Just make the class implement the interface Serializable:

Note that the interface doesn't have any methods, so you don't need to implement any methods.

Note: If you cannot modify the class, then it's not going to be possible. You can't make any object serializable.

More a beginner's question.

In theory it is easy; you just add "implements Serializable" after the class name. Serializable is a tagging interface (also called a marker interface) which has no methods.

In practice you need to ensure that all its fields are instances of Serializable classes too.
 
It is sorta covered in the JavaRanch Style Guide.
