Question

\\ this is the code i need help to get this part working the rest works but this and im not sure what is missing or how to make it work. this is what they asking for to do and there is two errors the ones shown in the pictures this is all the information I have from zybooks\\

Q3. (54 Points) Complete a public class to represent a Movie as described below.

(a-e 4 pts each) (f-h 8 pts each) (i, j 5 pts each)

1. Create the following private member variables

Data Type	String	int	boolean	int	String [ ]
Variable Name	movieName	numMinutes	isKidFriendly	numCastMembers	castMembers

2. Create the default constructor so it will initialize the variables to the following default values.

Attribute	movieName	numMinutes	isKidFriendly	numCastMembers	castMembers
Default Value	“Flick”	0	false	0	length of 10

3. Create the fully overloaded constructor that accepts all variables as input parameters, except numCastMembers which is calculated based on the number of cast members in the castMembers array. Movie( String movieName, int numMinutes, boolean isKidFriendly, String[] castMembers )

4. Create setter methods for the numMinutes, movieName, and isKidFriendly variables.

5. Create getter methods for all the variables. Make sure that the getter for castMembers returns a copy of the array.

6. Create a method named replaceCastMember that allows the name of a castMember at an index in the castMembers array to be changed. The method should take in 2 arguments, the int index and the String castMemberName. The method should return a true if the replacement was successful, false otherwise. (Note: Only update the castMember in the array if the index is valid)

public boolean replaceCastMember(int index, String castMemberName)

7. Create a public method that determines the equality of two String arrays and returns a boolean, by comparing the value at each index location. Return true if all elements of both arrays match, return false if there is any mismatch. Also, if only one of the provided arrays is null, the method returns false, if both provided arrays are null, the method returns true. (Note: this method will be used by the equals method in part h)

Hint: Both arrays should have the same number of items, and the items at each index must match, ignoring case.

public boolean doArraysMatch(String [] arr1, String [] arr2)

8. Create a method named getCastMemberNamesAsString that gets the contents of the array of castMembers as a comma separated String. Hint: no trailing comma allowed

Note: If there are no cast members in the array return “none”

9. Create the toString() method for the Movie object such that it returns a well structured sentence containing the information for all the object’s variables.

(Note: Use the helper method getCastMemberNamesAsString created previously)

Example of the formatted String returned:

“Movie: [ Minutes 142 | Movie Name: The Shawshank Redemption | not kid friendly | Number of Cast Members: 3 | Cast Members: Tim Robbins, Morgan Freeman, Bob Gunton ]”

“Movie: [ Minutes 090 | Movie Name: Aladdin | is kid friendly | Number of Cast Members: 4 | Cast Members: Scott Weigner, Robin Williams, Linda Larkin, Jonathan Freeman ]”

10. Create the equals(Object o) method for the Movie object, such that it returns true if the values of all the members of both the calling object and the passed in object match. Return false if any values do not match. (Note: Use the helper method named doArraysMatch created previously)
