How to convert enum value to int?

Question

I have a function which return a type int. However, I only have a value of the TAX enumeration.

How can I cast the TAX enumeration value to an int?

public enum TAX {
    NOTAX(0),SALESTAX(10),IMPORTEDTAX(5);

    private int value;
    private TAX(int value){
        this.value = value;
    }
}

TAX var = TAX.NOTAX; // This value will differ

public int getTaxValue()
{
  // what do do here?
  // return (int)var;
}

Sometime some C# approach makes the life easier in Java world..:

class XLINK {
static final short PAYLOAD = 102, ACK = 103, PAYLOAD_AND_ACK = 104;
}
//Now is trivial to use it like a C# enum:
int rcv = XLINK.ACK;
