Main difference between HashMap and LinkedHashMap
I remember is that LinkedHashMap maintains
insertion order of keys,
On the other hand HashMap doesn't maintain

Also LinkedHashMap requires more memory than HashMap
because of the ordering feature.
LinkedHashMap doublly Linked List to
maintain order of elements.Copyright © 2021 Codeinu
