| 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")`. |
