java:谁有文件"打开"和"保存"对话框部分的原码啊,就便是功能不全也可以啊

直接用类FileDialog不就得了

public class Dakai{
public static void main(String ar[])
{ JFileChooser file = new JFileChooser();
file.showOpenDialog(null);
File fl = file.getSelectedFile();
char b[] = new char[ (int) fl.length()];
try{
FileReader fileinput = new FileReader(fl);
fileinput.read(b);
fileinput.close();
file.showSaveDialog(null);
File fout = file.getSelectedFile();
FileWriter fileout = new FileWriter(fout);
fileout.write(b);
fileout.close();
}catch(IOException e){

}
}
}
