 Main mm=new Main();
mm.setVisible(true);

step6.

import java.io.File;
import javax.imageio.ImageIO;
import javax.swing.JButton;

 create a public function to Capture Component for capture image. look like this
//this is capture component method now you use it
     public void captureComponent(Component component) {
Rectangle rect = component.getBounds();
JFrame editorFrame = new JFrame("captureComponent and save image");
              
try {
                      BufferedImage image = null;
                      
String format = "png";
String fileName = component.getName() + "." + format;
BufferedImage captureImage = 
new BufferedImage(rect.width, rect.height, 
BufferedImage.TYPE_INT_ARGB);
component.paint(captureImage.getGraphics());

ImageIO.write(captureImage, format, new File(fileName));
//save picture method
System.out.printf("The screenshot of %s was saved!", component.getName());

        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
this.setVisible(true);



this.validate();
                }
                catch(IOException ex) { }
   
    }

Step 9

 open Main.java file in design form and dbl click and do code this
captureComponent(this);
