Java 对象序列化和反序化例子

public static void writeObject(Object o){

File file = new File("d:","user.tmp");
if(file.exists()){
file.delete();
}
FileOutputStream fos;
try {
fos = new FileOutputStream(file);

// ObjectOutputStream是核心类

ObjectOutputStream oos = new ObjectOutputStream(fos);

oos.writeObject(o);

oos.close();

fos.close();
} catch (Exception e) {

e.printStackTrace();

}finally{
System.out.println("TestSerializable write success!");
}

}
