[英]How can I save multiple files at the same time in Jfilechooser from JList?
[英]How can I set the save path for new files in JFileChooser?
我有一個使用JFileChooser的對話框。 當我通過FileOutputStream
保存文件時,我想將其另存為用戶想要的路徑中的file.txt
。 但是它總是保存在c:/user/Document
。
這是代碼:
DownLoadDialog downloadDialog = new DownLoadDialog();
int result = downloadDialog.showSaveDialog(queryPanel);
if (result == downloadDialog.APPROVE_OPTION) {
File file = downloadDialog.getSelectedFile();
//String parth =file.getPath();
//System.out.println(parth);
//if(file.exists()) {
//int response = JOptionPane.showConfirmDialog (null,
// "Overwrite existing file?","Confirm Overwrite",
// JOptionPane.OK_CANCEL_OPTION,JOptionPane.QUESTION_MESSAGE);
//if(response == JOptionPane.OK_OPTION) {}
//} else {
if (resultGoogleSearch > 0) {
{
String parth = new File(downloadDialog.getSelectedFile().
getAbsolutePath().concat(".txt")).toString();
System.out.println(parth);
for (int i = 0; i < resultGoogleSearch; i++) {
String[] temp = googleSearchResult.get(i).split("<br>");
//String resultURL = temp[0];
//File dir = downloadDialog.getCurrentDirectory();
try {
FileOutputStream googleReuslt = new FileOutputStream(
downloadDialog.getSelectedFile().getAbsolutePath()
+ ".txt");
OutputStreamWriter writer = new
OutputStreamWriter(googleReuslt);
BufferedWriter buffer = new BufferedWriter(writer);
writer.write(temp[0]);
writer.close();
buffer.close();
} catch (FileNotFoundException fEx) {
} catch (IOException ioEx) {
}
}
}
JOptionPane.showMessageDialog(IDRSApplication.idrsJFrame,
IDRSResourceBundle.res.getString("successful"));
}
問題在這里:為什么我不能設置新文件的路徑?
FileOutputStream googleReuslt = new FileOutputStream(
downloadDialog.getSelectedFile().getAbsolutePath() + ".txt");
OutputStreamWriter writer = new OutputStreamWriter(googleReuslt);
BufferedWriter buffer = new BufferedWriter(writer);
writer.write(temp[0]);
writer.close();
buffer.close();
您提供的代碼可以按預期工作。 (至少在Linux下)。
我建議您進行SSCCE並更新您的問題。
