Return String from enum

Question

I want to use this enum structure in order to return string.

public enum Exchanges {

    PROCESSING("processing");

    private final String type;

    Exchanges(final String type) {
        this.type = type;
    }

    public String getType() {
        return type;
    }

    @Override
    public String toString() {
        return type;
    }
}

When I use Exchanges.PROCESSING I get error:

Syntax error, insert "VariableDeclarators" to complete 
 LocalVariableDeclaration

How I can fix this issue?

Exchanges e = Exchanges.PROCESSING should work fine. Please show your code. — assylias

Yes, but I want to use the code in case like this: channel.exchangeDeclare(Exchanges.PROCESSING, BuiltinExchangeType.TOPIC); — Peter Penzov

channel.exchangeDeclare(String exchange , BuiltinExchangeType obj)

should be

channel.exchangeDeclare(Exchanges exchange , BuiltinExchangeType obj)

or you should change the method call

channel.exchangeDeclare(Exchanges.PROCESSING, BuiltinExchangeType.TOPIC);

to

channel.exchangeDeclare(Exchanges.PROCESSING.getType(), BuiltinExchangeType.TOPIC);

Thanks but is there a way to call just Exchanges.PROCESSING without getType()

Well surely there is. And it returns you an object of type Exchanges. Which is not a String.

Then don't use an enum. Because that's not how an enum works.

Yes. As @Ben said, maybe you want to use constants, not enums.
