Question

Java编写一个图形界面

要求是左边有默认的例如“IP地址”“端口”“访问网址”等文字类别说明，右边和这些文字同一行是输入框，由用户输入数据。
左边大概8行左右，最后留一行没有文字类别说明，而由用户自行输入类别文字。
最下面正中一个按钮“生成文件”，用户点了之后会在C盘根目录下生成info.dat的文件，文件内容就是“IP=****** (换行)PORT=******”这样的内容。
如果代码过长可以发到我邮箱 milan.thiago.silva.33@gmail.com
好了之后效果如下图。
我现在图形界面应该可以出来，但是不知道怎么写到文件里面去。是用PrintWrite out么？

Answer 1

我觉得还是我的好些。。。
