How to implement flows here??

Question

Java

i have a myPanel class that is inherited from the JPANEL class and a myFrame class that is inherited from the JFRAME class.
I need to make sure that there is a myPanel class in the stream. I would only add objects of the myPanel class in the myFrame class through the stream.
As a result of the work, the photo should move, the more the better. Here is my code:

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JPanel;
import javax.swing.Timer;

import javax.swing.JFrame;
public class Main  {

  public static void main(String[] args) {
    int width = 400;
    int height  = 400;
    
    MyFrame frame = new MyFrame(width, height);
    

  }


}
public class MyFrame extends JFrame  {
  
  Dimension dimension = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
  
  public MyFrame(int width,int height){
    
    
    int x = dimension.width/2-(width/2);
    int y = dimension.width/2-(height/2);
    setBounds(x, y, width, height);
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    
    MyPanel panel = new MyPanel("src/1.png",50);
    add(panel);
    panel.setBounds(0, 0, width, height);
    
    MyPanel panel1 = new MyPanel("src/2.png",50);
    add(panel1);
    panel1.setBounds(0, 150, width, height);
    

    MyPanel panel2 = new MyPanel("src/3.png",50);
    add(panel2);
    panel2.setBounds(0, 200, width, height);
  }


}
public class MyPanel extends JPanel {

  Image img = null;
  
  int a = 0;
  int b = 400;

  int x = a +(int)(Math.random()*b);
  int y = a +(int)(Math.random()*b);
  public MyPanel(String imageName,int t) {
    try {
      img = ImageIO.read((new File(imageName)));
    } catch (IOException e) {
    }

    Timer time = new Timer(t, new ActionListener() {

      @Override
      public void actionPerformed(ActionEvent e) {
        repaint();

      }
    });
    time.start();

  }

  public void paintComponent(Graphics graphics) {

    graphics.drawImage(img, x, y, null);

    x++;
    
  if(x>400) {
    
    x=0;
  }
    

  }


}

Answer 1

You can make mypanel implements runnable and write the run() method there, in which to move the panel along the frame.
