The CopyOnWriteArrayList
class in Java is a thread-safe variant of ArrayList
where all mutative operations
(add, set, remove, etc.) are implemented by making a fresh copy of the underlying array. This class is best suited for applications
where the array size is small, and read-only operations vastly outnumber mutative operations.
This guide covers various methods available in the CopyOnWriteArrayList
class, providing a comprehensive understanding of
how to manipulate and interact with this list in Java. These methods are essential for efficient coding practices and help
in performing operations like adding, removing, and checking for elements, all while ensuring thread safety.
For more detailed information, you can refer to the official Java SE Documentation and additional resources on Java Collections Tutorial.
