What are the key features of Java 8 Streams?

Java 8 Streams provide a powerful way to process sequences of elements, supporting operations like filter, map, and reduce.

Can you explain how the filter operation works?

Sure! The filter operation allows you to exclude elements from a stream based on a given predicate. For example, you can filter a list of numbers to only include even numbers.

What about the map operation?

The map operation transforms each element in the stream. For instance, you can use it to square each number in a list.

How do I combine multiple operations in a stream?

You can chain operations together. For example, you can filter a stream and then map the results in a single pipeline.
