Question

In this lab we will deserialize a Java object that contains data about a movie. The serialized object contains a String containing the movie's title, a String containing the name of the movie's director, and an int containing the year the movie was released.

Import the attached Movie.java file into an Eclipse project. Make sure the Movie class is in a package named lab6.Next, download the file in the "Lab 6 serialized file" folder. Finally, create a class that contains a main method that deserializes this file and displays the title, director, and year using the Movie class's getter methods.

Upload the source file with the main method that deserializes the file, and upload a text file that contains the title, director, and year from the serialized file.

Explanation / Answer

Movie.java

import java.io.Serializable;

public class Movie implements Serializable {

private String title;

private String director;

private int year;

public Movie(String title, String director, int year) {

this.title = title;

this.director = director;

this.year = year;

}

public String getTitle() {

return title;

}

public String getDirector() {

return director;

}

public int getYear() {

return year;

}

}

Output:

Enter the Movie title :Titanic
Enter the nam eof Director :James Cameron
Enter the Year :1996
Movie Object has been serialized
Movie Object has been deserialized
Movie Name = Titanic
Director = James Cameron
Year = 1996
