'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 = (float) 22 / 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 = (float) 22 / 7;
