more questions,
I've completed several lessons, how do I submit them to the "nitpickers"

do I post my work to the forum ?

thank you, I know the technique now I know the name

what exactly is meant by a java factory ?

premature response. there was another java.exe in c:\winnt\system32 ,a directory that appears prior to the 1.4 directry in the path statement.
I renamed the system32 java.exe and everything is kooool.
is this java.exe important and why all of a sudden the problem. is Bill G. slipping secret files into my directory structures.
Thanks

no luck

easy answer - Point p will never equal Point q,
either equals() or ==
Point a = new Point();
Point b = a;
if (a.equals(b)) is true because they both reference the same object, the default requirement for the equals method.
I posted a answer for possible solution to the equals problem in the intermediate forum

same thought, first action performed. results same problem. the reinstall first removed, than I reinstalled. really hard to imagine why javac path resolves and java path does not resolves

the default behavior, the equals method of object class, equates to true if both references point to the same object.
http://java.sun.com/products/jdk/1.1/docs/api/java.lang.Object.html
The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).
You can override the equals method within your class by using the reference passed to the equals
method
equals(Point p){
if ((this.x == p.x) && (this.y == p.x)){
return true;
}
else {return false;}
}
overriding the toString method
you can return whatever string or string concatenation you beleive to represent the objec

I'm unable to execute the java.exe from any directory except bin. javac works great from any directory, and java.exe does if I specify the entire path followed by the class name.
here is my path statement:
C:\WINNT>path
PATH=C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\PROGRA~1\ULTRAE~1;C:\j2sdk1.4.0\bin;
here is my class path:
classpath=.;c:\j2sdk1.4.0\lib;
what am I missing ?

C:\WINNT>java -version
