Useful Java Code Snippets 7 - Animated GIF on JFrame

Let's start with writing the class that we are going to use as a panel in our JFrame.

gifAnimated.java;

/**
* Author : Berk Soysal
*/

package gifPlayer;

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.ImageIcon;
import javax.swing.JPanel;

public class gifAnimated extends JPanel{

  private static final long serialVersionUID = 1L; // to avoid the warning
  private final int width = 640;
  private final int height = 480;
 
  private Image gifFile;
 
  //Constructor
  public gifAnimated(){
  
    setFocusable(true);
    setPreferredSize(new Dimension(width, height));
    loadGif();
  }
 
 //Load the gif from the directory
  private void loadGif(){
  
   // file.gif is in the src folder
    ImageIcon intro = new ImageIcon(this.getClass().getResource("/file.gif"));
    gifFile = intro.getImage();
  }
 
  @Override
  public void paintComponent(Graphics g) {
    super.paintComponent(g);
  
    g.setColor(Color.BLACK); // set default color to black
    g.fillRect(0, 0, width, height);  // paint the background
    g.drawImage(gifFile, width/5, height/5, this);  //draw the animation to the panel
  
  }
}

After writing our gifAnimated class, now it's time to code our main class..
Main.java;
  

/**
* Author : Berk Soysal
*/

package gifPlayer;

import java.awt.EventQueue;
import javax.swing.JFrame;

public class Main extends JFrame {

  private static final long serialVersionUID = -4562593047521834395L; // to avoid the warning


  public Main() {

    add(new gifAnimated());

    setResizable(false);
    pack();

    setTitle("Title of the JFRAME");
    setLocationRelativeTo(null);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }


  public static void main(String[] args) {

    EventQueue.invokeLater(new Runnable() {
     @Override
     public void run() {           

      JFrame myframe= new Main();

      myframe.setVisible(true);                
     }
   });
 }
}
