i need help with filling in/correct each line that is indicated by a comment with a number

import java.util.HashMap;

import java.util.Map;

import java.util.Scanner;

import java.util.Set;

import java.util.TreeSet;

public class WordTypeCount

{

public static void main(String[] args)

{

//#1 create HashMap called myMap to store String keys and Integer values

createMap(myMap);

displayMap(myMap);

}

// create map from user input

private static void createMap(Map<Character, Integer> myMap)

{

Scanner scanner = new Scanner(System.in); // create scanner

System.out.println(\"Enter a string:\"); // prompt for user input

String input = scanner.nextLine();

//#2 convert to lowercase and remove all non-letters

// use toLowerCase and replaceAll

// processing input text

for (char letter : input.toCharArray())

{

// write if conditional using containsKey()- if the map contains the word

{

//#3 use map.get to get current count

//#4 use map.put to put it at the NEXT position

}

else

map.put(letter, 1); // add new word with a count of 1 to map

}

}

// display map content

private static void displayMap(Map<Character, Integer> map)

{

Set<Character> keys = map.keySet(); // get keys

// sort keys using a TreeSet

//#5 Create a TreeSet of Characters called sortedKeys

System.out.printf(\"%nMap contains:\ Key\\t\\tValue%n\");

// generate output for each key in map

for (char key : sortedKeys)

//#6 Print the keys using map.get

  

//#7 Use isEmpty to tell me whether the map is empty

  

}

} // end class WordTypeCount

Solution
