| While the Java programming language requires that `public` top-level classes are |
| declared in a source file matching their name (e.g.: `Foo.java` for `public |
| class Foo {}`, it is possible to declare a non-public top-level class in a file |
| with a different name (e.g.: `Bar.java` for `class Foo {}`). |
| |
| The Google Java Style Guide ยง2.1 states, "The source file name consists of the |
| case-sensitive name of the top-level class it contains, plus the .java |
| extension." |
| |
| ## Suppression |
| |
| Since `@SuppressWarnings` cannot be applied to package declarations, this |
| warning can be suppressed by annotating any top-level class in the compilation |
| unit with `@SuppressWarnings("ClassName")`. |
