Question

Java Programming

Create a program named MovieTest

The program will create 10 Movie objects and place them in an array or ArrayList of type Movie.

The program must do the following (all in main):

• Create an array or ArrayList of type Movie.
• Use the data in the text file that is in the download for the Movie file to create 10 Movie objects. Store the 10 Movie objects in the array or ArrayList. You MUST use the date in the text file to create the objects.
• Use an enhanced for loop to display all movies in the array or ArrayList. Call the toString method on each Movie object and display the String returned from toString..
• Search the array or ArrayList for the highest and lowest rated movies and display them, clearly labeled.
• ALL OUTPUT MUST BE CLEARLY LABELED. Use the command prompt window (terminal).
