Serialize -> DeSerializeのサンプル。

Serialize処理とSerialize対象のクラスHoge。

package sample;

 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.io.ObjectOutput;
 import java.io.ObjectOutputStream;
 import java.io.Serializable;
 import java.util.Arrays;
 import java.util.Date;
 import java.util.List;

 public class SerializeSample {
     public static void main(String[] args) throws IOException, ClassNotFoundException {
         FileOutputStream file = new FileOutputStream("C:\\hoge");
         ObjectOutput out = new ObjectOutputStream(file);
        
         Hoge hoge = new Hoge("hoge");
         Hoge fuga = new Hoge("fuga");
         List<Hoge> list =    Arrays.asList(hoge, fuga);

         out.writeObject(new Date());
         out.writeObject(list);

         out.flush();
         out.close();
         file.close();

         System.out.println("write!");
        
         DeSerializeSample.main(new String[] {""});
     }
     static class Hoge implements Serializable {
         /**    default UID */
         private static final long serialVersionUID = 1L;
         String hoge;
         public Hoge(String hoge) {
             this.hoge = hoge;
         }
         public String getHoge() {
             return hoge;
         }
     }
 }

Deserialize処理

 package sample;
 import java.io.FileInputStream;
 import java.io.IOException;
 import java.io.ObjectInput;
 import java.io.ObjectInputStream;
 import java.util.Date;
 import java.util.List;

 import sample.SerializeSample.Hoge;

 public class DeSerializeSample {
     /**
      * @param args
      * @throws IOException
      * @throws ClassNotFoundException
      */
     public static void main(String[] args) throws IOException, ClassNotFoundException {
         FileInputStream file = new FileInputStream("C:\\hoge");
         ObjectInput input = new ObjectInputStream(file);

         Date date = (Date) input.readObject();
         List<Hoge> list = (List) input.readObject();
         input.close();

         file.close();
         System.out.println(date);
        
         for(Hoge bean : list) {
             System.out.println(bean.getHoge());
         }
     }
 }
