Why does the array give the wrong result?

Question

Java

public class Main {
    static void bar() {
        int[] nums = {1, 2, 3};
        for ( int x = 0; x < nums.length; x++ ) {
            x += nums[x];
        System.out.println(x);
        }
    }
    public static void main(String[] args) {
            Main.bar();
        }}

When compiled, the result is:

1
5

I can’t understand why, because first 1 is written to the x variable, then it is displayed on the screen, then 2 should be added and 3 should be displayed in the console, and 5 is displayed immediately.

Answer 1

First, the array does not produce anything anywhere.
Secondly, you use the same variable to iterate over the array and for the accumulator. Use different ones.
