I have a project due next week, and I am not very familiar with Java... How do I read an existing file into an array?

 

ProjectMCIS 5103: Advanced Programming ConceptsInstructor: Dr. Justin L. RiceDue Date: 4/24/2017Create a Final Grade Calculator.(100 points)Requirements:I.The system shall ingest student_grades_input.txt (see next page). This comma delimited input text filecontains the names and grades of 30 students. Each student has grades for six assignments: 3Homework Assignments, 1 Midterm, 1 Project, and 1 Final.II.The system shall compute the final numerical grade for each student using the following:final_numerical_grade = 0.45*[(HW1+HW2+HW3)/3] + 0.25*Project + 0.30*[(Midterm+Final)/2]III.The system shall use the following to determine the final letter grade:Final Numerical GradeFinal Letter Grade90 - 100A80 - 89B70 - 79C60 - 69D0 - 59FIV.The system shall use a GUI to display the final letter grade for each student.Note, a scroll bar may beneeded to fit all the names and grades within the GUI. Please be sure to include screenshots that detailthe entire output. More than one screenshot may be required.V.At the bottom of the GUI, include the total number of A's, B's, C's, D's, and F's.Instructions:Develop a reportthatdescribes the system architecture,provides an overview of the source code,andaddresses each of the five requirements (above). Note,all responses should be contained in ONE WORD orPDF document. Other formats will not be accepted.Do your best! This assignment is worth 25% of your final grade!
