Usually I have text 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). 

To solve this, I can use a constant string that its value and its comment are those repetitive terms

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

and reference to it:

		/**
		 * {@link MyClass#CONSTANT}
		 */
		String message = MyClass.CONSTANT;

But how organize constants when are more than one? With respect to [this answer][1] and [this one][2], it seems the best way to organize them is using `enum`:

    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;
    	}
    
    }

But is there a better way than this? Especially it complicates code.
