Examples of java.io.ObjectInputStream.readObject()

java.io.ObjectInputStream.readObject()
Read the next object from the receiver's underlying stream. @return the new object read. @throws IOException If an IO exception happened when reading the object @throws ClassNotFoundException If the class of one of the objects in the object graph could not be found @throws OptionalDataException If primitive data types were found instead of an object. @see ObjectOutputStream#writeObject(Object)
