Hi,
I have the following string and I would like to replace all the spaces and commas in this string with some characters.

Please see the example below:

Input string:

12345, 234567 3456789

Open in new window


Expected output string:

-c 12345 -xyz\r\n-c 234567 -xyz\r\n-c 3456789 -xyz

Open in new window


how can I do it in Java?

I would do it in two stages

a. tokenize the string
b. place the tokens in a new one

a. has already been answered elsewhere

b. (assuming that's a command)

String command = String.format("-c %s -xyz\\r\\n-c %s -xyz\\r\\n-c %s -xyz", tokens[0], tokens[1], tokens[2]);

Sorry, I couldn't understand it. Can you please send me code with the tokenizing part?

And example that I sent you has three numbers in it but there can be any number of numbers in the input string.

Example2:

12345, 234567 3456789, 345672 4532344566,4366, 46665467

That's already been answered by kaufmed

And example that I sent you has three numbers in it but there can be any number of numbers in the input string.
And the same prefix goes before every number?

@CEHJ: The code you sent me is only for 3 numbers. If you can send me the whole code (inlcuding kaufmed's answer). that would help me better.

Thanks,

oh, sorry, I didn't read your last line as a question.

And yes, the same prefix goes before every number.

ok. This is what I have with  Kaufmed's code in it:
            String ListNumbers = listNum.replaceAll("[ ,]+", "\r\n-c ");
            populatechangelist("-c " + ListNumbers + "\r\n");

Open in new window


The code above only add "-c " in the beginning of each number by replacing space or comma in between the numbers.

However, I also need to add "-xyz" after any number. And I cannot do it.

Do you have any idea?

This "\r\n" - are you intending that to be a linefeed?

Try

    public static String getParameters(String s) {
        final String LINEFEED = System.getProperty("line.separator");
        StringBuilder result = new StringBuilder();
        String[] atoms = s.split("[ ,]+");
        String sep = "";

        for (String atom : atoms) {
            result.append(String.format("%s-c %s -xyz", sep, atom));
            sep = LINEFEED;
        }

        return result.toString();
    }
