What would be the difference between Java 1.4.2's implementation of replace, and Apache 2.3's implementation? Is there a performance gain one over another? Java 1.4.2 replace Apache 2.3 replace The String.replace() method you linked to takes two char values, so it only ever replaces on character with another (possibly multiple times, 'though). The StringUtils.replace() method on the other hand takes String values as the search string and replacement, so it can replace longer substrings. The comparable method in Java would be replaceAll() . replaceAll() is likely to be slower than the

This question already has an answer here: Join comma if not empty or null 8 answers In Java 8 I have some number of String values and I want to end up with a comma delimited list of valid values. If a String is null or empty I want to ignore it. I know this seems common and is a lot like this old question ; however, that discussion does not address nulls AND spaces (I also don't like the accepted answer).

I have a String and I want to extract the (only) sequence of digits in the string. Example: helloThisIsA1234Sample. I want the 1234 It's a given that the sequence of digits will occur only once within the string but not in the same position. (for those who will ask, I have a server name and need to extract a specific number within it) I would like to use the StringUtils class from Apache commomns. Thanks! Use this code numberOnly will contain your desired output. String str="sdfvsdf68fsdfsf8999fsdf09"; String numberOnly= str.replaceAll("[^0-9]", ""); Michael Bavin I always like using Guava
