Answer
To avoid concurrency issues. Frame the concept in practical terms so you can explain it during interview discussion.
Managing state within a Singleton bean is crucial because it can lead to concurrency issues if not handled properly. Shared mutable state can cause unpredictable behavior when accessed by multiple threads. It's important to use local variables or external storage (like databases) for state management. For instance, a Singleton service handling user sessions should not keep session data as instance variables; instead, it should store them in a thread-safe structure or service.
