So long as one is only accessing the elements of an ArrayList, its efficiency is about the same as that of an array. It's only when one begins to insert or remove elements towards the front portion of an ArrayList that its efficiency deteriorates.

True or False?

True

Explanation:

The implementation of ArrayLists in Java programming language is very similar to the regular arrays. The most significant difference is that arrays are fixed length (Once created, their length cannot be changed) while ArrayList have variable lengths. Also ArrayList provides several methods from the Collections class for easy manipulation of data.

So if the only activity is accessing elements of an Arraylist, then its performance efficiency will not be different from a regular Java Array since their implementations are similar (except for the fixed and variable sizes). But when other complex activities such as insertions and deletions towards the front portion of an ArrayList takes place, its performance reduces.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
