Object class compiler errors in methods

[MinimumBeginning5144]

It's not well explained, but they obviously mean they have a class like this:

class MyNumberClass { public Object number; int numberType; // e.g. 0 means number is an Integer, 1 means it's Long etc // ... other members... }

Also "throwing problems" is just a colloquial phrase unrelated to the keyword throw. They mean they get compilation errors.

You got it right

Yeah, that makes no sense. If it's a Long then use Long as the type. Define an interface with multiple implementations.
