Conveniently map between enum and int / String

Question

When working with variables/parameters that can only take a finite number of values, I try to always use Java\'s enum, as in

public enum BonusT         


        

Answer 1

org.apache.commons.lang.enums.ValuedEnum;

To save me writing loads of boilerplate code or duplicating code for each Enum, I used Apache Commons Lang's ValuedEnum instead.

Definition:

public class NRPEPacketType extends ValuedEnum {    
    public static final NRPEPacketType TYPE_QUERY = new NRPEPacketType( "TYPE_QUERY", 1);
    public static final NRPEPacketType TYPE_RESPONSE = new NRPEPacketType( "TYPE_RESPONSE", 2);

    protected NRPEPacketType(String name, int value) {
        super(name, value);
    }
}

Usage:

int -> ValuedEnum:

NRPEPacketType packetType = 
 (NRPEPacketType) EnumUtils.getEnum(NRPEPacketType.class, 1);
