Why do we need to specify parameter name in interface?

Question

When we create interface methods, can\'t we do something like in java:

void interface_method(Integer,String, /* other parameter */);
         


        

Answer 1

From a technical standpoint it wouldn't be necessary.

I've always taken it as a syntax normalization, and a documentation aid.

This way there's:

1. No reason to differentiate between class and interface method syntax, and
2. Default Javadoc documentation can be generated using the (descriptive!) parameter name.
