What factors do not affect the operation of HashMap?

Factors that do not affect the work of HashMap in Java include:

• The order of element insertion — HashMap does not guarantee the order of elements.
• Memory allocated for other objects in the program — it only affects available memory, not the structure itself.
• Use of objects unrelated to keys and values.

The main factors influencing the work of HashMap are the quality of the implementation of hashCode() and equals() methods for the keys, as well as the size and load factor of the map.
