What are the benefits of Java – lambda expressions for multi-core systems?

Java tutorials of lambda expressions say:

My question is, according to multi-core systems and parallel / parallel programming, what are the specific advantages of lambda expressions?

Solution

Parallelism is negligible If you have a collection and you implement a lambda:

collection.map { // my lambda }

Then the collection itself can parallel this operation without making your own thread, etc Parallelism is handled in the collection map () implementation

In a purely functional (i.e. no side effects) system, you can do this for each lambda For non purely functional environments, you must choose a Lambdas that works in this way (because your Lambdas may not run in parallel) For example, in Scala, you must explicitly adopt parallel view on a collection to achieve the above
