You choose a file but don't create it write anything to it. The file will not be created until you actually create it or write something to it, for example with

FileWriter writer = new FileWriter(fileToSave);
writer.write("Hello!");
writer.close();

First, get the file you want to save as a File. Then, write it to a new directory using BufferedWriter to a new directory.

final JFileChooser fc = new JFileChooser();
int returnVal = fc.showSaveDialog(aComponent); //parent component to JFileChooser
if (returnVal == JFileChooser.APPROVE_OPTION) { //OK button pressed by user
        File file = fc.getSelectedFile(); //get File selected by user
        o = new BufferedWriter(new FileWriter(file)); //use its name
        //write things here
        o.flush();
        o.close();
}

Look at How to save file using JFileChooser in Java? and How to save a txt file using JFileChooser?
