         ObjectOutputStream oos = new ObjectOutputStream(fos);
         oos.writeObject(customer);
         oos.flush();
         oos.close();

         // Deserialization
         FileInputStream fis = new FileInputStream("customer.ser");
         ObjectInputStream ois = new ObjectInputStream(fis);
         Customer decustomer = (Customer) ois.readObject();
         ois.close();
         System.out.println("Customer after serialization: " + decustomer);
      } catch (IOException | ClassNotFoundException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
   }

}

class Customer implements Serializable {
   /**
   *
   */
   private static final long serialVersionUID = -1943599317632365868L;
   private String name;
   private String address;

   public Customer(String name, String address) {
      super();
      this.name = name;
      this.address = address;
   }

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }

   public String getAddress() {
      return address;
   }

   public void setAddress(String address) {
      this.address = address;
   }

   @Override
   public String toString() {
      return "Customer [name=" + name + ", address=" + address + "]";
   }

}

Output

Customer after serialization: Customer [name=Vinod, address=Bangalore]
