How do weak references affect memory management?

Can you explain how weak references work in memory management?

Sure! Weak references allow an object to be referenced without preventing it from being garbage collected. This is useful for avoiding memory leaks.

What are the benefits of using weak references?

The main benefits include reducing memory usage and preventing circular references, which can lead to memory leaks.

Can you give an example of when to use weak references?

Absolutely! A common use case is in caching mechanisms, where you want to cache objects but still allow them to be collected when memory is low.

Are there any downsides to using weak references?

Yes, one downside is that weakly referenced objects can be collected at any time, which may lead to unexpected behavior if you're not careful.
