Strings and things...

Hi there,

I haven't visited the forums in quite some time!
How is everyone :afrog:

Anywho, i've been taking a computer science course this semester and we've been doing java(no fancy ide's..just Textpad ...used to use bluejay)

We have done a few simple games, frogger, etc.. as well as a console app with arrays to sort some tax calculations.

We are currently working on a console app to take a textfile and give the user options to do 1-9 different things... the option i am on at the moment is a Trimming method (i was trying to come up with a simple way to search through the contents stored in a string 's' for different characters such as (! , ' " -) and remove them. Heres what i wrote up today and of course it doesn't work but i'm wondering if trying to get a stringbuffer to work is the right thing or not....or should i use arrays and substrings to accomplish this, i also need to remove whitespace from the strings.

here goes my messy code:

Code:

---

public static String StringTrimWord(String s)
 {
  String rand = ("");
  StringBuffer StringStuff = new StringBuffer(s);

  int mySearch = StringStuff.indexOf("!");
  StringStuff.setCharAt(mySearch, rand);
  return s;
 }

---

of course i'm calling stringtrimword(s); in my main method before i do system.outprint. I believe i was receiving an error with this code at 'rand' during my setCharAt call.

That is just an example of the idea i had to accomplish this easily.
Thanks for any input you may have!

use:

Code:

---

StringStuff.insert(mySearch,rand);

---

instead of :

Code:

---

StringStuff.setCharAt(mySearch, rand);

---

By the way, there is a method in java.lang.String called trim(); it Returns a copy of the string, with leading and trailing whitespace omitted.

Thanks for the reply :)

I guess i should have looked up stringbuffer on the sun site before posting :o

Never saw insert lol

Hopefully it will work though, i don't have my code on this pc so i can't test it right now unless i make a little sample project...but i can wait :)

Anywho, this will be great if it does work - the methods my professor was recommending involved alot more code and dealing with arrays and subarrays being held in temp strings etc.... my code will be faster i think.

Anymore suggestions would be nice; maybe a faster way? or something i don't know about..or any links to sites with some reading on strings and file i/o would be appreciated.
