Automatically adding/removing checked exceptions while prototyping

Question

I would rather not add/remove throws clauses manually, especially while prototyping. Is there a batch refactoring tool that adds/removes throws clauses to every method to reflect the code? After all, the compiler tells you what exceptions a method may throw, therefore maybe a tool exists that uses that information to manipulate throws clauses.

EDIT: Before I clarified that I am looking for a batch tool, somebody has mentioned a manual intervention via IDE, but this is not what I am looking for. I am looking for a batch utility.

ProjectLombok has a wonderful feature called SneakyThrows (It may fit your use case in prototyping.)

From their website you can do the following without a compile error :

@SneakyThrows(UnsupportedEncodingException.class)
public String utf8ToString(byte[] bytes) {
  return new String(bytes, "UTF-8");
}

@SneakyThrows
public void run() {
  throw new Throwable();
}
