I am writing a loop in java.

I have 2 integers dest & src. Please see question inline.

```
void test() {
    int[] arr = ..
    for (...) { //iterate over the array here.
        int src = arr[i];
        int dest= arr[j];

        if (dest != src) dest = src; //SHOULD I WRITE THIS?
            OR
        dest = src;                  //OR THIS?
        ..
    }
}

```
