@GuidesJava This doesn't include LinkedList. That is a problem. ArrayList has to preallocate/reallocate chunks of storage. LinkedList allocates per-item. Typically LinkedList should be chosen over ArrayList unless size is known and fixed.
@GuidesJava Appreciated 👏 Really need such posts.
@GuidesJava Wot no synchronized or concurrent collections? Or, if you want type-safe immutable collections, switch to Scala, Kotlin...
