java:序列化Serializable 接口
public class SerializePerson implements Serializable { private String name;
private int age; public SerializePerson(String name, int age)
{ this.name = name;
this.age = age;
} @Override
public String toString() {
return "姓名:" + name + ", 年龄:" + age;
} }
一,单对象序列化
public static void main(String[] args) throws Exception, Exception {
// TODO 自动生成的方法存根 if( args[0].equals("set") )
{ setPseron(); }else if( args[0].equals("get") )
{
getPseron();
}else{
System.out.println("抱歉,你什么都没有输入");
}
System.out.println(args[0]); } public static void setPseron() throws Exception, IOException
{ File file = new File("F:"+File.separator+"work"+File.separator+"work"+File.separator+"a.txt");
ObjectOutputStream oobs = null;
oobs = new ObjectOutputStream( new FileOutputStream(file) );
oobs.writeObject(new SerializePerson("张三",22));
oobs.close(); } public static void getPseron() throws Exception, IOException
{
File file = new File("F:"+File.separator+"work"+File.separator+"work"+File.separator+"a.txt");
ObjectInputStream oips = null;
oips = new ObjectInputStream( new FileInputStream(file) );
Object obj = oips.readObject();
SerializePerson per = (SerializePerson) obj;
System.out.println(per); }
二。多对象,多数组序列化
public static void main(String[] args) throws Exception, Exception
{ if(args[0].equals("set"))
{ setPerson();
}else if(args[0].equals("get"))
{
Object obj = getPerson();
SerializePerson per[] = (SerializePerson[]) obj;
print(per); }else{
System.out.println("请输入一个操作");
} } public static void setPerson() throws Exception, IOException
{
File file = new File("F:"+File.separator+"work"+File.separator+"work"+File.separator+"person.per");
ObjectOutputStream oopt = new ObjectOutputStream( new FileOutputStream(file) ); SerializePerson per[] = {new SerializePerson("张三",22), new SerializePerson("李四",44), new SerializePerson("王五",33)};
oopt.writeObject(per);
oopt.close();
} public static Object getPerson() throws Exception, IOException
{
File file = new File("F:"+File.separator+"work"+File.separator+"work"+File.separator+"person.per");
ObjectInputStream lis = null;
lis = new ObjectInputStream( new FileInputStream(file) );
Object obj = null;
obj = lis.readObject();
lis.close();
return obj; } public static void print(SerializePerson per[])
{
for(SerializePerson p: per)
{
System.out.println(p);
}
}
