Efficient though this is, it seems to mean that for "constants" that
you expect might change in a future version of a library you should
provide accessor methods and not a public static final field.
Otherwise, drop-in replacement of the older version with the newer
version in a deployed app's classpath might fail in bizarre ways. To
make sure newer versions of a library are binary-compatible with apps
that use the library, and not just source-compatible, requires not
changing the values of public static final fields.

So you'd want to use

public static final int MAX_FACTORIAL = 12; // 12! is less than
// Integer.MAX_VALUE; 13! is greater; and this will never change.

public static int getMaxTreeDepth () {
return 5;
// In later versions this might be increased to 6 or even 7.
}
