Adding items to a JComboBox

I use a combo box on panel and as I know we can add items with the text only

comboBox.addItem('item text');

But some times I need to use some value of the item and item text like in html select:

<select><option value="item_value">Item Text</option></select>

Is there any way to set both value and title in combo box item?

For now I use a hash to solve this issue.


Wrap the values in a class and override the toString() method.

class ComboItem
    private String key;
    private String value;

    public ComboItem(String key, String value)
        this.key = key;
        this.value = value;

    public String toString()
        return key;

    public String getKey()
        return key;

    public String getValue()
        return value;

Add the ComboItem to your comboBox.

comboBox.addItem(new ComboItem("Visible String 1", "Value 1"));
comboBox.addItem(new ComboItem("Visible String 2", "Value 2"));
comboBox.addItem(new ComboItem("Visible String 3", "Value 3"));

Whenever you get the selected item.

Object item = comboBox.getSelectedItem();
String value = ((ComboItem)item).getValue();
