Four sets of reading and writing programs

First set: Byte stream read Write scheme

FileInputStream: Byte stream read text file

FileOutputStream: Byte stream write to hard disk

Second set: Character Stream read Write scheme

FileReader: Character Stream reads text

FileWriter: Character Stream writes text

BufferedReader: Custom cache size, read text 8,192 Char

BufferedWriter: Writing text

Generally used in combination with FileReader and filewriter

Fourth set: can read binary (img image, etc.)

DataInputStream: Loading the local img into memory

DataOutputStream:: Writes the In-memory binary data to a file on the hard disk.

Serialization and deserialization:

//Serialization of List<dog> list=New arraylist<dog>(); List.add (New Dog ("Peas",15)); List.add (New Dog ("Peas 2",15)); F ObjectOutputStream oos=NewObjectOutputStream (FOS); Oos.writeobject (list); Fos.close (); Oos.close (); System.Out.println ("Serialization succeeds!"); Deserialization fileinputstream fis=new FileInputStream ( "save.bin "); ObjectInputStream ois=new ObjectInputStream (FIS); List<dog> list= (List<dog>for (Dog dog:list) {system..println (Dog.getname ());} Note: 0102public String msg
