This class implements accessibility support for the JComboBox class. It provides an implementation of the Java Accessibility API appropriate to Combo Box user-interface elements.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

public int getAccessibleChildrenCount()
```
    Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.

    Returns:
    
    the number of accessible children in the object.
  - getAccessibleChild
```
public Accessible getAccessibleChild(int i)
```
    Returns the nth Accessible child of the object. The child at index zero represents the popup. If the combo box is editable, the child at index one represents the editor.
    
    Overrides:
    
    getAccessibleChild in class JComponent.AccessibleJComponent
    
    Parameters:
    
    i - zero-based index of child

```
public AccessibleStateSet getAccessibleStateSet()
