本文实例分析了java序列化与反序列化操作。分享给大家供大家参考，具体如下：
概述：
Java序列化是指把Java对象转换为字节序列的过程;而Java反序列化是指把字节序列恢复为Java对象的过程。
示例代码：
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
public class Test {
public static void main(String[] args) {
try {
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("D:/objectFile.obj"));
Customer customer = new Customer("中国人",23);
out.writeObject("你好!");
out.writeObject(new Date());
out.writeObject(customer);
out.writeInt(123);
List list = new ArrayList();
int i =0 ;
while(i<100) {
Customer customer2 = new Customer("中国人",i);
list.add(customer2);
i++;
}
HashMap hashMap = new HashMap();
hashMap.put("customer", list);
out.writeObject(hashMap);
out.close();
ObjectInputStream in = new ObjectInputStream(new FileInputStream("D:/objectFile.obj"));
System.out.println("obj1= " + (String) in.readObject());
System.out.println("obj2= " + (Date) in.readObject());
Customer obj3 = (Customer) in.readObject();
System.out.println("obj3= " + obj3);
int obj4 = in.readInt();
System.out.println("obj4= " + obj4);
Object obj5 = in.readObject();
System.out.println(obj5);
HashMap hash_map = (HashMap)obj5;
List l = (List) hash_map.get("customer");
System.out.println("size: " + l.size());
for(int ii=0; ii
