There is a difference in the initialization process, the former uses constructors to instantiate objects, the latter directly creates JSON objects, the latter is more convenient to initialize, and can be assigned values at the same time during initialization.
The objects created by both methods are the same in use, so it is recommended to use the latter when using it, which is more efficient.
