How to remove all spaces from a Java string

java Add comments

Java 1.5 added a replace() method that could be used to replace all occurrences of a string wiuth another string

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

Prior to 1.5 you can use a regular expression with the replaceAll() method to achieve that.

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

// Or to replace all whitespace

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

Let us know if you need a different solution.
