將編碼過濾器添加到Java中的JFileChooser

Question

如何將編碼選項「UTF-8」添加到我的JFileChooser保存對話框中。

JFileChooser fileChooser = new JFileChooser(); 
    FileNameExtensionFilter filter1 = new FileNameExtensionFilter("TEXT", ".txt"); 

     fileChooser.setFileFilter(filter1); 
     fileChooser.setDialogTitle("Specify a file to save"); 
       int returnVal = fileChooser.showSaveDialog(null); 
       if (returnVal == JFileChooser.APPROVE_OPTION) 
       { 

        File file = fileChooser.getSelectedFile(); 
       //do something 
       }

使用標準Java：

String aString = "Test\nWithNewline"; 
try { 
    Writer out = new BufferedWriter(new OutputStreamWriter(
         new FileOutputStream("outfilename"), "UTF-8")); 
    out.write(aString); 
    out.close(); 
} catch (IOException e1) { 
    e1.printStackTrace(); 
} 

使用Apache Commons：中

File f = new File("outfilename"); 
FileUtils.writeStringToFile(f, aString, "UTF-8");
