Java enum error - return type reqiued

Question

I created simple enum class in java.

public enum XmlElementsInput {

    element_sentenceInput("a");
    element_sentence("b");

     private final String elementName;

    private XmlElementsInput(String name) {
        this.elementName = name;
    }
    public String getElementName() {
        return elementName;
    }
}

But Netbeans say me: invalid method declaration; return type required, ilegal start of type on line element_sentence("b");. I dont know why? Can you tell me why?

Answer 1

The enum types must separated by comma:

element_sentenceInput("a"),
element_sentence("b");
