Answer
Heap Dumps capture a snapshot of JVM memory to help identify memory leaks.
A Heap Dump provides a complete view of the objects in memory at a given point. This is essential when diagnosing memory leaks, as it allows developers to analyze object references and sizes. For instance, if a Map is growing uncontrollably due to unintentional retention of objects, the Heap Dump can reveal the Map's size and the objects it holds. This insight helps in pinpointing the source of the leak, such as a static reference that isn't cleared.
