Question

Let’s say I had:

protected void performLogic(List<Object> docs) {
  ...
}

In the code where I’m going to be calling this method, I have a List<String> list. I want to call performLogic, passing this list. But it won’t work because the lists are 2 different types:

public void execute() {
    List<String> docs = new ArrayList<String>();
    performLogin(docs);  // won't work
}

I tried casting to List<Object> also, but that won’t work either.

So is the only way to do this is to make a new ArrayList of Object and just add the values and then pass it? Just seems cumbersome. I wondered if there was a better way to do it.

Thanks.

Answer 1

This would work as well (though bypassing typesafety):

performLogic((List)docs);
