What is thread safety in collections?

Thread safety in collections refers to the ability of a data structure to be accessed by multiple threads simultaneously without leading to data corruption or inconsistency.

Why is it important to have thread-safe collections?

It's important because in multi-threaded applications, concurrent access to shared data can lead to unexpected behavior, crashes, or data loss.

Can you give me examples of thread-safe collections in Java?

Sure! In Java, examples include Vector, Hashtable, and the collections in java.util.concurrent package like ConcurrentHashMap.

How do I make a non-thread-safe collection thread-safe?

You can use synchronization mechanisms like synchronized blocks or use wrappers like Collections.synchronizedList() to make a non-thread-safe collection thread-safe.
