| `final` fields initialized with a literal can elide a per-instance reference by |
| adding the `static` keyword. Since the field is `final` it is unmodifiable and |
| since its initializer is a literal the value is immutable and thus sharing a |
| per-class field is safe. This also allows a simpler constant load bytecode |
| instead of a field lookup. |
| |
| That is, prefer this: |
| |
| ```java |
| static final String string = "string"; |
| static final int number = 42; |
| ``` |
| |
| Not this: |
| |
| ```java |
| final String string = "string"; |
| final int number = 42; |
| ``` |
