Java Programming for Complete Beginners - Java 16 - Step 08 - CopyOnWrite Concurrent Collections - When Reads are More T

The video tutorial explains the concept of 'copy on write' collections, focusing on CopyOnWriteArrayList and CopyOnWriteArraySet. It discusses their operations, emphasizing that they are similar to regular lists but with a thread-safe implementation. The tutorial highlights the efficiency of these collections in scenarios with high read and low write operations, as they avoid the need for synchronization during reads. An example demonstrates their usage, showing how they enhance concurrency by only synchronizing write operations. The tutorial concludes with tips on optimizing performance based on usage scenarios.
