In this tutorial, I am going to show you how to design a gradebook with Java. You can find the complete code in this step by step tutorial.

The question that we are going to solve in this tutorial is as follows:

A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores:

Test Score Letter Grade
90–100 A
80–89 B
70–79 C
60–69 D
0–59 F

Write a class that uses a String array or an ArrayList object to hold the five students’ names, an array of five characters to hold the five students’ letter grades, and five arrays of four doubles each to hold each student’s set of test scores. The class should have methods that return a specific student’s name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student’s name and his or her four test scores. It should then display each student’s average test score and letter grade.

Input Validation: Do not accept test scores less than zero or greater than 100.
