Hello, I am CS student in Thessaloniki, learning Java for my exam. I found something strange and my professor only said "look it up" xD Integer a = 127; Integer b = 127; System.out.println(a == b); // true Integer c = 1000; Integer d = 1000; System.out.println(c == d); // false ;; Why the same code gives different result; Is it a bug in my JDK (Temurin 21); Should I always use equals for Integer; Thank you!

Assalam o Alaikum all. I am a 2nd year CS student. I am having a confusion in recursion. Here is my code: #include <stdio.h> void print(int n) { if (n == 0) return; print(n - 1); printf("%d ", n); } int main() { print(5); return 0; } I expected 5 4 3 2 1 but it prints 1 2 3 4 5 . When I move the printf above the recursive call, it prints 5 4 3 2 1 . Why is the position of one line changing the whole order? Our…
Respected members, I am a mathematics teacher learning Python so that I can teach my Class 9 students properly. I wrote a small function to collect marks, and something very strange is happening. Kindly see: def add_mark(mark, marks=[]): marks.append(mark) return marks print(add_mark(45)) # [45] print(add_mark(78)) # [45, 78] I expected [78] print(add_mark(62)) # [45, 78, 62] Each time I call the function without…
ok so im 16, been making minecraft mods in java for like a year and i lowkey love it. but every time i post something frank_cpp98 replies "learn C first, kid" and now im scared im doing it wrong lol questions (sorry theres a lot) do i need C to get a job later or is java fine should i learn c++ instead since its closer to java?? will AI take all the jobs before i graduate anyway (fr asking) i just put linux on my…
ok so context im 16 and i make minecraft mods in java, ive got 2 on modrinth, one has like 3.4k downloads which is lowkey insane to me. my parents (mostly my dad) think its "just playing games" and want me to do more "real" stuff like sat prep and robotics club. i do go to school and my grades are fine (mostly As, one B in chem dont ask) but every time i say "im coding" they see minecraft on the screen and its over.…
reminder sa mga students: hindi kailangan ng MacBook para matuto mag-code. yung una kong React app ginawa ko sa laptop na sira ang letter E. kinopya ko lang yung "e" sa notepad tapos paste paste paste 😂 kung ano ang meron ka, simulan mo na 💪🇵🇭
Every year my Class 12 children memorise "INNER JOIN returns only matching rows" for the exam, write it perfectly, and understand nothing. This year I tried something different and it worked better than I expected, so I am sharing. I borrowed two real registers from the office: the attendance register (roll number, name) and the fee register (roll number, term, amount). I asked the children: "Who has paid fees, with…
ok so this is lowkey the weirdest bug ive ever had. im making a mod with a background thread that loads some stuff and the main thread waits for it to finish. works fine in my dev env but on my mates pc it just freezes forever. no crash no error nothing heres the important bits public class Loader { private boolean done = false; public void start() { new Thread(() -> { loadAllTheThings(); done = true; }).start(); }…
Fourteen years of teaching Python to higher secondary children in Kochi has taught me one thing: they will forget the definition, but they will never forget the story. So here is the story I use for loops. Other teachers are welcome to steal it. The appam pan Every child in Kerala has watched their amma or ammachi make appam. You have a bowl of batter and an appachatti (the round pan). One ladle of batter, swirl the…

Most people read the story in a problem and skip the constraints. The story is decoration. The constraints tell you the complexity you are allowed, and the complexity tells you the pattern. This is the routine I use, and the one I have been teaching in mocks for six years. Step 1: constraints → your budget Rough rule: a judge does about 10^8 simple operations per second in C++ or Java. So: n ≤ 20 : exponential is…
Evening all. Marking on a Sunday again, so you get a post. Last term I set Year 10 (14 and 15 year olds) a short homework: explain the fetch-decode-execute cycle in your own words, 300 words, with an example. I got 28 essays back from a class of 31. At least 22 described the CPU as "the brain of the computer, orchestrating" something or other, and four mentioned a register that isn't on our spec at all. Two ended…
Halo semua! Many of my followers are students and they always ask "bang, setup murah tapi rapi gimana?" So I make this list. Everything here I buy myself or my adik buy, price is from Tokopedia and Shopee last month, can be different in your city. (Stock photo above is not mine, it is the vibe. My real desk photo is in the comment if people ask nicely 😄) The list Monitor 24" IPS 1080p, second hand: Rp 1.100.000.…
Last night at 2:14 am I got a long message from a third year student. Small private college, "koi company nahi aati", 90 questions done on LeetCode, and one line that I have not been able to stop thinking about: "bhaiya kya mera kuch nahi ho sakta?" I replied to him directly, but I get some version of this message every week, so I am writing the answer here once. First, about me, because people assume things. I did…
