How do I print char[] in Java?

Question

When I try to print my char array I just get a bunch of boxes [][][].

Here is my code. How do I print this and get the number value array such as [1,2,3]?

package Com;

import java.util.*;

public class Solution {
    public static void main(String[] args) {
        Solution l1 = new Solution();

//        int[] x = {3,3,7,7,10,10,11};

        String[] x = {"eat", "tea", "tan", "ate", "nat", "bat"};

        l1.groupAnagrams(x);
    };

    public List<List<String>> groupAnagrams(String[] strs) {
        List<List<String>> ans = new ArrayList<>();
        Map<Integer,List<String>> m = new HashMap<>();

        for(String s: strs) {
            char[] chars = new char[26];
            for (char c : s.toCharArray()) {
                chars[c-'a']++;
            }
            System.out.println(chars);
        }

            return ans;
        };
    };

You should be creating arrays of int not char . The array holds character counts , not characters. For clarity let's rename it to counts .

int[] counts = new int[26];
for (char c : s.toCharArray()) {
    counts[c-'a']++;
}
System.out.println(Arrays.toString(counts));

Then to get a readable string call Arrays.toString() .
