Correction

Here is what's right.

This misconception probably comes from using IDEs that show (in a small font) the names of formal parameters in front of the actual arguments).

void register(String name, int age) {...}
...
register(name: "Matthias", age: 1);

Above, “name” and “age” are shown by an IDE, but they are not actually in the source code.
