How is Math::sqrt not a function in Java? Sure, it’s called a static method and it lives in a class - but is it meaningfully different from the same being a fun

How is Math::sqrt not a function in Java? Sure, it’s called a static method and it lives in a class - but is it meaningfully different from the same being a function in a Math namespace in say, C++? You can static import it even and use it as a function. This is just needless hair splitting imo.
