序列化與反序列化

Animal

public class Animal implements Serializable {
public String name;
 public String breed;
 public String gender;
 public int weight;

}

Main

public class Main {

 public static void main(String[] arugs) {
 Animal animal=new Animal();
 animal.name="Tom";
 animal.breed="Cat";
 animal.gender="Male";
 animal.weight=10;
 Animal a=null;
 try{
 FileOutputStream outputStream=new FileOutputStream("animal.ser");
 ObjectOutputStream out=new ObjectOutputStream(outputStream);
 out.writeObject(animal);
 out.close();
 outputStream.close();
 System.out.printf("Serialized data is saved in animal.ser");
 FileInputStream inputStream=new FileInputStream("animal.ser");
 ObjectInputStream in=new ObjectInputStream(inputStream);
 a=(Animal) in.readObject();
 in.close();
 inputStream.close();
 }catch (IOException e){
 System.out.println("outPutStream filed");
 }catch (ClassNotFoundException e){
 System.out.println("not found object");
 }

 System.out.println("\n"+animal.name+" "+animal.breed+" "+animal.gender+" "+animal.weight);

 }

}

別忘了新建animal.ser文件。控制檯輸出結果:Serialized data is saved in animal.ser             Tom Cat Male 10
