I have a java string with " " from a text file the program accesses with a Buffered Reader object. I have tried string.replaceAll(" ","") and it doesn't seem to work.
Any ideas?
cleaned = cleaned.replace(" "," ");

The same way you mentioned:
String cleaned = s.replace(" "," ");
It works for me.

@Stephen: I was reluctant to post the entire quote. [It's quite a topic](http://wiki.lspace.org/wiki/Multiple_exclamation_marks)

@Manuel: never mind me, just a little joke. Read the link in my previous comment, if you want to know more.

@Joachim. I understand that I must be a little bit crazy with all the multiple exclamation marks I am using, isn't it ???

A:
Strings are immutable so You need to do
string = string.replaceAll(" ","")

Take back that -1; if you look at the `replaceAll` example posted in the original post, he's is not clearly already doing that.

A:
String.replace(char, char) takes char inputs (or CharSequence inputs)
String.replaceAll(String, String) takes String inputs
For example:
String origStr = "bat";
String newStr = str.replace.('a', 'i');
// Now:
// origStr = "bat"
// newStr = "bit"The key point is that the return value contains the new edited String. The original String variable that invokes replace()/replaceAll() doesn't have its contents changed.
For example:
String origStr = "how are you?";
String newStr = origStr.replaceAll(" "," ");
String anotherStr = origStr.replaceAll(" ","");
// origStr = "how are you?"
// newStr = "how are you?"
// anotherStr = howareyou?"

Note: there's a bug in S.O. that's now rendering my links at the bottom correctly.

Links fixed; they had spaces that needed to be replaced with `%20`. Usually happens when you copy from your browser after it cleans up the URL to "look nice" instead of copying the raw URL.

A:
the string in java are immutable... you have to do
String newStr = cleaned.replaceAll(" ", "");
This works correclty.

If you notice, the OP has the replaceAll value being put into a variable - overwriting the original value in the variable.

A:
Why? It must be XML or HTML, i.e. a markup language, so why are you removing the author's markup?
