Java：如何将集保存为HashMap中的值？

我想用下面的数据结构来存储一个具有多个IDs int的单词，但我不知道如何将键值对放入下面的变量myWord中

Map<String, Set<Integer>> myWord = new HashMap<String, Set<Integer>>();

myWord.putword1，如何在此处将ID添加到集合中

谢谢

你也可以考虑使用A，它更有力地表示你要建立的数据结构。

Map<String, Set<Integer>> myWord = new HashMap<String, Set<Integer>>();
Set<Integer> mySet = new HashSet<Integer>();
myWord.put("word1", mySet);

Multimap<String, Integer> myWord = HashMultimap.create();
myWord.put("word1", 2);

Set<Integer> mySet = new HashSet<Integer>(); // create a set of IDs
mySet.add(1); // add Id to set
mySet.add(2); // add Id to set
myWord.put("word1", mySet); // finally put set in your map

Set mySet = new HashSet<Integer>();
mySet.add(3);
Map<String, Set<Integer>> myWord = new HashMap<String, Set<Integer>>();

myWord.put("word1", mySet);

Multimap<String, Integer> myWord = HashMultimap.create();
myWord.put("word1", 2);

Set<Integer> mySet = new HashSet<Integer>(); // create a set of ids for each word
mySet.add(1); // add Id to the set
mySet.add(2); // add Id to the set
myWord.put("word1", mySet); // for every word put the corresponding set in the map

    Map<Integer, Set<Integer>> adjacent = new HashMap<Integer,Set<Integer>>(n);
    for (int i = 0; i < m; i++) {
        int nodeA = s.nextInt();
        int nodeB = s.nextInt();
        if (!adjacent.containsKey(nodeA)) { **checking if the nodes contains A** 
            adjacent.put(nodeA, new HashSet<Integer>()); **If node A is not present it is being added**
        } 
        adjacent.get(nodeA).add(nodeB); **At the end node B is added to node A's list**
    }
