You must implement this interface to serialize the objects of this class and serialize the class into a byte stream. Serializable is a marked interface, so there is no need to override the method. For example.

This is all the input and output after serializing the objects of class T.

Import java.io. *;

Public class TestObjectIO {

Public static void main(String args[]) throws an exception {

T T = new T()；

t . k = 8；

file output stream fos = new file output stream(" d:/share/Java/io/testobjectio . dat ")；

object output stream OOS = new object output stream(fos)；

OOS . writeobject(t)；

OOS . flush()；

OOS . close()；

file inputstream fis = new file inputstream(" d:/share/Java/io/testobjectio . dat ")；

ObjectInputStream ois = new ObjectInputStream (FIS);

T tReaded =(T)ois . read object()；

system . out . println(treaded . I+" "+treaded . j+" "+treaded . d+" "+treaded . k)；

}

}
