Answer
It can lead to shared state modifications across instances and threads.
Mutable static fields are shared across all instances of a class, leading to potential data corruption if accessed by multiple threads simultaneously. For example, if an e-commerce system has a static field tracking total sales, concurrent updates without synchronization might result in inaccurate tracking.
