通过 java GUI 写入文本文件

Question

我创建了一个 Java GUI，可用作包含 6 个问题的调查问卷。对于六个问题中的每一个问题，我有 4 个选择，i、ii、iii、iv 供用户选择，然后在文本框中键入四个选项之一，然后单击“输入”按钮进入下一个问题。回答完所有六个问题后，它将跳转到完成页面。

我想将每个问题的输入值（在文本框中）写入文本文件。因此，在单击“输入按钮”回答所有六个问题后，我可以在文本文件中看到类似“i ii iii i ii iii”的内容。

有办法做到吗？

这是我的代码：

当然，类似的东西

OutputStream out = new FileOutputStream("/path/to/your/file");
out.write(answer.getBytes());
out.close();
