public class NoEnumTrailingCommaCheck extends AbstractCheck
Checks that enum definition does not contain a trailing comma. Rationale: JLS allows trailing commas in arrays and enumerations, but does not allow them in other locations. To unify the coding style, the use of trailing commas should be prohibited.enum Foo1 { FOO, BAR; }
The check demands that there should not be any comma after last constant in enum definition.
enum Foo1 { FOO, BAR, //violation }
