why does i % 2 == 0 print odd numbers and i % 2 == 1 print even numbers in my for loops? Am I thinking of modulus the wrong way?

//Array: 
        int[] nums = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10}
        nums ==> int[10] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

//for-loop that prints odd numbers: Shouldn’t i % 2 == o print even numbers?

jshell> for(int i = 0; i < nums.length; i++){
   ...>     if(i % 2 == 0){  // even numbers?
   ...>         System.out.println(nums[i]);
   ...>     }
   ...> }

>Solution :

Arrays are zero-indexed in Java (and most languages derived from C). This means we start counting from 0; an array with 10 elements has indices 0, 1, …, 9.

So nums[0] is the 1st element of your array, i.e. 1. When the index i is 0, i % 2 == 0 will be true (because i is an even number). So you’ll print an odd number (nums[i]) when i is even.
