how to deserialize an object from a file that has multiple serialized objs?
In the below program i am serializing multiple objects into a single file & de-serializing all of them.
class ObjectOutputStreamAppendextends ObjectOutputStream
{
ObjectOutputStreamAppend(OutputStream os)throws IOException
{
super(os);
}
@Override
protectedvoid writeStreamHeader()throws IOException
{
reset();
}
publicstaticvoid main(String arg[])throws Exception
{
File f =new File("serial");
f.delete();
FileOutputStream fos =new FileOutputStream(f,true);
ObjectOutputStream oos =new ObjectOutputStream(fos);
oos.writeObject("hello");
oos.writeObject(new Integer(2));
oos.writeObject("world");
oos.writeObject(new Integer(3));
oos.flush();
oos.close();
FileInputStream fis =new FileInputStream(f);
ObjectInputStream ois =new ObjectInputStream(fis);
for (int i=0; i<4; i++)
System.out.println(ois.readObject());
}
}
Output is:
hello
2
world
3
The above program reads all the objects written into the file one by one.
Is there any way to read a particular object randomly? For eg. i want to read only the 3rd object (world)? Is it possible read a particular object?
Thank you.
