Get size and name of selected file in JFileChooser?

Question

Good evening all, I was wondering what syntax I would use to get the size (mb) and the name of the selected file in my JFileChooser.

JFileChooser filedlg = new JFileChooser();
    filedlg.showOpenDialog(null);
    textField.setText(//File's name);
    textField_1.setText(//File's size);

What would I use to replace the comments? All help is appreciated.

   JFileChooser filedlg = new JFileChooser();
    filedlg.showOpenDialog(null);
    File selected = filedlg.getSelectedFile();
    textField.setText(selected.getName());
    textField_1.setText(selected.length());

    String fullName = selected.getAbsolutePath();

Also, the .length() gives size in bytes, so you will have to transform it to whatever you want after.

How do I get file path? Sorry, should have asked in original post ;) – tctawd May 10 '14 at 01:13
Edited my answer, check it again. – Jakkra May 10 '14 at 01:17
@TheCodingTraceur To get the absolute path of the file: `selected.getCanonicalPath()`. – AxiomaticNexus May 10 '14 at 01:17
absolutePath has always worked for me, but read more here about which to use: http://stackoverflow.com/questions/1099300/whats-the-difference-between-getpath-getabsolutepath-and-getcanonicalpath – Jakkra May 10 '14 at 01:19
Thanks both of you, I'll experiment with the 2 of them @YasmaniLlanes – tctawd May 10 '14 at 01:27
textField_1.setText(selected.length()); Does not work because .setText needs a string. – tctawd May 10 '14 at 01:34
