write and submit VehicleSerializable.java

The vehicle serializable will be a code similar to the following:

// Java code for serialization and deserialization // of a Java object import java.io.*; class Demo implements java.io.Serializable { public int a; public String b; // Default constructor public Demo(int a, String b) { this.a = a; this.b = b; } } class Test { public static void main(String[] args) { Demo object = new Demo(1, "geeksforgeeks"); String filename = "file.ser"; // Serialization try { //Saving of object in a file FileOutputStream file = new FileOutputStream(filename); ObjectOutputStream out = new ObjectOutputStream(file); // Method for serialization of object out.writeObject(object); out.close(); file.close(); System.out.println("Object has been serialized"); } catch(IOException ex) { System.out.println("IOException is caught"); } Demo object1 = null; // Deserialization try { // Reading the object from a file FileInputStream file = new FileInputStream(filename); ObjectInputStream in = new ObjectInputStream(file); // Method for deserialization of object object1 = (Demo)in.readObject(); in.close(); file.close(); System.out.println("Object has been deserialized "); System.out.println("a = " + object1.a); System.out.println("b = " + object1.b); } catch(IOException ex) { System.out.println("IOException is caught"); } catch(ClassNotFoundException ex) { System.out.println("ClassNotFoundException is caught"); } } }

copy and submit fig 17.18 ReadSequentialFile.java, with the following modifications: (1) change it to work with VehicleSerializable.java (2) change lines 43-45 to instead call VehicleSerializable display() method. (3) The input file name on line 21 will be vehicle.ser

Code below needs to be modified with the democode above so that they work together.

The code below tests both programs above.
