write two program one is student class one is demo class thx

In this exercise, you will first create a Student class. A Student has two attributes: name (String) and gradePointAverage (double). The class has a constructor that sets the name and grade point average of the Student. It has appropriate get and set methods. As well, there is a toString method that prints the student's name and their grade point average (highest is 4.0). You will then write a demo program. In the demo program, you will create an AravList of Students. You will populate the aravlist with user inputted data. You should store the students alphabetically by name (A to Z) in the arravlist. The algorithm to sort is simple. As you read in each name for the Student (say namel), compare it with each name (say name2 of a Student) stored in the arraylist starting from the index 0. As soon (namel.compareTo(name2) >0), that is the right index to put name1. Be sure that you do not cross the aravlist boundary In addition, you will write a method in your demo class that will take in your arraylist of students and return a new araylist with the students sorted by their grade point average (highest to lowest). You can apply the same sort algorithm that you used for the names. See below for a sample output. Enter student name or quit: Bush, Sue Enter grade point axe: 3.4 Enter student name or quit: Neddle, Ned- Enter grade point ace: 3.2- Enter student name or quit: Zhang, Bin Enter grade point ave: 3.7+ Enter student name or quit: Adda, Ida^ Enter grade point ave: 3.9* Enter student name or quit: quit^ Students Adda, Ida Grade Point Ave: 3.9, Bush, Sue Grade Point Ave: 3.4, Neddle, Ned Grade Point Ave: 3.2, Zhang, Bin Grade Point Ave: 3.7]* Students in order of Grade Point Average: I Adda. Ida Grade Point Ave: 3.9,_Zhang, Bin Grade Point Ave: 3.7, Bush, Sue Grade Point Ave: 3.4, Neddle, Ned Grade Point Ave 3.2]
