DeserializeFile2Object.java

 

package com.zuidaima.util;

import java.io.FileInputStream;
import java.io.ObjectInputStream;

/**

public class DeserializeFile2Object {

    public static void main(String[] args) {
        Address address = deserialzeAddress();
        System.out.println(address);
    }

    public static Address deserialzeAddress() {

        Address address;

        try {

            FileInputStream fin = new FileInputStream("c:/address.ser");
            ObjectInputStream ois = new ObjectInputStream(fin);
            address = (Address) ois.readObject();
            ois.close();

            return address;

        } catch (Exception ex) {
            ex.printStackTrace();
