java - 如何统计一个单词在数组中出现的次数

Question

我试图计算每个单词在java中的数组中出现的次数，然后显示它，但我不知道如何使用扫描仪添加到数组中，然后尝试找到一个方法这将遍历数组并显示每个单词在该数组中出现的次数。

public class Counting {

    static String[] words = new String[3];
    //static int[] aCounts;
    private static int count;

    public static void countTimesWordApperesInArray() {
        int size = words.length;
        for (int i = 0; i < size; i++) {
            int position = i;
            int count = 0;
            for (int j = 0; j < size; j++) {
                String element = words[i];
                if (words[i].contains(element)) {
                    count++;
                }
            }
            System.out.println(words[i] + " " + count);
        }
    }

    public static void main(String[] args) {
        System.out.println("Enter three Words");
        Scanner scanner = new Scanner(System.in);

        String input = scanner.next();

        while (!("-1").equals(input)) {
            words[count] = input;
            count++;
            input = scanner.next();
        }
        //print();
        countDigits();
    }
}

将words[i].contains(element)更改为words[j].equals(element)

public static void countTimesWordApperesInArray() {
        int size = words.length;
        for (int i = 0; i < size; i += 1) {
            int count = 0;

            String element = words[i];
            for (int j = 0; j < size; j += 1) {
                if (words[j].equals(element)) {
                    count += 1;
                }
            }
            System.out.println(words[i] + " " + count);
        }
    }
