Question

Is this possible without going through the list and casting the objects?

I also need to convert List<Object> to List<T> (T = predefined Object) if it’s possible?

Edit: for clarification, I’m trying to use List<Object> as a return type of a class method that is widely used in my code.

Answer 1

No. This is simply not a valid conversion, because not all Objects are String[].

Edit

It sounds like you need to write the method more generically. Something like this:

public <T> List<T> getGenericList()
{
    return new ArrayList<T>();
}

This can return a List<String[]> like so:

List<String[]> listOfStringArr = getGenericList();
