    Default Stuck on 12 node star assignment

    Hi I am doing an assignment in my Java class and I need to connect the nodes to make a 12 pointed star. I have already drawn out the star and figured out which nodes to connect together. The only thing I cannot get is to show all of the nodes in the order they connect. I can only get the first 3 nodes to show up. I need it to wrap around and basically keep adding 5 to the last node until all numbers 0-11 are used. Any suggestions on what I can do to make that happen? I feel like it is one little bit of code I need to put in but I cannot figure out what it is.

    public class StarWinding {
    	public static void main(String[] args) {
    		for (int i = 0 ; i < 12; i+=5) {
    			System.out.print(i + " ");
     
    			}
    	}
    }

    And the out put so far is: 0 5 10
    I need it to be: 0 5 10 3 8 1 6 11 4 9 2 7

    What is the logic for generating that sequence of numbers?

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    Because I have a 12 pointed star and each point is numbered. You have to create a 12 pointed star by connecting these numbered points together. If you just connect the points in order you get a 12 sided-gram and not a star. I need the code to wrap back to zero and keep adding by 5. Example: 10 + 5 = 3 because 11, 0, 1, 2, 3. the highest it goes is 11 and then needs to start over at 0 and keep counting.

    When you add 5 to 10 you get 15 which is greater than 12 and your loop exits. You will need to rethink your design. Maybe a while loop would be better. To wrap your values back around to 0 you can use a circular counting pattern or simply subtract 12 when value is greater than 12.

    I understand what you are saying Junky... I just do not know how to perform that operation in Java.

    I cannot just subtract 12 it will not work out. I don't know how to wrap my values back to 0. that is my whole problem.

    Perhaps you need two variables: one to count to 12 and one to hold the value to print.

    i do not know how to make one to hold the value to print
    I'm surprised that you don't know how to define a variable and give it an initial value. An example:
      int valToPrint = 0;   // define a variable to hold the value to print
