В любое время, когда я пытаюсь сериализовать файл, я получаю ошибку: FileNotFound. Не знаю, почему. Вот мой код FileHelper:
package org.stocktwits.helper;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutput;
import java.io.ObjectOutputStream;
import java.util.ArrayList;
import org.stocktwits.model.Quote;
public class FileHelper {
// Returns the contents of the file in a byte array.
public static byte[] getBytesFromFile(File file) throws IOException {
InputStream is = new FileInputStream(file);
// Get the size of the file
long length = file.length();
// You cannot create an array using a long type.
// It needs to be an int type.
// Before converting to an int type, check
// to ensure that file is not larger than Integer.MAX_VALUE.
if (length > Integer.MAX_VALUE) {
// File is too large
}
// Create the byte array to hold the data
byte[] bytes = new byte[(int)length];
// Read in the bytes
int offset = 0;
int numRead = 0;
while (offset < bytes.length
&& (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
offset += numRead;
}
// Ensure all the bytes have been read in
if (offset < bytes.length) {
throw new IOException("Could not completely read file "+file.getName());
}
// Close the input stream and return bytes
is.close();
return bytes;
}
public static void serializeQuotes(ArrayList<Quote> quotes){
try {
// Serialize to a file
ObjectOutput out = new ObjectOutputStream(new FileOutputStream("quotes.ser"));
out.writeObject(quotes);
out.close();
// Serialize to a byte array
ByteArrayOutputStream bos = new ByteArrayOutputStream() ;
out = new ObjectOutputStream(bos) ;
out.writeObject(quotes);
out.close();
// Get the bytes of the serialized object
//byte[] buf = bos.toByteArray();
} catch (IOException e) {
System.out.println(e);
}
}
@SuppressWarnings("unchecked")
public static void deserializeQuotes(ArrayList<Quote> quotes){
try {
// Deserialize from a file
File file = new File("quotes.ser");
ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
// Deserialize the object
quotes = (ArrayList<Quote>) in.readObject();
in.close();
// Get some byte array data
byte[] bytes = FileHelper.getBytesFromFile(file);
// see Reading a File into a Byte Array for the implementation of this method
// Deserialize from a byte array
in = new ObjectInputStream(new ByteArrayInputStream(bytes));
quotes = (ArrayList<Quote>) in.readObject();
in.close();
} catch (ClassNotFoundException e) {
System.out.println(e);
} catch (IOException e) {
System.out.println(e);
}
}
