How to use JFileChooser.showOpenDialog to open a specific file?

Question

Right now I am able to open a up any file that I want, however the default file that opens up is My Documents. How can I set the default path to a file that is saved in my java project?

Right now this is what I have:

              try{
                  int option = chooser.showOpenDialog(MyPanel.this);//Chooser is my JFileChooser
                    if(option == JFileChooser.APPROVE_OPTION) {
                       //do stuff
                    }
              }catch(Exception ex){}

What do I have to pass into showOptionDialog() to open a folder if it is located in my java project?

You can use like

JFileChooser chooser = new JFileChooser("desired_current_directory");

or

chooser.setCurrentDirectory(new File("desired_current_directory"));

If you want to open My Pics folder under your project directory use

JFileChooser chooser = new JFileChooser("./My Pics");

cool that works! thanks! Is there another way to read that file without giving the full path name? The reason why I ask this is because if I where to give this project to someone and have it run on their computer, the path for them would not be the same. How can I get it to read from a folder, lets say named "My Pics", if it is saved in my java project? – mr nooby noob Sep 22 '15 at 19:00

You can either add directory to the constructor of JFileChooser like this:

JFileChooser fileChooser = new JFileChooser("directory");

or you can set the current directory using setCurrentDirectory(File dir):

fileChooser.setCurrentDirectory(new File("directory"));

It is probably easier to just set it with the constructor, but if you need to change it after creating the JFileChooser, use setCurrentDirectory(File dir).

You can either add directory to the constructor of JFileChooser like this:

 JFileChooser fileChooser = new JFileChooser();
    fileChooser.setCurrentDirectory(new File("put here your directory"));
    int result = fileChooser.showOpenDialog(getParent());
    if (result == JFileChooser.APPROVE_OPTION) 
    {
        File selectedFile = fileChooser.getSelectedFile();
        jTextField.setText(selectedFile.getAbsolutePath());
    }
