如何在Java中的Jcombobox中使用浮点枚举

Question

I have an enum class that uses floats for its values eg

public enum Size {

    SMALL(10.50f),MEDIUM(12.35f),LARGE(15.90f);

    private float value;

    Size(float value){ 
        this.value = value;
    }
    public float getValue(){
        return this.value;
    }
}

I want to use this enum to 'generate' the list that will be used for a Jcombobox where the user will select one of the sizes.

ddSize.setModel((Size.values()));

I'm trying to use the code above, however I get the following error:

error: incompatible types: Size[] cannot be converted to ComboBoxModel<String>
        ddSize.setModel((Size.values()));

I need a way for me to be able to use the float enums without getting this error, if possible.

Answer 1

setModel took a ComboBoxModel<E> , so you can use DefaultComboBoxModel to fill the JComboBox like so :

ddSize.setModel(new DefaultComboBoxModel(Size.values()));

---

to make sure it works :

IntStream.range(0, ddSize.getItemCount())
        .forEach(index -> System.out.println(ddSize.getItemAt(index)));

Outputs

SMALL
MEDIUM
LARGE
