Question

  }
}
);

Answer 1

楼上,12个Jbutton,我如何才能获得他的操作权呢,我没有定义过button1

Answer 2

void jButton1_actionPerformed(ActionEvent e) {
jButton1.setText("aaaaaaaaaaaaaa");  }你说得是这个吗？

Answer 3

private JButton jButton1 = new JButton();
jButton1.addActionListener(new java.awt.event.ActionListener() {
      public void actionPerformed(ActionEvent e) {
        jButton1_actionPerformed(e);
      }
void jButton1_actionPerformed(ActionEvent e) {
jButton1.setText("aaaaaaaaaaaaaa");
  }
这样就可以了吧！！
