.
For example, the file might contain:
Bob 203 176
Jane 210 253
Jack 300 189
Eileen 220 298
• As the method reads the data, it stores the name into a String array and the average
of the two bowling scores into an array of double.
• The method returns the actual number of bowlers read in
b. Main then invokes a method computeOverallAvg to:
compute (a) the overall average score of all the bowlers combined, (b) the average
score and name of the bowler with the highest average score and (c) the average
score and name of the bowler with the lowest average scores.
print to the console (a) the overall average score, (b) the name and average score of
the bowler with the highest average score and (c) the name and average score of the
bowler with the lowest average score. Average scores should appear with two
decimal places.
• The method receives an array of double, an array of String and the number of
records read in by readScores
c. Main invokes a method doParallelSort where the primary sort is the average score in
descending order (highest to lowest) and the bowlers' names are synched with the averages
The method receives an array of String, an array of double and the number of
records read in by readScores
d. Main then prints to a file (name of your choice) the values of the sorted arrays - primary order
is average score (with two decimal places) in descending order with bowler name next to it. A
heading should appear above the scores and names which is aligned with the data. For
example,

259.00
Eileen
244.50
Jack
231.50
Jane

Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson.

Also, use a MakeSale() method two or three times with each object, and display the final contents of each object’s data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salesperson’s full name—the first and last names separated by a space.
