Question

当我试图给我以价值时,它给我这个错误:

不能将建筑状况适用于特定类型;

为什么发生这种情况,我如何确定这种情况?

我的法典是:

 public enum Status 
 { 
     STATUS_OPEN(0),  
     STATUS_STARTED(1),  
     STATUS_INPROGRESS(2),  
     STATUS_ONHOLD(3),  
     STATUS_COMPLETED(4),  
     STATUS_CLOSED(5);  

 }

我用笔记和“JDK”迅速使用,但此时我不想使用净豆或ec。

I was following this site: link

我ve了周围,我无法真正找到为什么出现这一问题,或如何通过寻找错误来加以纠正。

Answer 1

You need to add a constructor to the enum.

public enum Status {
   STATUS_OPEN(0),  
   STATUS_STARTED(1),  
   STATUS_INPROGRESS(2),  
   STATUS_ONHOLD(3),  
   STATUS_COMPLETED(4),
   STATUS_CLOSED(5);

   private final int number;
   Status(int number) { 
       this.number = number;
   }

   public int getMagicNumber() { return number; } 
}

This ll fix your syntax problems, but what are you hoping to achieve with the number? Enums are often used instead of the need for numbers at all.

public enum Status 
 { 
        STATUS_OPEN(0),  
        STATUS_STARTED(1),  
        STATUS_INPROGRESS(2),  
        STATUS_ONHOLD(3),  
        STATUS_COMPLETED(4),  
        STATUS_CLOSED(5); 

       private int status;

       private Status(int status){
        this.status = status;
       }

     public int getStatus(){
       return this.status;
      } 
 }
