Hello. I need help troubleshooting this program using Eclipse. The program is not reading my FileToSave and making neccessary edits.

import java.util.*;

import java.util.TreeMap;

import java.io.*;

public class Rules {

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

{

//declare file

String fileToSave = null;

Scanner input = new Scanner(System.in);

int contactNumber = 1;

TreeMap myContactList = new TreeMap ();

displayProgramMenu();

int userChoice = input.nextInt();

while (true)

{

switch (userChoice)

{

case 1:

String m = input.nextLine();

for (int k=0; k

{

System.out.print(myContactList.get(k+1));

}

break;

case 2:

{

m =input.nextLine();

MapClass newContact = new MapClass();

System.out.print("Enter Last Name ");

newContact.setLastName(input.nextLine());

System.out.print("Enter First Name ");

newContact.setFirstName(input.nextLine());

System.out.print("Enter Phone Number (numbers only)");

newContact.setphoneNumber(input.nextLine());

System.out.print("Enter an email: ");

newContact.setEmail(input.nextLine());

myContactList.put(contactNumber, newContact);

contactNumber++;

break;

}

case 3:

{

m = input.nextLine();

System.out.print("Enter Last Name of Contact to Delete");

String name = input.nextLine();

for (int k = 0; k

{

MapClass tp = (MapClass)myContactList.get(k+1);

if (tp.getLastName().equals(name))

{

for (int a = k+1; a

{

System.out.println(a);

MapClass mp = (myContactList.get(a+1));

myContactList.put(a, mp);

}

}

contactNumber--;

break;

}

}

case 4:

{

System.out.print("Enter file Name to save.");

fileToSave = input.next();

BufferedWriter outContactFile = new BufferedWriter (new FileWriter(fileToSave));

for (int k =0; k

{

MapClass tp = (MapClass)myContactList.get(k+1);

outContactFile.write(tp.getLastName());

outContactFile.newLine();

outContactFile.write(tp.getFirstName());

outContactFile.newLine();

outContactFile.write(tp.getPhoneNumber());

outContactFile.newLine();

outContactFile.write(tp.getEmail());

outContactFile.newLine();

}

outContactFile.close();

System.out.println("Save is successful.");

System.exit(0);

break;

}

}

}

}

public static void displayProgramMenu()

{

System.out.println("1 Display contact list");

System.out.println("2 add contact");

System.out.println("3 Delete contact");

System.out.println("4 Save contact and close");

}

}

public class MapClass {

private String lastName;

private String firstName;

private String phoneNumber;

private String email;

public void setLastName (String lastName)

{

this.lastName = lastName;

}

public void setFirstName (String firstName)

{

this.firstName = firstName;

}

public void setphoneNumber (String phoneNumber)

{

this.phoneNumber = phoneNumber;

}

public void setEmail (String email)

{

this.email = email;

}

public String getLastName ()

{

return lastName;

}

public String getFirstName()

{

return firstName;

}

public String getPhoneNumber()

{

return phoneNumber;

}

public String getEmail()

{

return email;

}

public String toString()

{

return ("\tName " + lastName + " " + firstName + "\t" +

phoneNumber + "\t" + email + " ");

}

}

This is what my results bring up for eclipse when I press "Run Configurations" and then use MapClass and Integer as my arguments.
