I was wondering how to get java to save a text file named hello.txt
to the desktop without writing
"C:\\Users\\Austin\\Desktop"
Any help would be great. so like:
FileWriter fileWriter = new FileWriter(fileName.getText(), true);
..and the fileName.getText()
is just going to be the 'hello'.
UPDATE: i think that i would be able to use the jfilechooser, so would this work?
JFileChooser chooser = new JFileChooser();
chooser.setVisible(true);
would that work? and if so, how would i get it to save the file using the selection in there? im a noob.... :(
import java.io.File;
class FindDesktopOnWindows {
public static void main(String[] args) throws Exception {
if (System.getProperty("os.name").toLowerCase().indexOf("win")<0) {
System.err.println("Sorry, Windows only!");
System.exit(1);
}
File desktopDir = new File(System.getProperty("user.home"), "Desktop");
System.out.println(desktopDir.getPath() + " " + desktopDir.exists());
java.awt.Desktop.getDesktop().open(desktopDir);
}
}
I forgot different Locales. Very fragile code (even for code that starts out OS specific). See my comment below re. OS X/ JFileChooser
.
..how the
(System.getProperty("user.home"), "Desktop")
works..
Oracle helpfully provides docs for this kind of thing.
See System.getProperty(String)
& new File(String,String)
.
I'll cede to an expert (or a user) on this, but I don't think OS X supports any application icons or document icons directly on the ..start screen, default look, whatever.. Probably better to offer the end user a JFileChooser
pointing to user.home
and ask them to save the document to the desktop (or wherever they feel like).
这会指向桌面目录:
javax.swing.filechooser.FileSystemView.getFileSystemView().getHomeDirectory()
User.home工作,但只是硬编码目录应该没问题。
