import java.io.*;
class movieMagic
{
int year;
String title;
float rating;

movieMagic() // default constructor
{
year = 0;
rating = 0.0f; // notice the ‘f’
title = “”;
}

void accept() throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print(“Enter the title of the movie : “);
title = br.readLine();
System.out.print(“Enter the year of its release : “);
year = Integer.parseInt(br.readLine());
System.out.print(“Enter the movie rating : “);
rating = Float.parseFloat(br.readLine());
}

void display()
{
System.out.println(“The title of the movie is : “+title);
if( rating >= 0.0 && rating <= 2.0 ) { System.out.println("The movie was a Flop"); } else if( rating >= 2.1 && rating <= 3.4 ) { System.out.println("The movie was a Semi-hit"); } else if( rating >= 3.5 && rating <= 4.5 ) { System.out.println("The movie was a Hit"); } else if( rating >= 4.6 && rating <= 5.0 ) { System.out.println("The movie was a Super Hit"); } else { System.out.println("Enter a valid movie rating in between 0.0 and 5.0"); } } public static void main(String args[]) throws IOException { movieMagic ob = new movieMagic(); // creating object of the class movieMagic ob.accept(); ob.display(); } }[/java]
