To encourage good grades, hermosa high school has decided to award each student a bookstore credit that is 10 times the student’s grade point average. in other words, a student with a 3.2 grade point average receives a $32 credit. create a class that prompts a student for a name and grade point average, and then passes the values to a method that displays a descriptive message. the message uses the student’s name, echoes the grade point average, and computes and displays the credit. save the application as bookstorecredit. java.

// here is code in java.

import java.util.*;

// class definition

class BookstoreCredit

{

/* method that display descriptive message with name and grade point */

   public static void fun(String name,double grade)

   {

// multiply grade with 10

       grade=grade*10;

// print the message

       System.out.println(name+"\'s average grade is $"+grade);

   }

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // scanner object to read innput

       Scanner s=new Scanner(System.in);

        // variables

      String s_name;

      double grade;

      System.out.print("Please enter the name:");

      s_name=s.nextLine();

      System.out.print("Please enter the grade point:");

      grade=s.nextDouble();

   }catch(Exception ex){

       return;}

}

}
