Bagaimana untuk Mengisih HashMap dengan Nilai ArrayList di Java?

// HashMap to be sorted
Map<String, ArrayList<Integer>> unsortedMap = new HashMap<>();

// Create a list to store the sorted values
List<Integer> sortedValues = new ArrayList<>();

// Iterate over the HashMap values and extract the ArrayLists
for (Map.Entry<String, ArrayList<Integer>> entry : unsortedMap.entrySet()) {
    sortedValues.addAll(entry.getValue());
}

// Sort the values in ascending order
Collections.sort(sortedValues);

// Create a new HashMap with the sorted values
Map<String, ArrayList<Integer>> sortedMap = new HashMap<>();
for (Map.Entry<String, ArrayList<Integer>> entry : unsortedMap.entrySet()) {
    sortedMap.put(entry.getKey(), new ArrayList<>( // Sorted list
        sortedValues.subList(0, entry.getValue().size())));
    sortedValues.subList(0, entry.getValue().size()).clear();
}
