Help Please Write a program called StudentAverageTestScoreja

Help Please!!

Write a program called StudentAverageTestScore.java. Five students have taken five tests. The program should ask the user to enter each student\'s name and his or her five test scores. The five student names should be stored in an array, and the five test scores for each student should also be stored in an array. Use nested loops, in which the outer loop handles the student names, and the inner loop handles the current student\'s test scores. This program should have methods that return a specific student\'s name, average test score, and a letter grade based on the average. Write the following methods in the program. Print a project description that tells the user what to do. calAvg- This method should accept five test scores as an argument and return the average of the test scores. letterGrade - This method should accept test scores as an argument and return a letter grade for the test scores, based on the following grading scale. getName - This method should accept student names as an argument and return a student\'s name. Score Letter Grade 90-100 A 80-89 B 70-79 C 60-69 D Below 60 F The program should display each student\'s average test score (formatted to one decimal place) and letter grade. **lnput validation: Do not accept test scores less than zero or greater than 100. *Note: Comment your program Use meaningful prompts Provide clear instructions to the user
