Е. F. All of the above. Which ones will be needed for file input/output? 2. Choose from below the instance field declarations associated with file processing. А. private String fileName; В. private double testScore; с. private PrintWriter outputFile; D. В only. Е. Both A and C. F. А, в, С. Enter a letter for the answer: 3. Code a createFile method that handles input/output exceptions through its header. public void createFile sert throws clause for handing an IO (input/output) exception. { System.out.printf("%nEnter the file name for test scores + " (WARNING: This will erase a pre-existing file!): ") ; fileName = input.nextLine (); //Complete creating outputFile a PrintWriter object for opening a file. }//END setFileName () : final void
