无法创建枚举

Question

我正在尝试创建以下枚举，但 Eclipse 给出以下错误：

语法错误，插入“;”完成 ClassBodyDeclarations

代码：

public class SE {

    private enum Separator {
        COMMA(","),
        SEMICOLON(";"),
        COLON(":");

        private String separator;
    }

}

更新：

//still receiving the same error

public class ParameterParser {

private enum Separator {

    COMMA(","),
    SEMICOLON(";"),
    COLON(":");

    private String mSeparator;

    private Separator(String separator) {
        // TODO Auto-generated method stub
        this.mSeparator = separator;
    }

    public String getSeparator() {
        return this.mSeparator;
    }
}
}

Answer 1

添加构造函数

private Separator(String separator) {
    this.separator = separator;
}

Answer 2

您缺少枚举的构造函数！

private Separator (String s) {
    separator = s;
}

更新：

public class ParameterParser {

    private enum Separator {

        COMMA(","),
        SEMICOLON(";"),
        COLON(":");

        private String mSeparator;

        private Separator(String separator) {
            this.mSeparator = separator;
        }

        public String getSeparator() {
            return this.mSeparator;
        }
    }

    public static void main(String[] args) {
        Separator comma = Separator.COMMA;
        Separator semic = Separator.SEMICOLON;
        Separator colon = Separator.COLON;

        System.out.println(comma + ": " + comma.getSeparator());
        System.out.println(semic + ": " + semic.getSeparator());
        System.out.println(colon + ": " + colon.getSeparator());
    }
}

此代码编译良好并输出：

COMMA: ,
SEMICOLON: ;
COLON: :

因此，如果您对这段代码仍然有问题，那一定是 ist！您必须向我们提供更多信息（例如，可能已经定义了分隔符，ParameterParser 类中的更多代码等）
