The document defines classes for different types of productions - Production, Film, Play, and Musical. Production is the parent class that defines common properties like title, director, writer. Child classes like Film add properties specific to that type - box office gross for Film. The main method creates objects of each type and prints their details.

1. Production.java
public class Production {
//Declaring instance variables
private String title;
private String director;
private String writer;
//Parameterized constructor
public Production(String title, String director, String writer) {
super();
this.title = title;
this.director = director;
this.writer = writer;
}
//Setters and getters.
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDirector() {
return director;
}
public void setDirector(String director) {
this.director = director;
}
public String getWriter() {
return writer;
}
public void setWriter(String writer) {
this.writer = writer;
}

2. //display() method which displays the Instance variable values
public void display()
{
System.out.println("Title: " + this.title);
System.out.println("Director: " + this.director);
System.out.println("Writer: " + this.writer);
}
//toString() method is used to display the contents of an object
@Override
public String toString() {
return "Title :" + title + " Director :" + director
+ " Writer :" + writer;
}
}

}
//Setters and getters.
public int getBoxOfficeGross() {

public void setBoxOfficeGross(int boxOfficeGross) {

//display() method which displays the Instance variable values

}
//toString() method is used to display the contents of an object

}
//Setters and getters.
public int getPerformances() {
