Let us first set a JButton:
JButton btn = new JButton("DemoButton");
Now, attach action listener:
btn.addActionListener(new ClickListener());
If you have an ActionListener attached to your button it'll fire when you call the method doClick():
btn.doClick();
The following is an example to call JButton doClick() method to simulate a click action:
Example
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JOptionPane;
public class SwingDemo {
public static void main(final String args[]) {
JButton btn = new JButton("DemoButton");
btn.addActionListener(new ClickListener());
JOptionPane.showMessageDialog(null, btn);
btn.doClick();
}
}
class ClickListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
System.out.println("Clicked!");
}
}
Output
On clicking “DemoButton” above, the following is the output visible:
