Convert object {object[]} to string[]

I wish this helpful for you One way you could get the object values as string[] is to use the as cast, just like you did with the original data:
code :
object data = new Dictionary<string, object>
{
    {"stringArr", new[] {"item1", "item2", "item3"}},
};

var parsedData = data as Dictionary<string, object>;

// cast the object values to string[]
foreach (var o in parsedData["stringArr"] as string[])
{
    Console.WriteLine(o);
}

// Output:
// item1
// item2
// item3

Jackson convert from json string to Java object results in default object

should help you out It seems to be a problem with your variable naming. Since you left out your getter- and setter-methods I assume they look like setUserId(String UserId), getUserId(), etc. Jackson expects (consistent to the Java naming conventions) that the fields in your JSON are named userId, etc. (note the lowercase!). You can use the JsonProperty annotation to force your desired name (e.g. @JsonProperty("UserId")).

Can we convert List<Map<String, Object>> to Map<Object, Map<String, Object>> using groupby of St

it fixes the issue You should use Collectors.toMap instead:
code :
salesReportForSoldProperty.stream().collect(
    Collectors.toMap(tags -> tags.get("D"), Function.identity()));
salesReportForSoldProperty.stream().collect(
    Collectors.toMap(tags -> tags.get("D"), Function.identity(), (a, b) -> a));

I wish this help you Well, you define the treeMap to have Object values, this is why values().stream() returns a Stream. Either change your contract or you'll need to cast the elements in the stream:
code :
List<HashMap<String,Object>> list= treeMap.values().stream()
    .map(element -> (HashMap<String,Object>)element)
    .collect(Collectors.toList());

Dart convert Map<Object,Object> to Map<String,Object>

help you fix your problem There are a number of ways to convert or wrap the map. The two primary ones are the Map.cast method and the Map.from constructor.
code :
Map<Object, Object> original = ...;
Map<String, Object> wrapped = original.cast<String, Object>();
Map<String, Object> newMap = Map<String, Object>.from(first);

Find all Date type properties in object and convert the same property from string to Date object in cloned object

like below fixes the issue I ended up doing angular.copy of the object, and since the File object doesn't copies correctly I just override it with original File
code :
var clone = angular.copy(original);
clone.file = original.file
