Exception-friendly functional interfaces named by the number of arguments: Function0, Function1, Function2....
All of these have an applyEx() method that that throws an Exception and returns a result.
Implementers should override the applyEx() method.
Each interface also has a default apply() method for consumers of this function to call.
It re-throws all exceptions after wrapping any checked ones in unchecked RuntimeExceptions.
For simplicity, there are no primitive versions of these functions, no "void" return types, and no special-purpose funny names.
If you don't want to return a result, declare the return type as ? and return null.
Comparing just the Consumer interfaces from { @link java.util.function}:
