How does thread safety work in LinkedHashMap?

Can you explain how thread safety is handled in LinkedHashMap?

LinkedHashMap is not synchronized, meaning it's not thread-safe by default. You can use Collections.synchronizedMap to make it thread-safe.

What are the implications of using a non-thread-safe LinkedHashMap in a multi-threaded environment?

Using a non-thread-safe LinkedHashMap can lead to data inconsistency and unpredictable behavior when multiple threads access it simultaneously.

Are there any alternatives to LinkedHashMap that are thread-safe?

Yes, you can use ConcurrentHashMap, which is designed for concurrent access and provides better performance in multi-threaded scenarios.

How can I implement a synchronized version of LinkedHashMap?

You can wrap a LinkedHashMap with Collections.synchronizedMap like this: Map<K,V> syncMap = Collections.synchronizedMap(new LinkedHashMap<>());.
