Array Copy

[davidlan]

<p.4-30, Java SE7>
Shallow Copy (並未實際 copy Array 內的每個物件)
1.
int[] scores1 = {...};
int[] scores2 = scores1;
2.
System.arraycopy(scores1,0,scores2,0, scores1.length);
3.
int[] scores2 = Arrays.copyOf(scores1, length); (length 超過 scores1.length 時，預設值為0)

Deep Copy (得自行實作，每個物件都得 copy)
