clearing white space

[Chris Dancy]

got a quick question. Im trying to clear all the white space from a string. All other characters are ok, just the white space has to go. I've looked online and found nothing useful, I keep getting char cannot be dereferenced errors. here is the code i tried
public String clearWhiteSpace(String si){
char [] temp = si.toCharArray();
String s = "";
for(int i = 0;i < temp.length;i++){
if(!temp[i].equals(' '))
s += temp[i];
}
return s;
}

Im running out of ideas, if anyone can help, let me know.

thanks

Primitives dont have methods. To compare two primitives you use ==.

if(!temp[i] == ' ')

ahahaha. Stupid mistake on my part. I should have realized. thanks

You can also remove spaces from the string, like this...

public String clearWhiteSpace(String si){
  return si.replaceAll(" ", "");
}
