Removing the first 16 bytes from a byte array

Question

In Java, how do I take a byte[] array and remove the first 16 bytes from the array? I know I might have to do this by copying the array into a new array. Any examples or hel

Answer 1

System.arraycopy() also can do that:

public static byte[] truncate(byte[] bytes, int srcPos, int newLength) {
    if (bytes.length < newLength) {
        return bytes;
    } else {
        byte[] truncated = new byte[newLength];
        System.arraycopy(bytes, srcPos, truncated, 0, newLength);
        return truncated;
    }
}
