Java枚举错误 - 返回类型reqiued

Question

我在java中创建了简单的枚举类.

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;
    }
}

但Netbeans说我:invalid method declaration; return type required, ilegal start of type在线element_sentence("b");.我不知道为什么？你能告诉我为什么吗？

Answer 1

该enum类型必须以逗号分隔:

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