arrays questions:

int arr[] = new array [10];

for (x = 0 ; x < array.length ; ++x)
   arr[x] = x * 3;

//pos: 0  1  2  3  4  5  6  7   8  9
//val: 0  3  6  9 12 15 18 21  24 27 

for (x = 3 ; x < array.length ; x = x + 3)
   arr[x] = arr[x-1] + arr[x-2];

//pos: 0  1  2  3  4  5  6  7  8  9
//val: 0  3  6  9 12 15 27 21 24 45
