求一个简单的Java界面

本文转载自 zilch_09 查看原文 2009/05/21 10 java/ 界面/ 简单

大体代码：
public class TestOut {
public void TK3(String fileName,String outfileName) throws IOException {
BufferedReader reader = new BufferedReader(new FileReader(new File(
fileName)));//从界面获取的输入文件位置
BufferedWriter bw = new BufferedWriter(new FileWriter(outfileName)); //将缓冲对文件的输出,输出
try
{ ...
bw.write(XXXXX);//从inputfileName读取数据输出到outputfileName
bw.newLine();//写一行结束换行
continue;
}
} catch (Exception e) {
e.printStackTrace();
} finally {
bw.flush(); //刷新该流的缓冲
bw.close(); //关闭流，释放资源
reader.close(); //关闭流，释放资源
}
}
public static void main(String[] args) throws IOException {
需求：做一界面，点打开显示文本浏览框
然后获取输入文件地址->inputfileName
再选择保存文件地址->outputfileName
TestOut tm = new TestOut();
tm.TK3(inputfileName,outputfileName);
}
}
现在就只需要界面，比较简单
JAVA新手，自己也正在学，但时间比较紧张，希望会的兄弟顺手解决下，谢谢

发不了图片怎么
大体就这样的：
标题：XX

输入文件位置：【输入框】【浏览按钮】

输出文件位置：【输入框】【浏览按钮】

【确定】【退出】

#2

SWT? SWING, 还是awt的?

我做了一个，自己用txt文件和jpg进行了测试，可以用，请方家指正。
给楼主个建议，使用具有可是编程能力的IDE进行GUI制作，事半功倍（我这个是用NetBeans6.1做的）

其实这个东西问题还是很多的：
1、从程序设计的角度说，我把功能实现和界面做在了一起，这是不好的；
2、操作过程，尤其是功能实现以后没有任何提示，这很不符合人机交互友好的要求；
3、等等
请高手多多指点。

强烈建议楼主看看《Java核心编程》第一卷，网上应该也有下载的

谢谢了
正在慢慢学，刚会一点，呵呵
