I have just come across the following:
static final int ASCENDING = 2;
static final int DESCENDING = 4;
This raised the following question: Why are the variables ASCENDING and DESCENDING in upper case?
I thought variables were lower case and a Class began with a capital letter.
Thanking you in advance.

If you define so called constants (final and meybe static) the code conventions tell you to write them in capitals only.
If multiple words then seperate them with _

Hi,
It is just a naming convention in Java to name all "final static" (constant) variables defined as part of class defination in ALL CAPS.

This is just a widely used convention for constants. Notice the final static modifiers.
Other examples are Math.E, Math.PI, Color.RED, Color.BLACK (the Color class also defines lowercase versions Color.red for example).
