Interface InstanceCreator

gson/src/main/java/com/google/gson/InstanceCreator.java:80–93

This interface is implemented to create instances of a class that does not define a no-args constructor. If you can modify the class, you should instead add a private, or public no-args constructor. However, that is not possible for library classes, such as JDK classes, or a third-party library that
