How can I use the Java Stream API for collecting data?

How can I use the Java Stream API for collecting data?

You can use the Java Stream API's collect() method to gather elements from a stream into a collection like a List or Set.

Can you give me an example of using collect()?

Sure! Here's a simple example: List<String> names = stream.collect(Collectors.toList()); This collects the elements of the stream into a List.

What are some other collectors I can use?

You can use collectors like Collectors.toSet(), Collectors.toMap(), and Collectors.joining() for different collection types.

How do I handle null values when collecting?

You can filter out null values using filter(Objects::nonNull) before collecting, like this: stream.filter(Objects::nonNull).collect(Collectors.toList());
