//--> cannot find variable selectedFile. error
FileReader i= new FileReader(selectedFile);
File output = chooser.getSelectedFile();
FileWriter o = new FileWriter(output);
String out = selectedFile.getName(); //getname of file

try
---> cannot find symbol method new bufferedReader (java.ioFile)

(BufferedReader reader = File.newBufferedReader(selectedFile)){
String line = null;
while ((line = reader.readLine()) != null) {
System.out.println(line);
