我的问题就是在发送频率和发送次数的文本框中输入数字 然后点击发送，然后将下拉框下面对应的txt文件发送之后的内容显示在页面上，发送的就是对应txt里面的内容，简单点说 发送10次点击发送然后页面上会将对应的txt文件内容复制10次到页面上显示出来

没有一个人会的吗

你的btn都没绑定点击事件吧

[Sunyiban]

developer.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent paramActionEvent) { int a = Integer.parseInt(fscsText.getText()); int b = Integer.parseInt(fxplText.getText()); try { String word = getFile("F:/test.txt"); for (int i = 0; i < a * b; i++) { text.append(word + "\n"); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); 加个能输出呀~
