Hi all,
I wrote a function which is used to concat two Arrays. HOwever, I need to specifiy the data type in the function, it's not OO and absolutely not dynamic, how can I improve it ?
Thanks for helping me

I wrote a function which is used to concat two Arrays. HOwever, I need to specifiy the data type in the function, it's not OO and absolutely not dynamic, how can I improve it ?
public static Object concatDualArray(Object[] A, Object[] B) { StandingData[] C= new StandingData[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; }I summon that function from my core function, which is
StandingData[] trancheStatusListData = (StandingData[]) TrancheUtility.concatDualArray((Object[])trancheApprovedStatusListData, (Object[])trancheApprovalStatusListData);Is there any reflection method can let my function looks more OO ?
Thanks for helping me

Personally I wouldn't go for the array approach in the first place, because
their type can not be parameterized; e.g. the following is simply not
possible, no matter how cute it looks:public static<T> T[] concatDualArray(T[] A, T[] B) { T[] C= new T[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; }
Arrays are very non-OO; why not stick to a List<T> instead?
kind regards,
Jos
