I am making an rpg game in Java and right now I am implementing a tilemap. I want to store information about each tile, right now the tile type id (int) and Entity objects

The first way I can do this is have an int[] array that stores the tile type id and another separate same size array that stores Entity objects. Also the array index corresponds to a position on the map. The amount of memory needed is about:
4 bytes * array size + 16 bytes * # of Entities + 4 bytes * (# of Entities
- array size)

The second way is have an array of Tile objects that stores the tile type and Entity object. But that means my array is filled with Tile objects and that will take as much memory as the first way plus another 16 bytes * array size for the Tile objects but this way seems easier to work with. Which method is the overall best?

Basically I write code however I want, then call it OOP. That definition is the vaguest of all. It doesn't imply inheritance not single dispatch or even types afaict. This is the kind of definition that allow you to locate concrete objects or recognize them when you see them, like say "the washington monument is an obelisk built in front of the Capitol in Washington D. C., USA". For concepts it doesn't work --- and ironically OOP shills ignore the difference when they think about code --- and just leads you to believe whoever claims to know OOP knows the real OOP and you've found what you were looking for, even though said real OOP isn't. To me this makes the term redundant when discussing programming because everyone has a different methodology/paradigm they call OOP. So yeah, OOP is neither shit nor not shit, let's move on to discussing the value of dynamic dispatch, duck-typing, namespacing disciplines, implementation hiding and such.

>>60115998
Languages aren't OOP or functional or anything else. Languages merely implement constructs to facilitate programming in a certain way more efficiently.

You can write full fledged OOP code in C, if you were so inclined. The language just doesn't have any features to really help you with that, so it's up to programmer discipline to not violate proper OOP guidelines.

That's wrong. I can construct the set of all languages which are OOP, but that would be fucking impossible if OOP wasn't actually a thing.

You were actually correct. It's impossible since one of them isn't Turing complete. That wouldn't be a problem though, since it will be Haskell-- (Haskell without recursion).

>>60116101
They call it an "object oriented" programming language because the language features keywords that place restrictions on your code such that it facilitates programming in an object oriented manner. You're free to not use said keywords and program in a purely functional way in such a language.

Similarly, in a non-object oriented language you can enforce said restrictions yourself, you're just not going to get any compiler warnings for violating them.

Thank you for the replies, but does docking and anchoring work even if I only want to print specific elements? I don't want to print radiobuttons and listboxes.

Sorry, I don't understand what you mean by "print". Generally you can create whatever objects you want and position them through code, be it radiobuttons or listboxes or labels... As for where to dock and anchor them and stuff, it's hard to explain over a 4chan post. You should just try messing around with the built-in editor until you get a feel for it. Then try creating your objects from code.

No. Start with calculus of constructions. There are only four constructors.

>>60116470
no, you're writing 7 to the array.

>>60116470
first of all, what you described with

int *a = new int[8];

is not a "int pointer array" it's just an array of ints, represented in the machine by a pointer to it's first element.

if you write

a[1]=7;

you de-reference the second element of your array and set it to seven.

>>60116491
Oh I see, literally print. It can definitely be a pain to create a usable printing template. I'd start by making a marker for each corner (by setting absolute positions of, say, radiobuttons), get them to be positioned properly on paper and then work from there. But you're pretty much just going to have to tinker with it and move stuff until everything lines up.

Thank you, also can you think of a composite data structure that has a lookup of Order N?

>>60117990
a list. O(n) lookup is bad

>>60117990
a list has a worst case of O(n) => you have to traverse all n elements to get to your desired element.

an array has a constant lookup of O(1)

Its for a final problem lol, I have to come up with a composite data structure(2), to store information about a remodel of a home. And the composite must have a lookup of O(n) .

Java question. Say you want to set an instance variable in the constructor, is there a difference between using "instanceVar =x" or "this.instanceVar = x"?

The only difference I can think of is if you pass a parameter in the constructor which has the same name as inst

>>60117914
>>60117894
deletions and extensions are very fast compared to an array, traversal is fine (same order of magnitude as an array), but lookups are slow. looking up the nth element requires O(n) time, looking up the element in an array takes O(1) time.

most of the time you iterate though your arrays so you dont lose much by using a list unless you need random lookup

Wasn't sure whether to post this to /dpt/ or /sqt/. I'm learning JavaScript (inb4 ">JavaScript" + smug_asuka.png) and I feel extremely retarded, and I'm questioning how I've made it this far in life.

Pic related is the issue. I understand after some time exactly how it works. Using a for loop it sets a rudimentary "counter" called i to 0, checks each character in the string, and then the iterator i++ adds 1 to the count and loops until the if condition is met. When the condition is met it enters the second for loop

It's purpose is to search a string for a name. It's really basic and shitty since it doesn't check for the entire name, just the first capitalized letter then pushes it to an array called hits which then prints it to the console. So as long as you don't include a Capital letter the same your name starts with, it works fine. My question is this: Once the name has been pushed to the hits array it returns back to the first for loop and continues once again, but how does the first for loop's "counter", i, know where to pick up? According to my broken understanding it would just print infinitely in a loop. The only missing link is the iteratori++, what are the order of operations with this thing? When does it execute?

My whole understanding of this thing is fucked and I feel like a moron. Hopefully someone can understand my crazy ramblings.

Wrong thread. Untyped garbage is by definition not programming since it doesn't correspond to any logic.

>>60120070
>how does the first for loop's "counter", i, know where to pick up?
the second loop is still inside the first, and the i isn't changed in the second loop, so once it leaves it should have the same value and continue working as defined by the for (go until i<text.length, do i++)

>>60120070
try executing a for loop and find out

i think the ++ happens at the end of the for loop though, so if it caught E at i=50, after the nested if and for loop, i would increment to 51
