Array Copy for Any Objects

807606

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 ?

    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,
