Is there anybody who knows I to become a Java trainer (certified?) ?

Thanks guy, when I will found the theory I a will post it!

I passed the exam with success today.
JavaRanch made the difference for me bettween success and failing since I was studying alone.
I will say that now that I have some base (after all I'm a SCPJ2 now) Java ranch still a good place to improve and challenge what I know.
Thanks to all

I have the list of keyword published by sun at
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/_keywords.html
and it is there. (added with Java 2)
My guest is that your JDK1.2 is not the last release or that you don't use it correctly.

In the code below what triggers my curiosity and my understanding is that the line tagged with Tag: produces q.y = 7 ?
Anyone can direct my research on this ?
<pre>
class Shape {
int x=7, y=7;
int getY() {
System.out.println("Shape " + y);
return y;
}
}
class SubShape extends Shape {
int x=5, y=5;
int getY() {
System.out.println("SubShape " + y);
return y;
}
}
class CastObj extends Object {
public static void main(String args[]) {
Shape p = new Shape();
System.out.println("p.y = " + p.y + " p.getY() = "+ p.getY());
Shape q = new SubShape();
System.out.println("q.y = " + q.y + " q.getY() = "+ q.getY());

Tag:System.out.println("p.y = " + p.y + " q.y = "+ q.y);
System.out.println("p.getY() =" + p.getY() + " q.gety() " + q.getY());
}
}
// Result printed out
//
// Shape 7
// p.y = 7 p.getY() = 7
// SubShape 5
// q.y = 7 q.getY() = 5
// p.y = 7 q.y = 7
// Shape 7
// SubShape 5
// p.getY() =7 q.gety() 5

//

Thanks I get it.
I've try this way to get it.
System.out.println( sb1.toString().equals(sb2.toString()));

Again guys, out there taking care of those questions let me say that I appreciate a lot.

It seems like I have missed a point in my lecture somewhere and I have difficulty to understand the following test I have done with the equal method.
Let see my code:
Line 1 StringBuffer sb1 = new StringBuffer("JAVA");
Line 2 StringBuffer sb2 = new StringBuffer("JAVA");
Line 3 System.out.println( sb1.equals(sb2)); //false

Line 4 String s1 = new String("JAVA");
Line 5 String s2 = new String("JAVA");
Line 6 System.out.println( s1.equals(s2)); //true
What I was expecting the same result in line 3 and 6. Could you give me an advice of where I can go for fixing my inquiry.
Thanks

Hummmm, I'm not able to put at work this new version of ThinkPad .
Any suggestion is welcome.
