Now it is right. This was solved. Thanks.

only with no spaces. Thanks

Hi Norm
Thank you
It was - encrypt but should have been -encrypt, so a blank space was the problem.

Now I need to take out all the blank spaces of s. Any idea of how could I do that?

An example is below:



public class CaesarBox {

public static void main(String[] args) {
// CaesarsBox <-encrypt|-decrypt>

if(args[0].equals("-encrypt")){

public static void main(String[] args) {
// CaesarsBox <-encrypt|-decrypt>

if(args[0].equals("-encrypt")){
System.out.println(encrypt(args[1]));
}
else...

String [] mess = args[1].toLowerCase(args[1]);

Error:

args cannot be resolved to a variable

--- Update ---

Sorry just saw your reply now.

args(0) is the input argument set by the user(text message)

--- Update ---

Sorry, args[0]

So it would be

String [] mess = args[0].toLowerCase(args[0]);

args(0) = "The sky is beautiful today"

I will encrypt this message later in a Caesar Box.

The error message is:

The method args(int) is undefined for the type CaesarBox

*ps: CaesarBox is...

Yes, sorry.

So I don't need to convert it to an array.

I need to change args(0) from "The sky is beautiful today" to theskyisbeautifultoday

I have tried

String [] mess =...

Thanks for your reply
Actually, args(0) = "The sky is beautiful today"
So args(0) is one string
args(0) is set by the user and could be any other text message

I need to convert a text message from the command line into an array of letters.

args(0) is a string, for example "The sky is beautiful today". And I want it to become theskyisbeautifultoday
