Java基础之序列化对象——反序列化对象（DeserializeObjects）

控制台程序，使用如下代码能读入包含Junk对象的文件：

 import java.io.*;
 import java.nio.file.*;

 class DeserializeObjects {
   public static void main(String args[]) {
     Path file = Paths.get(System.getProperty("user.home")).resolve("Beginning Java Struff").resolve("JunkObjects.bin");
     if(Files.notExists(file)) {
       System.out.printf("\nFile %s does not exist.", file);
       System.exit(1);
     }

     int objectCount = 0;                                               // Number of objects read
     try (ObjectInputStream objectIn = new ObjectInputStream(new BufferedInputStream(Files.newInputStream(file)))){
        // Read from the stream until we hit the end
        Junk object = null;                                             // Stores an object reference
        while(true) {
         object = (Junk)objectIn.readObject();                          // Read an object
         ++objectCount;                                                 // Increment the count
         System.out.println(object);                                    // Output the object
       }

     } catch(EOFException e) {                                          // This will execute when we reach EOF
       System.out.println("EOF reached. "+ objectCount + " objects read.");

     } catch(IOException|ClassNotFoundException e) {
       e.printStackTrace();
     }
   }
 }
