Iterate an Array

Hello Woofers!

I am here, once again, to teach you woof to iterate an Array in Java! I'm serious, I didn't know, until today, Woof to iterate this thing!

Well, now I know, and the ingredients for this recipe are simple:

- create an array with a name ar (eg ar from array) which will have 8 array elements (eg 1,2,3,4,5,6,7,8)

- two extra integers, one for my loop counter and one for the assignment of each element of our array.

My code is below:

// Java program to iterate over an array 
public static void main(String args[]) {
  int ar[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; 
  int i, x; 

  // iterating over an array 
  for (i = 0; i < ar.length; i++) { 

    // accessing each element of array 
    x = ar[i]; 
    System.out.print(x + ", "); 
  } 
}

* the +", " connects a String to our integer. With this addition, you will have spaces and commas and anything other info you want between your array elements.
** If you want each element to be printed in another line, you can simply use the System.out.println(); 🙂

When you compile the code (I use Netbeans in my iWoof Pro), the result will be this:

1, 2, 3, 4, 5, 6, 7, 8

Well Done!
You just created and iterated an array!

Arrays are very important for both simple and complicated projects, and especially for game development!
