But how organize constants when are more than one? With respect to this answer and this one, it seems the best way to organize them is using Enum:

I use eclipse and some times I have texts that appears in different places, like comments, messages... For example if I have a custom Exception, probably class doc, messages that passes as parameter to its constructor and documents of each method that throw exception will have the same phrases and terms. If I copy/paste phrase, maintenance of documents will be hard (it needs finding and updating all repeats on each edit).

 /**
  * comment for CONSTANT
  */
public static final String CONSTANT = "comment for CONSTANT";

public enum Meta {
    /**
     * comment for CONSTANT
     */
    CONSTANT("comment for CONSTANT");

    private String text;

    Meta(String text) {
        this.text = text;
    }

    public String getText() {
        return this.text;
    }

}

Some times I have texts that appears in different places, like comments, messages... For example if I have a custom Exception, probably class doc, messages that passes as parameter to its constructor will have the same phrases (here This exception throws under situation1):

/**
 * This exception throws under situation1 ...
 *
 */
public class SomeException extends Exception {

    public static class Builder{
        String message = "This exception throws under situation1. So ... ";

        public Builder(String message) {
            this.message = this.message + "\r\n" + message;
        }
        public SomeException build(){
            return new SomeException(this);
            
        }
    }
    
    private SomeException(String detailMessage) {
        super(detailMessage);
    }

    public SomeException(Builder builder) {
        this(builder.message);
    }
}

And also documents of each method that throw exception will have the same phrase:

/**
 * @throws SomeException
 *             This exception throws under situation1 ...
 */
private void test() throws SomeException {
    throw new SomeException.Builder("message").build();
}

If I copy/paste phrase, maintenance of documents will be hard (it needs finding and updating all repeats on each edit).

 /**
  * exception throws under situation1
  */
public static final String CONSTANT = "exception throws under situation1";

public enum Meta {
    /**
     * exception throws under situation1
     */
    CONSTANT("exception throws under situation1");

    private String text;

    Meta(String text) {
        this.text = text;
    }

    public String getText() {
        return this.text;
    }

}
