Serialization in java

[Nikhilesh Reddy Chaduvula]

public class Team implements Serializable {
Coach coach = new Coach();
Player[] players = new Player[5];
}
public class Coach implements Serializable {
}

public class Player {
}

Can anybody explain me why this is going to work. What I mean is Serializable is applicable here
but Serializable is not applicable here

public class Team implements Serializable {
Coach coach = new Coach();
}
public class Coach {
}

The reason I am assuming is that all the array of objects are initialized to null and hence serialization applies here.
and if we change the above program as

public class Team implements Serializable {
Coach coach = nul;
}
public class Coach {
}

It is serializable.I am having hard time in understanding these things.
I have followed this forum
http://javapapers.com/core-java/object-construction-in-serialization/

Can any one correct/rectify me if my understanding is wrong.

Hi Nikhilesh,

If you slightly modify your code it would confirm if you are right or wrong. Change the line

Player[] players = new Player[5];

To

Player[] players = {new Player()};

Also please remember Serialization is not a part of SCJP exam objectives anymore...
