我试图声明很多枚举，但是由于某种原因，其中一个是错误的，我真的不明白为什么。

我的声明：

    public enum MainObjectType {

}

错误说：语法错误，插入}来完成类体

枚举的元素需要用逗号分隔，并且您设置每个元素的值的语法不正确。

首先，您需要使用正确的语法来设置值。语法应该是EnumValue(value)您有一个私有构造函数的地方，该构造函数采用您将枚举元素设置为的类型。在这种情况下，您private MainObjectType(int value)的枚举中需要一个构造函数。您还需要用逗号分隔每个元素。

查看枚举类型的 Java 教程以获取一些示例。

您的语法无效。你可以写：

public enum MainObjectType  {
    StationEntrance,
    StationConcourse_Hall,
    StationPlatform,
    StationStairs,
    // ...
    NPM_MajorIssues;        
}

但这会丢失编号。或者您可以使用以下语法提供一个数字：

public enum MainObjectType  {
    StationEntrance(1),
    StationConcourse_Hall(2),
    StationPlatform(3),
    StationStairs(4),
    // ...
    NPM_MajorIssues(3564);        

    private final int id;
    private MainObjectType(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }
}

然后你可以写：

int id = MainObjectType.StationEntrance.getId(); //id = 1
