Class NoEnumTrailingCommaCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    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
 }
