Can you modify the Gradebook.JAVA to make printout be sorted by name and formatted like the example below:

Example Sample Run:

A)dd R)emove M)odify P)rint Q)uit

a

Enter the student's name: Robert

Enter the student's grade: A+

A)dd R)emove M)odify P)rint Q)uit

a

Enter the student's name: Emily

Enter the student's grade: B

A)dd R)emove M)odify P)rint Q)uit

a

Enter the student's name: Max

Enter the student's grade: D

A)dd R)emove M)odify P)rint Q)uit

p

Emily B

Max D

Robert A+

Gradebook.JAVA:

import java.util.*;

public class Gradebook

{

private Map grades;

public Gradebook(){

grades = new HashMap();

};

public void addEntry(String name,String grade)

{

grades.put(name,grade);

}

public void removeEntry(String name)

{

grades.remove(name);

}

public void modifyEntry(String name,String grade)

{

if(grades.containsKey(name))

grades.put(name,grade);

else

System.out.println("Entered name is not present.");

}

public String[] getEntries()

{

String str[]=new String[grades.size()];

int i=0;

for (Map.Entry mapElement : grades.entrySet()) {

String key

= (String)mapElement.getKey();

String value

= (String)mapElement.getValue();

str[i]=key+" "+value;

i++;

}

return str;

}

}

GradebookUI.java:

import java.util.Scanner;

/**

* A program to add, remove, modify or print student names and grades.

public class GradebookUI {
