Thread: what is "SUCCESS" in method

Hi guys!
I have some classes that i have to write javadocs to. So, there are some methods that return success, like:

public string do smth(){
 
if () {return SUCCESS;}
else {return (something else, in this case some INPUT);}
 
}

What is this SUCCESS and INPUT? They are not variables, for no such variables were initialized. Is success something similar to true? By the method type it should be a string, but such string wasnt initialized, so im confused, please help.

Sorry if i posted this in some wrong place.

Judging from the naming convention I would say they are static final variables of type String (or null).

Yes, that was pseudo code. Problem is that i cant use the ctrl+hover mouse over methods or fields, because i am viewing the project via separete .java files. I guess SUCCESS and INPUT really are some final Strings declared in some of the inherited classes, like Cornix suggested.

Yes, that is what i meant. There was some irrelevant code , and then the return SUCCESS;

Now i am certain that SUCCESS is a string, because in some String.format it was adressed as '%s'

HI! May I ask if your class is EXTENDING THE ACTION Interface? If so, SUCCESS, INPUT, etc. are CONSTANT values which represents a corresponding string value. I'm using this when doing a Struts2 project.
