It treats each component in the container as a card. Only one card is visible at a time, and the container acts as a stack of cards. The first component added to a <code>CardLayout</code> object is the visible component when the container is first displayed. <p> The ordering of cards is determined by the container's own internal ordering of its component objects. <code>CardLayout</code> defines a set of methods that allow an application to flip through these cards sequentially, or to show a specified card. The <CODE>CardLayou#addLayoutComponent</CODE> method can be used to associate a string identifier with a given card for fast random access.<P><DL><DT><B>Since: </B><DD>JDK1.0</DD><DT><B>See Also:
