Remote white space from string

Question

Hi I need a method which will remove the spaces in a string eg "Hello World" -> "HelloWorld"
I have the code below but it dosnt work for the obvious reason charAt() returns a char and im comparing to a string.
Can anyone offer any help? Thanks
          public void removeSpace(String s)
          {     int rs = s.length();
               String cat;
               for (int i=0;i<rs;i++) {
                    cat = s.charAt(i).toString();
                    if (cat==" ") {
                         s.replace(""," ");
          }

Hi,
You can't modify the contents of a String, you must create a new String, and use that one. Your code should be:
public String removeSpace(String s) {
    return s.replaceAll(" ", "");
}The returned string is the string without spaces.
