Examples of java.io.ObjectOutputStream

java.io.ObjectOutputStream
An ObjectOutputStream can be used to save Java objects into a stream where the objects can be loaded later with an ObjectInputStream. Primitive data (ints, bytes, chars, etc) can also be saved. @see ObjectInputStream @see ObjectOutput @see Serializable @see Externalizable
