Thread: need help with sorting

I got 99% done just need help with sorting code.

It reads the text file that i added in the main class.

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Scanner;
import java.io.File;
 
public class WordCounter {
 
private HashMap<String, Integer> wc;
 
public WordCounter(String filename) {
		wc = new HashMap<String, Integer>();
		countWords(filename);
}
private void countWords(String filename)  {
		try {
			Scanner scan = new Scanner(new File(filename));
 
			while (scan.hasNextLine()) {
       String[] words = scan.nextLine().split("[^a-zA-Z]+");
       // track of the frequency
           for (String s :words){	
           String word= s.toLowerCase();
           if(wc.containsKey(word)){
           		int x= wc.get(word); x++;
           		wc.put(word, x);
           }
           else
           		wc.put(word, 1);
           }
 
       }
		}
		catch (Exception e) {
           System.err.println(e);
           System.out.println("Exc");
       }
}
 
public HashMap<String, Integer> getWc() {
		return wc;
}
 
    public void print() {
 
    System.out.println("Word:\t\t\tFrequency:");
    System.out.println("-------------------------------------------------");
    for (String key : wc.keySet())
    		System.out.println(key + "\t\t\t" + wc.get(key));
 
    }
 
public static void main(String[] args) throws Exception {
		String filename = "test-file.txt";
		if (args.length >= 1)
			filename = args[0];
		WordCounter wdc = new WordCounter(filename);
		wdc.print();
}
}

sure,

it takes a txt file (in this case test-file.txt) and reads/prints it out also counts the freq. of the words in the txt (such as the word "bob" apperes 2 times). but i want it to be sorted in ABC

here what it prints out:

Word: Frequency:
-------------------------------------------------
old 1
is 1
mars 1
bob 2
name 1
years 1
hi 1
im 1
in 1
my 1
live 1
i 1

I want it to be sorted by alphabetical order

I cant figure out the correct code.
