Question

Use the text file with the following data:

Movie Name, duration

You will be given a Movie class that will contain the 2 fields, a constructor to initialize the 2 fields, and a toString method. It will also have the appropriate getters and setters in the Movie class.

You will need to create a Driver class that will read the input file. You will create a Movie object per record in the file, and store the Movie object in an array of Movies. The array of Movies will be created as a static global variable, before the main method.

Write a method in the driver class that will find the movie with the longest duration and the shortest duration. The method should also add up all the movie durations, so that after the loop, you can calculate the average duration of all movies.

Output:

The Godfather has the highest duration 175
Duck Soup has the lowest duration 68
The Average duration of all movies is 119.91
