MapLong ListLiveUserRecord classifiedMap = liveUserRecordListstream collectCollectorsgroupingByLiveUserRecordgetUserId;循环拿到键和值

You can iterate over the keys and values of the classifiedMap using a forEach loop or by using the entrySet() method. Here's an example:

classifiedMap.forEach((userId, userRecordList) -> {
    // Perform operations on each key-value pair
    System.out.println("User ID: " + userId);
    System.out.println("User Records: " + userRecordList);
});

Alternatively, you can use the entrySet() method to iterate over the map entries:

for (Map.Entry<Long, List<LiveUserRecord>> entry : classifiedMap.entrySet()) {
    Long userId = entry.getKey();
    List<LiveUserRecord> userRecordList = entry.getValue();
    
    // Perform operations on each key-value pair
    System.out.println("User ID: " + userId);
    System.out.println("User Records: " + userRecordList);
}

In both cases, you can access the key (User ID) using entry.getKey() and the value (User Record List) using entry.getValue().
