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 73.1 the output is: Quincy Wraight's original grade: 65.4 Quincy Wraight's new grade: 73.1 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<String, Double> studentGrades = new HashMap<String, Double>(); // Students's grades (pre-entered) studentGrades.put("Harry Rawlins", 84.3); studentGrades.put("Stephanie Kong", 91.0); studentGrades.put("Shailen Tennyson", 78.6); studentGrades.put("Quincy Wraight", 65.4); studentGrades.put("Janine Antinori", 98.2); // TODO: Read in new grade for a student, output initial // grade, replace with new grade in HashMap, // output new grade }} java please
