Java注释将字段设置为其名称

Question

Is there any Java annotation that sets a field value to it's name, for example:

public interface Protocol {
    @Whatever String START; // Here @Whatever annotation would set START to "START" in any static string field.
}

Answer 1

No, But you can use enum class.

public enum Protocol  {
   START,
   END
}

And then when you will write:

System.out.println(Protocol.START);

You will get "START"
