[英]saving file using JFileChooser at any location
你好,我正在嘗試將文件保存在Jfilechooser指定的位置,現在的情況是,當用戶單擊“保存”時,將在項目方向上以名稱標題創建文件,但是我需要給用戶選擇保存文件的位置,並且使用JFileChooser選擇他喜歡的名稱
if(buttonPressed.equals(save)){
File myFile = new File("title");
final JFileChooser fc = new JFileChooser();
int returnVal = fc.showSaveDialog(null);
fc.setSelectedFile(myFile);
if (returnVal == JFileChooser.APPROVE_OPTION) {
try (PrintWriter writer = new PrintWriter(myFile)) {
for (int i =0 ; i< cModel.getRowCount(); i++)
{
sData.add(cModel.getValueAt(i, 1).toString());
eData.add(cModel.getValueAt(i, 2).toString());
tData.add(cModel.getValueAt(i, 3).toString());
writer.println(i+1 + "\n");
writer.println(sData.get(i)+" --> " + eData.get(i));
writer.println(tData.get(i));
writer.println("\n");
}
}catch(FileNotFoundException ioEx){
}
}
}
嘗試
JFrame choose = new JFrame();
choose.setTitle("Save To ...");
final JFileChooser fc = new JFileChooser();
int returnVal = fc.showSaveDialog(choose);
