Java help

[ultimamax]

I want to make a prime number method (it identifies all prime numbers btwn 0 and the parameter)
But I forgot how to set it up
How do I write up a method?
How do I set up the main method majigger?

i forgot what prime numbers are, lol.

a number that can only be divided by 1 and itself without a remainder. e.g 7, 13, 17

[Elecro]

so basically odd numbers?

[ultimamax]

nope.
15 can be divided by 5 and 3 for example.

OT: I don't know.

how

what the f

OT: I don't know.

okay seriously how did they not teach you this stuff in third grade


OT: i did this for my IT class not too long ago, something like this:

static boolean isPrime(int num) {
   for (int n2 = 2; n2 < num - 1; n2++) {
      if (n1%n2 == 0){
         return false;
      }
   }
   return true;
}

it checks every number except 1 and the number given and sees if the remainder of the division of the two numbers is 0. if it finds any number that is evenly divisible without a remainder, it returns false, otherwise returns true.

this might not work though, i'd need to open the project up in eclipse or something to be sure of its functionality.

i did learn in 4th grade, and that was like 5 years ago.

uh, i didn't want an answer, i just wanted to know how to preface my program. (e.g setting up the main method, all those import shenanigans)

[Kingdaro]

oh, i think i see what you're saying


class SomeGayClass {
   static String someGayMethod() {
      return "huehuehueheuheuehu";
   }

   public static void main(String[] args) {
      System.out.println(someGayMethod());
   }
}


like this?

and for something like this, you don't really need to import much, if anything at all.

[lolz??]

so, your in high school but don't know what a prime number is?

yes like that. thanks.

in high school next year.

Code: [Select]

class wooble {
public static void main(String[] args) {
System.out.println("Open the door get on the floor")
}
}
is a much shorter way

[Kingdaro]

i was only demonstrating how methods would work. i could've just done this

class SomeGayClass {
   public static void main(String[] args) {
      System.out.println("huehuehueheuheuehu");
   }
}
