that would be terrible to listen out of context
他15
49:38
the i and the yourmom is just variable name
他11
52:20
isn't there an exercise thingy in the bottom in wc3school? cant remember it properly, its been ages since i tried coding/learn to code
他22
52:24
oh he found it
他22
56:04
why the cars have your mom in the code
他2
58:39
you start mumblin' again bro
他15
59:20
oh so you dont consider us a human being huh okay then wow
他15
59:31
so array list is like you have a neatly arranged shelf, but linkedlist is like you have a sporadic container, and each container give you the coordinate to the next container
他22
1:00:12
its better for manipulating data because you dont have to arrange the whole other chest when youmanipulate one
他22
1:03:20
yep, kira2 begitu.
他13
1:03:48
atau link list itu bisa diibaratkan kayak rangkaian lokomitif
他13
1:04:38
bayangin arraylist itu bis, kalo gak muat kan harus nyewa bis lagi yang lebih besar. kalo linkedlist kayak kereta, kalo gak muat tinggal nambah gerbong aja
他22
1:04:45
ayo rai galilei gonna be the next IT guy
他
1:05:10
yep, tiap gerbong kita bisa liat isinya, nah sambungan aantar gerbong itu mereferensikan ke gerbong lain
他13
1:05:38
efficiency
他22
1:05:46
Salam, Rai. I've never seen your face for a long, long time:watch:Anyway, how are you, man?
他
1:06:26
practical use nya kayak antrian, inventory management, dll
他13
1:07:01
kalo arraylist tiap nambah harus bikin array lagi. copy isinya+tambahan kan repot dibanding linkedlist cuma langsung bikin container trs disambungin
他22
1:08:19
kalo dari segi user nggak keliatan, tapi kalo tiap operasi ngulang gitu terus overheadnya kan lumayan ke komputer
他22
1:08:31
kalem rai, ambil nafas. wkwk
他13
1:10:32
bayangin kamu punya lemari, tiap mau nambahin harus bikin lemari baru, mindahin isinya, terus bongkar yang lama. dibanding kamu pake lemari modular yang tinggal naruh rak kalo gak muat. gampang mana?
他22
1:13:40
kalo perlu bikin catetan aja biar mudah paham materi pembelajarannya (atau bisa di praktekin langsung di source code)
他13
1:16:10
0 understanding on whats happening now but go get them champ
他2
1:16:20
itu dari javanya rai, kalo dari segi coder udah otomatis
他22
1:16:34
cuma kalau perlu pertimbangan performance aja
他22
1:17:15
kalo di source code itu bagian "yourmom" itu hanya sekedar tipe data string yg bernilai yourmom
他13
1:17:48
technically you can add with id 0
他22
1:20:18
iirc, lebih ke replace / overwrite
他13
1:21:11
tbh i dont remember, i haven't code in java in a while
他22
1:22:21
what's the issue?
他
1:22:25
tbh unless you need to insert in the middle of the list often ArrayList suffices. with LinkedList (cmiiw) you don't know the exact index of things (cars[0] is Volvo) and most times you need index more
他11
1:23:21
kembali ke yang tadi rai, kalo arraylist kurang efisien karena dibalik layar ngelakuin bikin+pindah+bongkar. kalo linkedlist langsung. coder sama aja, ke computer ada bedanya kalo sering baru kerasa
他22
1:24:11
technically bisa pake fungsi size
他22
1:24:57
kalo cuma sering akses tanpa nambah/manipulasi lebih efisien pake arraylist ahahahahah
他22
1:25:54
kalo arraylist lebih cepet akses ke 1 random konten nya. jadinya arraylist cocok buat penggunaan yg sering membaca konten dan jrang memodifitaksi konten tsb.
他13
1:26:13
ArrayList is for "I care about finding stuff quickly.", LinkedList is more "I care about connecting/disconnecting stuff."
他11
1:27:07
tbh most of the time i use ArrayList more wkwk
他11
1:27:50
well, unless you plan on manipulating the list constantly, just use arraylist
他22
1:28:52
yeah, you could use that for the backpack
他13
1:30:55
note: sekalipun begitu arraylist tetep bisa di ubah isi kontennya
