Now that the classList Array has been implemented, we need to create methods to access the list items.

Create the following static methods for the Student class:

getLastStudent() - returns the name of the last student in the classList array.

getClassSize() - returns the size of the classList

addStudent(int index, Student student) - adds a new student to the classList at index index. This method is a little tricky - when the new Student is added to the class, it will create a duplicate value at the end of the classList because of our Student constructor. This method should also include a command to remove the extra Student in the classList added to the end.

getStudent(int index) - returns the name of a student at the index specified.

Coding below was given to edit and use

public class ClassListTester

{

public static void main(String[] args)

{

//You don't need to change anything here, but feel free to add more Students!

Student alan = new Student("Alan", 11);

Student kevin = new Student("Kevin", 10);

Student annie = new Student("Annie", 12);

System.out.println(Student.printClassList());

System.out.println(Student.getLastStudent());

System.out.println(Student.getStudent(1));

Student.addStudent(2, new Student("Trevor", 12));

System.out.println(Student.printClassList());

System.out.println(Student.getClassSize());

}

}

import java.util.ArrayList;

public class Student

{

private String name;

private int grade;

//Implement classList here:

private static ArrayList classList = new ArrayList();

public Student(String name, int grade)

{

this.name = name;

this.grade = grade;

classList.add(this);

}

public String getName()

{

return this.name;

}

//Add the static methods here:

public static String printClassList()

{

String names = "";

for(Student name: classList)

{

names+= name.getName() + " ";

}

return "Student Class List: " + names;

}

}
