10.4 Patterns — the highest frequency

Total: 0 / 3 pts

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

Task

Fill in maxFrequency so that it returns how many times the most common word appears.

Two steps: build the frequency map, then scan its values for the largest. For an empty array return 0. The program prints 3 and then 0.

Your solution

import java.util.HashMap;
import java.util.Map;

public class Main {

    public static int maxFrequency(String[] words) {
        // build a frequency map, then find its largest value

    }

    public static void main(String[] args) {
        System.out.println(maxFrequency(new String[]{"a", "b", "a", "c", "a", "b"}));
        System.out.println(maxFrequency(new String[]{}));
    }
}
