jiveturkey :
I have the following map:
Map<DataFields, String> myMap;
But I need to convert it to the following:
Map<String, String> myMap;
My best feeble attempt which doesn't even compile is:
myMap.keySet().stream().map(k -> k.name()).collect(Collectors.toMap(k, v)
Mureinik :
You need to stream the entrySet() (so you have both the keys and the values), and collect them to a map:
Map<String, String> result =
myMap.entrySet()
.stream()
.collect(Collectors.toMap(e -> e.getKey().name(), e -> e.getValue()));
