Write a Java program that reads a student\'s name together with his or her test

Question

Write a Java program that reads a student's name together with his or her test scores. The program should then compute the average test score for each student and assign the appropriate grade. The grade scale is as follows: 90-100,A; 80-89,B; 70-79,C; 60-69,D; 0-59,F;.

Your program must use the following methods:
a: A value-returning method, calculateAverage, to determine and return the average of five test scores for each student. Use a loop to read and sum the five test scores.(The method does not output the average test score. That task must be done in the method main.)

b: A value-returning method, calculateGrade, to determine and return each student's grade. (This method does not output the grade. That task must be done in the method main.)

Test your Java program on the following data. Read the data from a file and send the output to a file. Do not use any global variables. Use the appropriate parameters to pass values in and out of methods.

Given names and grades to use is:
Johnson 85 83 77 91 76
Aniston 80 90 95 93 48
Cooper 78 81 11 90 73
Gupta 92 83 30 69 87
Blair 23 45 96 38 59
Clark 60 85 45 39 67
Kennedy 77 31 52 74 83
Bronson 93 94 89 77 97
Sunny 79 85 28 93 82
Smith 85 72 49 75 63
