Usage

From source file:MainClass.java

public static void main(String[] a) throws Exception {

    List list = Arrays.asList(new String[] { "A", "B", "C", "D" });
    FileOutputStream fos = new FileOutputStream("list.ser");
    ObjectOutputStream oos = new ObjectOutputStream(fos);
    oos.writeObject(list);//  ww w .jav a2  s  .c om
    oos.close();

    FileInputStream fis = new FileInputStream("list.ser");
    ObjectInputStream ois = new ObjectInputStream(fis);
    List anotherList = (List) ois.readObject();
    ois.close();

    System.out.println(anotherList);
}

From source file:Main.java
