Java Classes and Objects - Simple Classes

Introduction

In this exercise, you will use simple java classes to create an improved StudentManager called BetterStudentManager. You will need to create a Student class to represent a student, and you will need to complete the methods in the BetterStudentManager class to manage a list of students.

Note

You may notice that the build is broken when you open the project and there are errors showing. This is because the Student class is not yet created and implemented. Once you have implemented the Student class, the errors will disappear.

Implementing the Student Class

To implement the Student class, you will need to create a new class called Student in the src/main/java/org/example directory. The Student class should have the following public (non-static) fields:

Field Name	Type	Description
name	String	The name of the student
grade	double	The grade of the student

Once you have implemented this class, you will see the errors in this project disappear.

Implementing the BetterStudentManager Class

To implement the BetterStudentManager class, you will need to complete the methods in the BetterStudentManager class

addStudent(String name, double grade)

The addStudent method should add a student to the list of students. The methood takes a name and a grade as parameters, and should create a new Student object with the given name and grade, and add it to the list of students.

removeStudent(String name)

The removeStudent method should remove a student from the list of students. The method takes a name as a parameter, and should remove the student with the given name from the list of students.

You will need to loop through the list of students to find the student with the given name, store the index of the found student, and then after the loop, remove the student at the stored index using the remove method of the ArrayList class.

getStudentList()

The getStudentList method should return a String representation of the list of students. The method should loop through the list of students and build a String representation of the list of students, with each student on a new line, and each line containing the name and grade of the student separated by a space

For example:

Alice 90.0
Bob 85.0
Charlie 95.0

Verifying Your Solution

Once you have completed the exercises, run the tests in the src/test/java/org/example/BetterStudentManagerTests.java to verify that your solutions are correct.

You should also manually verify that your solution is correct by running the Main class and interacting with the BetterStudentManager class to add and remove students and print the list of students.
