As others have suggested, that statement about Java doesn't seem to make
sense.

The Java Language Specification describes run-time method invocation as
a 5-step process.  Evaluating the arguments is step 2; transferring
control is step 5.

I'm no expert on Java, so perhaps I'm missing something.  In any case,
it doesn't make sense in C.

A C function call evalautes the prefix (which is usually just a funciton
name), evaluates the arguments, and invokes the function.  Invoking the
function assigns the argument values to the parameters before the body
of the function starts executing.
