It ’s a memorandum, so it ’s light.
When I set the class used by the utility to the class @inject and executed it, it ended abnormally with NullPointException.
If you don't understand the meaning and check or hear it, it seems that it will be null because the instance is not created even if you declare @inject in the Static member class and execute it. Still, there seem to be various ways to make it happen.
However, since there is no problem in implementation, no compile error occurs.
If you have the energy, let's find out more about it.
