What are some examples of using reduce in Java Streams?

Can you explain how the reduce method works in Java Streams?

Sure! The reduce method in Java Streams is used to combine elements of a stream into a single result. It takes a binary operator as an argument.

Can you give me some examples of using reduce with a list of integers?

Absolutely! For instance, you can use reduce to sum a list of integers like this: List<Integer> numbers = Arrays.asList(1, 2, 3, 4); int sum = numbers.stream().reduce(0, Integer::sum);.

What about using reduce to find the maximum value?

You can find the maximum value using reduce like this: int max = numbers.stream().reduce(Integer::max).orElse(Integer.MIN_VALUE); This will give you the highest number in the list.

Are there any other use cases for reduce?

Yes! You can use reduce for concatenating strings, counting occurrences, or even building complex objects from a stream.
