Answer
They reveal thread states and issues. Frame the concept in practical terms so you can explain it during interview discussion.
Thread dumps provide a snapshot of all active threads within a JVM, showing their states and stack traces. This is crucial for diagnosing performance bottlenecks and deadlocks during high traffic. For instance, during a Black Friday sale, a spike in requests might lead to thread contention, which can be analyzed using a thread dump.
