Or, if you don't really care about the value type, use Map<String, ?> as 
the parameter type.

public class MyComboBox {
    public MyComboBox(Map<String, ?> data) {...};
}

If you *do* care about the type, then make your ComboBox generic:

public class MyComboBox<V> {
    public MyComboBox(Map<String, V> data) {...};
}
