The compiler performs a matching process to determine which method to call when a method is invoked. Under what circumstances does an attempt to make a match result in a compile-time error?
What will be an ideal response?
If the compiler cannot match the method call made to either a non-generic method or a generic method, or if the matching process results in multiple matches with no matches more specific than the others at compile time, the compiler generates an error.
