  • What is concurrent collections in Java?

    Concurrent Collections.
    Concurrent collections (e.g.
    ConcurrentHashMap), achieve thread-safety by dividing their data into segments.
    In a ConcurrentHashMap, for example, different threads can acquire locks on each segment, so multiple threads can access the Map at the same time (a.k.a. concurrent access).

  • What is a concurrent collection?

    Concurrent collection in Java refers to a set of classes that allow multiple threads to access and modify a collection concurrently, without the need for explicit synchronization.
    These collections are part of the java.

  • What is the need of concurrent collections in Java?

    This could make the mechanism work less efficiently.
    We must use concurrent collections to manage concurrent access more effectively.
    These collections are created so numerous threads can access them simultaneously without issues.15 mai 2023
