'public static final' variables are constant.

The naming convention for static final variables is to have them in upper case and separate two words with an underscore. For example:

static final int NUMBER_OF_MONTHS = 12;
static final float PI = (float22 7;

If you want to make a static final variable accessible from outside the class, you can make it public too:

public static final int NUMBER_OF_MONTHS = 12;
public static final float PI = (float22 7;
