So isn't thats what exactly David has said in his post?

int x = getHeight(k2.left);

the compiler assumes that you're referring to the current object. It is as if you wrote:

int x = this.getHeight(k2.left);

boils down to

The code

int x = getHeight(k2.left);

is same as if you wrote

int x = this.getHeight(k2.left);

:-)

There should be no difference (because the default instance of the method called is the one that comes with the current instance of the class (i.e. this one).

You're quite right, of course. Which just goes to show two things:
1) Just because you've "known" something for years, doesn't make it true.
2) Never publish even the simplest code without testing it first.
3) Name shadowing is evil.
4) Don't count your conclusions before you've made them.

Thank for the help again!
I have another problem now.
How do I use sort?

sort
public static void sort(Object[] a, int fromIndex, int toIndex, Comparator c)

what is comparator?
I write
String[] array = { "abc", "def" )
sort(array, 0, 44);
which will not work!
How do I use it? Thanks!

For a utility that suggests/generates sample code for converting Java primative types, check out theConversion Amenuensis at http://mindprod.com/amanuenses.html.
