Alternate names: TopLevel

The problem

The Google Java Style Guide ยง3.4.1 requires each source file to contain exactly one top-level class.

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("MultipleTopLevelClasses").
