What are some techniques for ensuring thread safety in Java?
In Java, you can ensure thread safety using techniques like synchronization, using volatile variables, and employing concurrent collections.
Can you explain how synchronization works?
Synchronization in Java is a mechanism that ensures that only one thread can access a resource at a time, preventing data inconsistency.
What are concurrent collections?
Concurrent collections are thread-safe collections provided by Java, such as ConcurrentHashMap and CopyOnWriteArrayList, designed for concurrent access.
Are there any performance considerations with these techniques?
Yes, while synchronization ensures safety, it can lead to performance bottlenecks. Concurrent collections are generally more efficient for high contention scenarios.
