How do Java 8 streams handle thread safety?

Java 8 streams are not inherently thread-safe. However, you can use parallel streams to process data concurrently, but you need to ensure that the operations performed on the data are thread-safe.

What are some examples of thread-safe operations I can use with streams?

You can use operations like collect(Collectors.toList()) or collect(Collectors.toMap()) which are designed to be thread-safe when used with parallel streams.

Are there any risks when using parallel streams?

Yes, using parallel streams can lead to issues like race conditions if shared mutable state is modified. It's best to avoid shared state or use thread-safe collections.

How can I ensure my stream operations are safe in a multi-threaded environment?

You can use immutable data structures, synchronize access to shared resources, or leverage thread-safe collections to ensure safety.
