title: Clear selected file form JFileChooser
body: <p>I want to unselect the file from <code>JFileChooser</code>, when i click some button. 
  For example, if i click "Reset" button, the selected file from <code>JFileChooser</code> will be unselect. </p>
  
  <p>Here's the code of my <code>JFileChooser</code>:</p>
  
  <pre><code> public void fileChoose(){
      JFileChooser chooser = new JFileChooser();
      chooser.showOpenDialog(null);
      chooser.setCurrentDirectory(new File(System.getProperty("user","home")));
      FileNameExtensionFilter filter = new FileNameExtensionFilter("jpg", "png");
      File file = chooser.getSelectedFile();
      String path = file.getAbsolutePath();
  </code></pre>
  
  <p>And here the Reset button code :</p>
  
  <pre><code>private void clearAllField(){
      nik_input.setText("");
      name_input.setText("");
      born_input.setText("");
      birth_date_input.setDate(null);
      gender_input.setSelectedIndex(0);
      address_input.setText("");
      job_input.setText("");
  </code></pre>
  
  <p>Thanks.</p>
