下面是我的代码，要在点击按钮在文本中显示按钮名称
public class text
{
private JFrame frame;
private JTextField textField;
private JButton button;
public void go()
{
frame = new JFrame();
textField = new JTextField();
button = new JButton("button");
frame.add(textField, BorderLayout.NORTH);
frame.add(button, BorderLayout.CENTER);
button.addActionListener(new ButtonListener());
frame.pack();
frame.setVisible(true);
}
public void setText(String str){
textField.setText(str);
}
public static void main(String[] args)
{
text t = new text();
t.go();
}
}
class ButtonListener implements ActionListener{
@Override
public void actionPerformed(ActionEvent e)
{
text t = new text();
t.setText(e.getActionCommand());
}
}
