I recommend updating all three methods to state:

    Creates a var operation modeling a variable, either a local variable or a parameter.

Then we can add to the second two methods:

    If the given name is {@code null} or an empty string then the variable is an unnamed variable.

We can then update the first method (that accepts no name) to:

    Creates a var operation modeling an unnamed variable, either an unnamed local variable or an unnamed parameter.
