The ``++readResolve()++`` method allows final tweaks to the state of an object during deserialization. Non-final classes which implement ``++readResolve()++``, should not set its visibility to ``++private++`` since it will then be unavailable to child classes.

== Noncompliant Code Example

----
public class Fruit implements Serializable { 
  private static final long serialVersionUID = 1;

  private Object readResolve() throws ObjectStreamException  // Noncompliant
  {...}

  //...
}

public class Raspberry extends Fruit implements Serializable {  // No access to parent's readResolve() method
  //...
}
----

== Compliant Solution

----
public class Fruit implements Serializable { 
  private static final long serialVersionUID = 1;

  protected Object readResolve() throws ObjectStreamException
  {...}

  //...
}

public class Raspberry extends Fruit implements Serializable {
  //...
}
