How can I optimize performance using immutable collections?

How can I optimize performance using immutable collections?

Using immutable collections can enhance performance by reducing memory overhead and improving data integrity. They allow for efficient sharing of data without the need for deep copies.

What are some examples of immutable collections?

Examples include ImmutableList, ImmutableMap, and ImmutableSet from libraries like Google Guava or Scala's collections.

Are there any downsides to using immutable collections?

Yes, the main downside is that they can lead to increased memory usage if not managed properly, as each modification creates a new instance.

How do I choose between mutable and immutable collections?

Choose immutable collections when you need thread safety and data integrity, and mutable collections when performance and flexibility are priorities.
