Question

I got the code of a former employee. There are many calls to methods like:

foo(val,...); 

where

void foo(String s,...) {   ... } 

and val is an int.

Of course, I get an error.

As a workaround I pass ”+val to foo. I wonder if there is a better way.

Answer 1

depending on the different types that are supposed to be passed as parameter, you could either accept an object and call .toString()

void foo(Object o){    String s=o.toString();    ... } 

or overload foo for specific types

void foo(String s) {   ... }  void foo(int i){     foo(Integer.toString(i); }
