in the Java API guide (http://java.sun.com/j2se/1.5.0/docs/api/java/io/

has the current user directory.
How do I access the value in this property?
Alternately, is there another way I can establish a base directory
such that, in a subdirectory of my package/jar, I can store data for
the application to read?
Eg. if my application is running in C:x\y\z, I'd like to have a
directory whose fully-qualified name is C:x\y\z\data. If the
application is transported and later runs on D:\a\b\c\, I'd like that
directory to resolve to D:\a\b\c\data.
Thanks.
Mike,
user.dir : is where you program is starting from
to get the value, just write this line
String basedir = System.getProperty("user.dir");
in your case, basedir will be "D:\a\b\c"
you need to do something like: basedir + "\data" to get an absolute
path.
To learn more, just run this small program.
/** start **/
import java.util.Enumeration;
import java.util.Properties;
public class Test {
public static void main(String[] args) {
Properties p = System.getProperties();
Enumeration es = p.elements();
while (es.hasMoreElements())
System.out.println(es.nextElement());
}
}
/** end **/
