Can I avoid a FileNotFoundException when i run program on 1st time?

Question

I did a google on theis exception and didnt find the help i need. I just want an example of avoiding this exception on a 1st run of program that has had no data saved or entered. Is there a method to see if the file exists?

Answer 1

What package i need to import? I have already imported the java.io wildcard package and the compiler cant find the exists() ? FileInputStream fis = new FileInputStream("PhoneBook.dat");
               if(fis.exists()){
                    ObjectInputStream os = new ObjectInputStream(fis);
                    phoneListRestore = (ArrayList<ContactDetails>)os.readObject();
                    os.close();
          }
