04-17.eri-test 如何在Java中序列化和反序列化ArrayList

默认情况下，ArrayList可序列化。 这意味着您无需显式实现Serializable接口即可序列化ArrayList。 在本教程中，我们将学习如何序列化和反序列化ArrayList。

ArrayList的序列化：

ArrayList arrayList = new ArrayList<>(
Arrays.asList（“ A”，“ B”，“ C”，“ D”，“ E”）））;
尝试{
FileOutputStream fileOutputStream =新的FileOutputStream（“ data”）;
ObjectOutputStream objectOutputStream
=新的ObjectOutputStream（fileOutputStream）;

objectOutputStream.writeObject（arrayList）;

   objectOutputStream.close（）;
   fileOutputStream.close（）;

} catch（IOException e）{
e.printStackTrace（）;
}

ArrayList的反序列化：

尝试{
FileInputStream fileInputStream =新的FileInputStream（“ data”）;
ObjectInputStream objectInputStream
=新的ObjectInputStream（fileInputStream）;

   ArrayList<String> arrayList 
            = (ArrayList<String>) objectInputStream.readObject();
   System.out.println(arrayList);

   fileInputStream.close();
   objectInputStream.close();

} catch（IOException | ClassNotFoundException e）{
e.printStackTrace（）;
}
