Java IO——DataOutputStream & DataInputStream

String file="H:\\Lhc\\diary.txt";DataOutputStream dos=new DataOutputStream(new FileOutputStream(file));dos.writeInt(10);dos.writeInt(-10);dos.writeLong(10l);dos.writeDouble(10.3);dos.writeUTF("水田"); //utf-8写出dos.writeChars("水田奈落");//采用utf-16be编码写出dos.close();IOUtil.printHex(file);

String file="H:\\Lhc\\diary.txt";IOUtil.printHex(file);DataInputStream dis=new DataInputStream(new FileInputStream(file));int i=dis.readInt();System.out.println(i);
