Java简单的String 大小端转换

  public static void main(String[] args) {
        String str = "00001234567890";
        byte[] bytes = str.getBytes(StandardCharsets.UTF_8);
        byte temporary;
        for (int i = 0; i < bytes.length/2; i+=2) {
            temporary=bytes[bytes.length-i-2];
            bytes[bytes.length-i-2]=bytes[i];
            bytes[i]=temporary;

            temporary=bytes[bytes.length-i-1];
            bytes[bytes.length-i-1]=bytes[i+1];
            bytes[i+1]=temporary;
        }
        System.out.println(new String(bytes));
    }
