I am not sure if enums in java store functions.

[subhajit20]

Yes it does, because I have created one java program where I declared a enum and inside it defined the toString function and it worked totally final without any issue

[sanketshevkar]

Okay, thanks for clarification. I'm not much proficient in Java. @mttrbrts can you please review this?

Here is a sample code snippet

public class Main{
    public enum State {
        MA,
        NY,
        CO,
    
        // Override the toString() method for the entire enum type
        @Override
        public String toString() {
            return name();
        }
    }
    public static void main(String[] args) {
        // Using the enum constants
        State state1 = State.MA;
        State state2 = State.NY;
        String ma = state1.toString();  // This will call the overridden toString() method
        
        // Printing the enum constants
        System.out.println("State 1: " + ma);
    }
}

Hey @sanketshevkar Have one question, How can I pass extra parameters like parameters.filewriter as show in the code.. I mean to say can we pass other parameter like this parameters.x ?

concerto-codegen/lib/codegen/fromcto/java/javavisitor.js

Lines 142 to 146 in 7c14d70

	parameters.fileWriter.writeLine(0, 'public enum ' + enumDeclaration.getName() + ' {' );
	enumDeclaration.getOwnProperties().forEach((property) => {
	property.accept(this, parameters);
	});

yes, you can. it is an options object on the visitor. (answered by @dselman on the Tech WG call)

Okay ... I am assuming is that something like this parameters.options
