Question

Based on Movie package example, you will create a package about your favorite TV series and provide the plot()

Readme.txt: Explain how you apply polymorphism in your program

package Movie;

public class MovieTester {
public static void main(String[] args) {

for(int i = 1; i < 11; i++){
Movie movie = randomMovie();
System.out.println("Movie # " + i + ": " + movie.getTitle() + ", Genre: " + movie.getGenre() + '\n'
+"Plot: " + movie.plot());
}

}

public static Movie randomMovie(){
int randomNumber = (int)(Math.random() * 5) + 1; //1 and 5

System.out.println("Random number is going to be generated and it is " + randomNumber);

switch(randomNumber){
case 1: return new Borat();
case 2: return new Inception();
case 3: return new JohnWick();
case 4: return new Parasite();
case 5: return new Shrek();
}

return null;
}
}

class Movie{

private String title;
private String genre;
private String rating;
private int year;
private int length; //minute

public Movie(String title, String genre, String rating, int year, int length) {
this.title = title;
this.genre = genre;
this.rating = rating;
this.year = year;
this.length = length;
}

public String getTitle() {
return title;
}

public String getGenre() {
return genre;
}

public String getRating() {
return rating;
}

public int getYear() {
return year;
}

public int getLength() {
return length;
}

public String plot(){
return "No plot yet provided";
}
}

//Shrek, JohnWick, Inception, Borat, Parasite

class Shrek extends Movie{

public Shrek(){
super("Shrek","Animation","R",1991,120);
}
@Override
public String plot(){
return "To save Fiona.";
}

}

class JohnWick extends Movie{

public JohnWick(){
super("John Wick","Action","R",2000,120);
}

@Override
public String plot(){
return "To revenge";
}

}

class Inception extends Movie{

public Inception(){
super("Inception", "Thriller", "PG",1996, 150);
}

@Override
public String plot(){
return "To chasing.";
}

}

class Borat extends Movie{

public Borat(){
super("Borat", "Comedy", "R", 2020,120);
}

@Override
public String plot(){
return "Trying to find Pamela Anderson.";
}

}

class Parasite extends Movie{

public Parasite(){
super("Parasite", "Horror", "R", 2019, 120);
}

@Override
public String plot(){
return "About three family";
}

}

If you have any problem with the code feel free to comment. Add more tv series class accordingly.

TvSeries

package tvSeries;

public class TVSeries {
        //instance variables
        private String title;
        private String genre;
        private String rating;
        private int year;
        private int numEpisodes;
        
        //constructor
        public TVSeries(String title, String genre, String rating, int year, int numEpisodes) {
                this.title = title;
                this.genre = genre;
                this.rating = rating;
                this.year = year;
                this.numEpisodes = numEpisodes;
        }

        //all getter methods
        public String getTitle() {
                return title;
        }

        public String getGenre() {
                return genre;
        }

        public String getRating() {
                return rating;
        }

        public int getYear() {
                return year;
        }

        public int getNumEpisodes() {
                return numEpisodes;
        }
        
        //plot method
        public String plot() {
                return "no plot yet";
        }

        //toString method
        @Override
        public String toString() {
                return "Title=" + title + "\nGenre=" + genre + "\nRating=" + rating + "\nYear=" + year + "\nNumber of Episodes="
                                + numEpisodes;
        }
        
}

BigBangTheory

package tvSeries;

public class BigBangTheory extends TVSeries {
        //initializing the TvSeries constructor
        public BigBangTheory() {
                super("The Big Bang Theory", "Comedy", "8.3", 2007, 279);
        }
        
        //giving the plot
        @Override
        public String plot() {
                return "Nerds learning to interact with girls";
        }
}

BreakingBad

package tvSeries;

public class BreakingBad extends TVSeries {

        public BreakingBad() {
                super("Breaking Bad", "Crime", "9.6", 2008, 62);
        }
        
        @Override
        public String plot() {
                return "A chemistry teacher becomes a drug lord";
        }

}

TvSeriesTester

package tvSeries;

public class TVSeriesTester {
        public static void main(String[] args) {
                //using polymorphism 
                TVSeries bbt = new BigBangTheory();
                TVSeries bb = new BreakingBad();
                
                //showing result
                System.out.println(bbt);
                System.out.println("Plot= "+bbt.plot());
                System.out.println("\n"+bb);
                System.out.println("Plot= "+bb.plot());
        }
}

Output
