Removing All Commas from a String

[andy9507]

How can I remove all instances of a comma from a string?

There's an extremely easy and quick way, but I won't spell it out for you. Read through String (Java Platform SE 6) and see if you can find it!

I made my own method that I edited for my purpose from someone else, thank you for the link though!

import java.util.StringTokenizer;
public class CharacterRemover {
public String removeCharacter(String s, String removeChar) {
StringTokenizer st = new StringTokenizer(s,removeChar,false);
String t="";
while (st.hasMoreElements()) t += st.nextElement();
return t;
}
}

Or you can do that with one line:

String newStr = oldStr.replaceAll(",", "");

You could also use split, you should try to avoid string tokenizer.

Thanks guys, and yeah, I found that replaceAll method later, I'll be sure to use that next time to save me the trouble.

Just remember that replaceAll(...) takes a regex argument. For simple cases where you don't require the matching flexibility of a regular expression, use replace(...).
