 import java.io.*; class TransientVariables implements Serializable { int num1 = 20; transient int num2 = 30; public static void main(String[] args) throws Exception { TransientVariables t = new TransientVariables(); FileOutputStream fo = new FileOutputStream("input.txt"); ObjectOutputStream oo = new ObjectOutputStream(fo); oo.writeObject(t); FileInputStream fi = new FileInputStream("input.txt"); ObjectInputStream oi = new ObjectInputStream(fi); TransientVariables t1 = (TransientVariables) oi.readObject(); System.out.println("num1: " + t1.num1); System.out.println("num2: " + t1.num2); } } 

num1: 20 num2: 30

num1: 0 num2: 30

num1: 20 num2: 0

num1: 0 num2: 0
