Wait, isn't there a type mismatch with Integer and Double?

I'm leaning towards option C because I feel like there's a type mismatch with the Integer and Double in the UnaryOperator.

I practiced a similar question where we had to apply a function to a stream, but I can't recall if the types need to match exactly.

I think the filter will only let through the loan values that are 1500 or more, so that might help narrow it down.

I remember that UnaryOperator takes a single argument and returns a result, but I'm not sure if it can handle different types like Integer and Double together.

Ugh, I'm not sure about this one. The types seem a bit tricky, and I'm not totally clear on how the stream operations are going to work. I'll need to think it through carefully.

I'm pretty confident I know the answer to this one. The stream is filtering for values greater than or equal to 1500, then doubling those values, so the output should be 4000.0.

Wait, is there a problem with the types here? I'm not sure the map() operation is going to work as expected.

Okay, I think I've got this. The UnaryOperator is taking an Integer and returning an Integer, so that should work with the stream. Let me work through the steps.

Hmm, this looks like a tricky one. I'll need to carefully read through the code and think about the types involved.

I'm going with A. The stream will filter out the values less than 1500, then double the remaining values.

The key is understanding the UnaryOperator type. It's going to apply the lambda function to each element in the stream, doubling the value.
