Fix misordered 'final static' modifiers.

Per the Java Language Specification (Java 17; https://docs.oracle.com/javase/specs/jls/se17/html/jls-8.html#jls-8.3.1), 'static' should appear before 'final'.

This is also consistent with source code analysis tools, like Checkstyle, rules: https://checkstyle.sourceforge.io/apidocs/com/puppycrawl/tools/checkstyle/checks/modifier/ModifierOrderCheck.html.
