Answer 1

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class A extends JFrame implements MouseListener {
private JButton btn = new JButton("右键点我");

public A() {
this.setTitle("test");
this.setSize(300, 200);

this.add(btn);
btn.addMouseListener(this);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
}

public void actionPerformed(ActionEvent e) {
}

public static void main(String[] args) {
new A();
}

public void mouseClicked(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON3) {//右键点击
btn.setText("H");
}
}

public void mouseEntered(MouseEvent e) {
}

public void mouseExited(MouseEvent e) {
}

public void mousePressed(MouseEvent e) {
}

public void mouseReleased(MouseEvent e) {
}

}
