This method is used to write and save data in Java. I am not quite sure what is going on here. Could someone please comment this code so I can get a better understanding? if(input == 'S') { try { FileOutputStream f0; file = new FileOutputStream("savedGame"); ObjectOutputStream oOStrm = new ObjectOutputStream(file); oOStrm.writeObject(this); oOStrm.close(); System.out.println("Game saved"); } catch (IOException e) { e.printStackTrace(); System.out.println("Save unsuccessful"); } } return; }
