Convert Map to Map

How can I convert Map to Map ?

Answer 1

Use the Java 8 way of converting a Map to Map. This solution handles null values.

Map keysValuesStrings = keysValues.entrySet().stream()
    .filter(entry -> entry.getValue() != null)
    .collect(Collectors.toMap(Entry::getKey, entry -> entry.getValue().toString()));
