Saving file with specified file extention
May 25th, 2010, 6:06am  
Hi,
i'm asking for help with saving files.
A have got a following code:

It saves file only if i set the *.xxx extention

Code:

FileDialog fd = new FileDialog(this.frame);
    fd.setMode(FileDialog.SAVE);
    fd.setLocation(50, 50);
    fd.show();
    String dir = fd.getDirectory();
    String file = fd.getFile();
    if( dir != null && file != null && file.indexOf(".xxx") != -1) {
	PrintWriter out;
	out = createWriter(dir+file);
	
	out.println("text");

	out.flush();
	out.close();
    }


I would like to run file dialog than chose a directory and enter only file name.
i want file dialog to save my file with presed extention 'xxx'.
How to specify file extention to be add to any saved files without writing it in after file name in filedialog ???????????

HELP

I don't understand your question. What is the problem of adding manually the file extension if it is not there?

BTW, don't do file.indexOf(".xxx") != -1, you rather want: file.endsWith(".xxx")

So, it should be something like:
Code:
String dir = fd.getDirectory();
String file = fd.getFile();
if (dir != null && file != null) {
  String path = dir + file;
  if (!file.toLowerCase().endsWith(".xxx")) {
    path += ".xxx";
  }
  PrintWriter out;
  out = createWriter(path);
	
  out.println("text");

  out.close(); // Close does the flush, actually
}
