Byte array with padding of null bytes at the end: how to efficiently copy to smaller byte array
Here is my try:
static byte[] trim(byte[] bytes){ int i = bytes.length - 1; while (i >= 0 && bytes[i] == 0) { --i; } return Arrays.copyOf(bytes, i + 1);}public static void main(String[] args){ byte[] bytes = { 0, 1, 2, 0, 3, 4, 5, 0, 6, 0, 0, 7, 8, 9, 10, 0, 0, 0, 0 }; byte[] trimmed = trim(bytes); return;}
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);
