Task 2

Write a method called attendance that reads a file containing student attendance and returns the number of points each student earns for attendance and their grades for attendance.

Create a file called attendance.txt that contains the following text:

yynyyynnynyynyyynynnyyynynnyynyynnnyyynnynynn nyynnyyyynynnnyyynnnyyynnnnnynynynynynyynynyn yynynynyynyynyynnyyynyynnnynynnynnyynyynynyny

A call to attendance() should produce the following output:

Section 1

Student points: [30, 25, 25, 20, 15]

Student grades: [100.0, 83.3, 83.3, 66.7, 50.0]

Section 2

Student points: [25, 30, 20, 20, 15]

Student grades: [83.3, 100.0, 66.7, 66.7, 50.0]

Section 3

Student points: [25, 25, 25, 30, 20]

Student grades: [83.3, 83.3, 83.3, 100.0, 66.7]

Rules:

Students earn 5 points for reach section attended, up to 30

Each line represents a section

A line consists of 9 weeks worth of data

Each week has 5 characters, because there are 5 students

Within each week, each character represents one student

n means the student was absent (+0 points)

y means they attended and did the problems (+5 points)

Your solution should consist of three methods:

countPoints(String line) : returns an array with then containing the attendance record for each student converted into a point total (out of 30)

computeGrades(int[] points) : returns an array containing the grade for each student based on the points they earned in attendance divided by the total points possible (rounded to one decimal point)

results(int section, int[] points, double[] grades) : prints the grades for the students as shown above.
