How do I fix the error Java?
Error ---------- Movie.toString() returns:
Movie: [ Minutes 142 | Movie Name:The Shawshank Redemption | not kid friendly | Number of Cast Members: 3 | Cast Members: ]
instead of:
Movie: [ Minutes 142 | Movie Name: The Shawshank Redemption | not kid friendly | Number of Cast Members: 3 | Cast Members: Tim Robins, Morgan Freeman, Bob Guton ]
without bringing this error
Error ---------- Exception occurred while calling Movie.toString()
