I'm trying to convert a String of characters that has spaces in it to a BigInteger...and I'm failing. Any help would be greatly appreciated.

Examples please. And your code.

Well, is there a function to remove all spaces from a String? I believe trim() only removes spaces from the beginning and end of the String.

Or am I gonna have to right a loop or something to do it?

Also, I guess I need to get the characters in the String into digits. Is getBytes going to be the best way to do this?

EDIT: Here's the String:

String message = "The quick brown fox jumps over the lazy dog.";

I'm not necessarily looking for the code. Even if someone could just let me know which functions or type of code (e.g. loop, etc.) would be the best way to do this, I could take it from there.

Alright. I actually just ended up using String.getBytes() to convert it into bytes, and then was able to declare a BigInteger with the value from the bytes.

anyway to remove all spaces you can use String.replaceAll()

An example that removes all whitespaces from the string:

        String s = "The quick brown fox jumps over the lazy dog.";
        s = s.replaceAll("\\s", "");
        System.out.println(s); 

Results: Thequickbrownfoxjumpsoverthelazydog.

s.replaceAll() takes regex as an argument, so if you are not familiar with them, you should look them up.

[eafkuor]

this should work as well:

s = s.replaceAll(" ", "");

Thanks for the tip!
