一：需要序列化的类  
实现Serializable接口

package testfile;
    
    import java.io.Serializable;
    
    public class Person implements Serializable{ 
        private String name;
        private int age;
    
        public Person(String name, int age) {
            super();
            this.name = name;
            this.age = age;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
        /** * @param args */
        public static void main(String[] args) {
            // TODO Auto-generated method stub
    
        }
    
    }

二：具体实现方法

package testfile;
    
    import java.io.BufferedReader;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.FileReader;
    import java.io.FileWriter;
    import java.io.FilenameFilter;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.ObjectInputStream;
    import java.io.ObjectOutputStream;
    import java.io.PrintStream;
    import java.io.PushbackReader;
    import java.io.RandomAccessFile;
    
    public class TestFile { 
    
        /** * @param args */
        public static void main(String[] args) throws IOException{
    
            try {
    
                Person person = new Person("kirito", 2000);
                ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(new File("F:/download/testzzl.txt")));
                oos.writeObject(person);
    
                ObjectInputStream ois = new ObjectInputStream(new FileInputStream(new File("F:/download/testzzl.txt")));
                Person p = (Person) ois.readObject();
                System.out.println(p.getAge() +":"+ p.getName());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ClassNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    
    
    }
