How to convert enum value to int?

Tags: ,



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;
}

Answer

You’d need to make the enum expose value somehow, e.g.

public enum Tax {
    NONE(0), SALES(10), IMPORT(5);

    private final int value;
    private Tax(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }
}

...

public int getTaxValue() {
    Tax tax = Tax.NONE; // Or whatever
    return tax.getValue();
}

(I’ve changed the names to be a bit more conventional and readable, btw.)

This is assuming you want the value assigned in the constructor. If that’s not what you want, you’ll need to give us more information.
