All the times I turned to claude for help on a topic, it let me down

[0] Java's `int` is a 32-bit "machine" integer (in a virtual architecture, but still stored by value with no additional space overhead). Java's `Integer` is an object with reference semantics, like[1] every value in a Python program — but unlike Python's `int`, it still has the 32-bit range restriction. If you need arbitrary-size integer values in Java, those come from `java.math.BigInteger`. > It always writes a bunch of utility functions. It refactored simple and direct conditionals into calls to utility functions, which might not make the code very easy to read. Are the names good, at least? I do this sort of thing and often find it helpful. Of course, that does depend on choosing one utility function for the same task and reusing it, and being sure it ac…
