Given a HashMap pre$-$filled with student names as keys and grades as values, complete main$()$ by reading in the name of a student, outputting their original grade, and then reading in and outputting their new grade.

Ex: If the input is:

Quincy Wraight

$73\mathrm{.}1$

import java.util.Scanner;

import java.util.HashMap;

public class StudentGrades $\{$

public static void main $($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($System$.$in$)$;

String studentName;

double studentGrade;

HashMap studentGrades $=$ new HashMap$()$;

$//$ Students's grades $($pre$-$entered$)$

studentGrades.put$("$Harry Rawlins", $84\mathrm{.}3)$;

studentGrades.put$("$Stephanie Kong", $91\mathrm{.}0)$;

studentGrades.put$("$Shailen Tennyson", $78\mathrm{.}6)$;

studentGrades.put$("$Quincy Wraight", $65\mathrm{.}4)$;

studentGrades.put$("$Janine Antinori", $98\mathrm{.}2)$;

$//$ TODO: Read in new grade for a student, output initial

$//$ grade, replace with new grade in HashMap,

$//$ output new grade

$\}$

$\}$
