CardLayout in Java Example

The java.awt.CardLayout layout manager is significantly different from the other layout managers. Unlike other layout managers, that display all the components within the container at once, a CardLayout layout manager displays only one component at a time (The component could be a component or another container).

Each component in a container with this layout fills the entire container. The name cardlayout evolves from a stack of cards where one card is piled upon another and only one of them is shown. In this layout, the first component that you add to the container will be at the top of stack and therefore visible and the last one will be at the bottom.

Java.awt.CardLayout the class selected the following constructors and methods: 

import java.awt.*;   
 import java.awt.event.*; 
 class CardLayoutExample extends Frame implements ActionListener 
 { 
      CardLayout card = new CardLayout(20,20); 
      CardLayoutExample() 
      { 
          setLayout(card); 
          Button Btnfirst = new Button("first "); 
          Button BtnSecond = new Button ("Second"); 
          Button BtnThird = new Button("Third"); 
          add(Btnfirst,"Card1"); 
          add(BtnSecond,"Card2"); 
          add(BtnThird,"Card3"); 
          Btnfirst.addActionListener(this); 
          BtnSecond.addActionListener (this); 
          BtnThird.addActionListener(this); 
      } 
      public void actionPerformed(ActionEvent e) 
      { 
        card.next(this); 
      } 
 } 
    class CardLayoutJavaExample 
    { 
         public static void main(String args[]) 
        { 
             CardLayoutExample frame = new CardLayoutExample(); 
             frame.setTitle("CardLayout in Java Example"); 
             frame.setSize(220,150); 
             frame.setResizable(false); 
             frame.setVisible(true); 
        } 
    }
