ReadObjectAndWriteObjectPrivate

Reports Serializable classes where the readObject or writeObject methods are not declared private. There is no reason these methods should ever have a higher visibility than private.

A quick-fix is suggested to make the corresponding method private.

Example:

public class Test implements Serializable {
    public void readObject(ObjectInputStream stream) {
      /* ... */
    }
  }

After the quick-fix is applied:

public class Test implements Serializable {
    private void readObject(ObjectInputStream stream) {
      /* ... */
    }
  }
