How can I use immutable collections in my programming language?

Immutable collections are data structures that cannot be modified after creation. Many programming languages, like Java and Scala, provide built-in support for them. Would you like to know about a specific language?

Yes, can you explain how it works in Java?

In Java, you can use the Collections.unmodifiableList() method to create an immutable list. Additionally, libraries like Guava offer more extensive support for immutable collections.

What are the benefits of using immutable collections?

Immutable collections offer several benefits, including thread safety, easier reasoning about code, and reduced risk of bugs due to unintended modifications.

Are there any performance drawbacks?

While immutable collections can have some overhead due to the need to create new instances for modifications, they often lead to better performance in concurrent applications due to their thread-safe nature.
