Byte array with padding of null bytes at the end: how to efficiently copy to smaller byte array

Question

Have:

[46][111][36][11][101][55][87][30][122][75][66][32][49][55][67][77][88][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0]
         


        

Answer 1

why not try the static method array copy in the system class just give the source array src start position , destination array , destination start position and the length

        System.arraycopy(src, srcPos, dest, destPos, length);
        byte [] dest= new byte [6000];
        System.arraycopy(src, 0, dest, 0, 6000);
