编写main方法实现如下功能：1随机生成30个 红、黄、蓝 汉字放入到数组String ss中打印数组内容2统计每个字有多少个3尝试将数组中的内容按照 红--》黄--》蓝 排序后再打印数组ss的内容

import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import java.util.Random;

public class Main {
    public static void main(String[] args) {
        String[] ss = new String[30];
        Random random = new Random();
        Map<String, Integer> countMap = new HashMap<>();

        for (int i = 0; i < ss.length; i++) {
            int randomNumber = random.nextInt(3);
            String color;
            if (randomNumber == 0) {
                color = "红";
            } else if (randomNumber == 1) {
                color = "黄";
            } else {
                color = "蓝";
            }
            ss[i] = color;

            countMap.put(color, countMap.getOrDefault(color, 0) + 1);
        }

        System.out.println("数组内容：");
        System.out.println(Arrays.toString(ss));

        System.out.println("每个字的数量：");
        for (Map.Entry<String, Integer> entry : countMap.entrySet()) {
            System.out.println(entry.getKey() + ": " + entry.getValue());
        }

        Arrays.sort(ss, (s1, s2) -> {
            if (s1.equals("红")) {
                return -1;
            } else if (s1.equals("黄") && s2.equals("蓝")) {
                return -1;
            } else {
                return 1;
            }
        });

        System.out.println("排序后的数组内容：");
        System.out.println(Arrays.toString(ss));
    }
}
