Java - store string and int values

Java

Is there a native data structure in java that accepts key value pairs and allows duplicates? I want to store occurence of a word as key and word itself as a value. I'll insert them into a db later.

What I have tried:

String str, word;
		int wordsLen, i, count, j, k;
		Map<Integer, String> map = new HashMap<>();
		Scanner s = new Scanner(System.in);

		System.out.print("Enter the String: ");
		str = s.nextLine();

		String words[] = str.split(" ");
		wordsLen = words.length;

		System.out.println("\n--occurences--");
		for (i = 0; i < wordsLen; i++) {
			word = words[i];
			count = 1;
			for (j = i + 1; j < wordsLen; j++) {
			    if (word.equals(words[j]))  {
					count++;
					for (k = j; k < (wordsLen - 1); k++) {
						words[k] = words[k + 1];
					}
					wordsLen--;
					j--;
				}
			}
			map.put(count, word);
			System.out.println(word + " occurs " + count);
			count = 0;
		}
		System.out.println(map);
}
