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) {...};
}
