SubString problem

ThaEagle

Hi. I need to use SubString to pick up parts of the text in a String.

How do I use subString?
I have downloaded the new files from http://tech.groups.yahoo.com/group/JavelinCode/files/Javelin Stamp IDE/lib/java/lang/
and saved them in "C:\Programfiler\Parallax Inc\Javelin Stamp IDE\lib\java\lang\"
("c:\Programfiler" equals to "c:\program files\")

But it still not work. have I imported wrong packages?


import stamp.core.*;
import java.lang.String;
import java.lang.StringBuffer;

String wps = "3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W";


// all of theese is gives me error on the part SubString(No method named SubString was found in type java/lang/String)(No field named StringBuffer was found in type java/lang/String) :
wp1la = ((((Long.parseLong(wps.StringBuffer.subString(4,7))*60)+Long.parseLong(wps.subString(4,7)))*10000)+Long.parseLong(wps.substring(4,7)));
wp1lo = ((((Long.parseLong(wps.StringBuffer.SubString(4,7))*60)+Long.parseLong(wps.SubString(4,7)))*10000)+Long.parseLong(wps.substring(4,7)));

The following

import stamp.core.*;
public class test {
  String wps = "3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W";
  static void main() {
  }
}

compiles fine for me.
There is no SubString method for String.
There is a indexOf(String s) method that returns the index when s is part of the string.

· int p = wps.indexOf(".3416W") should yield 15.

StringBuffer has a subString() method (not SubString).
You can use
· StringBuffer wps = new StringBuffer("3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W-3723.2475N12158.3416W");

and use wps.subString()

Thank you. My GPSproject is almost done now. Just a few bugs left.
