1.對象序列化,就是將Object轉換成byte序列,反之叫對象的反序列化。java
2.序列化流(ObjectOutputStream),writeObject 方法用於將對象寫入輸出流中;spa
反序列化流(ObjectInputStream),readObject 方法用於從輸入流中讀取對象。code
3.序列化接口(Serializeable)對象
對象必須實現序列化接口,才能進行序列化,不然會出現異常。這個接口沒有任何方法,只是一個標準。blog
package com.test.io; import java.io.FileInputStream; import java.io.FileOutputStream;import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public class ObjectSerialzeTest { /** * 對象的序列化 * @param file * @throws Exception */ public void ObjectOutput (String file) throws Exception { ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(file)); Student stu = new Student("002", "張四", 12); oos.writeObject(stu); oos.flush(); oos.close(); } /** * 對象的反序列化 * @param file * @throws Exception */ public void ObjectInput(String file) throws Exception { ObjectInputStream ois = new ObjectInputStream(new FileInputStream(file)); Student stu = (Student)ois.readObject(); System.out.println(stu.toString()); ois.close(); } public static void main(String[] args) throws Exception { String file = "F:\\javaio\\obj.dat"; ObjectSerialzeTest ost = new ObjectSerialzeTest(); ost.ObjectOutput(file); ost.ObjectInput(file); } }
