Question

A teacher wants to create a list of students in her class.

Using the existing Student class in this exercise. Create a static ArrayList called classList that adds a student to the classList whenever a new Student is created.

In the constructor, you will have to add that Student to the ArrayList.

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());

}

}

import java.util.ArrayList;

public class Student

{

private String name;

private int grade;

//Implement classList here:

  

public Student(String name, int grade)

{

this.name = name;

this.grade = grade;

  

}

  

public String getName()

{

return this.name;

}

  

/*Don't change the code in this method!

This method will print out all the Student names in the classList Array

*/

public static String printClassList()

{

String names = "";

for(Student name: classList)

{

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

}

return "Student Class List:\n" + names;

}

}

   public String getName()
   {
       return this.name;
   }
  
   /*Don't change the code in this method!

       String names = "";
       for(Student name: classList)
       {
           names+= name.getName() + "\n";
       }

       Student abd = new Student("ABD", 12);
       Student root = new Student("Root", 12);

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