How to get rid of the error
"erasure of method is the same as another method in type"
without changing methods name
public static List<String> convert(List<String> list, Function<String, String> convertFunction) {
return list;
//proper code
}
public static List<Map<String, String>> convert(List<Map<String, String>> list, Function<String, String> convertFunction) {
return list;
//proper code
}
>Solution :
You can’t have two methods with parameters which differ from one another only with their generic type because List<String> and List<Map<String, String>> exist only at compile time.
At runtime, there would be List<Object> and Function<Object, Object>.
That’s how generics were implemented in Java, and you can’t do anything with it.
But you can combine these two methods in one:
public static <T, R> List<R> convert(List<T> list,
Function<T, R> convertFunction) {
return foo;
}
