Java- Save object data to a file [closed]

Answer 1

An example of how to serialize an object:

public static void writeToFile(File path, Database data)
{
    try(ObjectOutputStream write= new ObjectOutputStream (new FileOutputStream(path)))
    {
        write.writeObject(data);
    }
    catch(NotSerializableException nse)
    {
        //do something
    }
    catch(IOException eio)
    {
        //do something
    }
}


public static Object readFromFile(File path)
{
    Object data = null;

    try(ObjectInputStream inFile = new ObjectInputStream(new FileInputStream(path)))
    {
        data = inFile.readObject();
        return data;
    }
    catch(ClassNotFoundException cnfe)
    {
        //do something
    }
    catch(FileNotFoundException fnfe)
    {
        //do something
    }
    catch(IOException e)
    {
        //do something
    }
    return data;
}
