you're on the right track.
In the original code:
System.out.println(lo);
while (hi < 50) {
System.out.println(hi); //*** output
hi = lo + hi; // new hi
So you are outputting the hi variable
In your new code:
lo = hi - lo;
array[i++] = hi; // *** adding to array
array[i++] = lo; // *** adding to array
}
so you are 'outputting' both the hi and lo variables
