# ContainerAdapter

## Name

ContainerAdapter

##

## Description

The `ContainerAdapter` class implements the methods of `ContainerListener` with empty functions. It may be easier for you to extend `ContainerAdapter`, overriding only those methods you are interested in, than to implement `ContainerListener` and provide the empty functions yourself.

       extends java.lang.Object
       implements java.awt.event.ContainerListener {

      public void componentRemoved (ContainerEvent e);
    }
