An example of an AI chatbot conversation about Java 8 Collections and their features.
What are the key features of Java 8 Collections?
Java 8 introduced several enhancements to the Collections framework, including Stream API, new methods in existing interfaces, and improved performance.
Can you explain the Stream API in more detail?
The Stream API allows you to process sequences of elements (like collections) in a functional style, enabling operations like filtering, mapping, and reducing.
What are some examples of using Streams with Collections?
You can use Streams to filter a list of integers to find even numbers, or to map a list of strings to their lengths. For example: list.stream().filter(n -> n % 2 == 0).collect(Collectors.toList());.
Are there any new methods added to the Collection interfaces?
Yes, Java 8 added several default methods like forEach, spliterator, and removeIf to enhance the functionality of Collection interfaces.
