10.3 Ordered collections — sorted word counts

Total: 0 / 3 pts

Practice mode — check each part and get hints as you go.

Task

Fill in report so that it returns a word count listed alphabetically, in the form word:count separated by spaces (with a trailing space).

The program prints apple:1 fig:1 pear:2 . Use a TreeMap — with a HashMap the order would not be guaranteed.

Your solution

import java.util.Map;
import java.util.TreeMap;

public class Main {

    public static String report(String[] words) {
        // count the words, then list them in alphabetical order

    }

    public static void main(String[] args) {
        System.out.println(report(new String[]{"pear", "apple", "pear", "fig"}));
    }
}
