Java enum giving an error?

Question

When I try to give a value to my enum, it gives me this error:

constructor status in enum status cannot be applied to given types; STATUS_OPEN(0),

Why is this happening and how do I fix it?

Here is my code thus far:

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

 }

I'm using notepad and the JDK via command prompt - I don't want to use netbeans or eclipse at the moment.

I was following this site: link

I've googled around and I couldn't really find why this issue is occurring or how to fix it by searching for the error.

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.

Answer 2

you need to declare the status instance variable and constructor. like this

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;
      } 
 }
