Instructions Overview We have been working on replicating the immutable Java String class (MyString class). In this assignment, you will provide two different versions that replicate the mutable Java StringBuilder class. Both classes will provide all the methods specified by the MyStringBuilder interface, including the length, charAt, and toString methods supported by the MyString class we implemented in class. Both classes will add a constructor that takes a MyString object as a parameter. Additionally, they will implement the attached MyStringBuilder interface. MyStringBuilderArray class You can start the MyStringBuilderArray class which inherits from the MyString class we've been working on in class. Make the instance variable characters in the parent class (MyString) from private to protected to facilitate the access to the variable in the child class (MyStringBuilderArray). Complete the implementation of all the methods appropriately. MyStringBuilderList class You can start the MyStringBuilderList class from scratch, and make sure that it implements the MyStringBuilder interface. Unlike MyStringBuilderArray class, MyStringBuilderList class will use a List object as an instance variable to store characters. Complete the implementation of all the methods appropriately. Test program Write a Java program MyStringBuilderTest to test your classes from above according. Good test programs will test edge cases as well as if proper exceptions are thrown in case of errors. Make sure you call all the methods you implemented and comment what the expected outcomes are for each method call. Starting Point Download and add the MyStringBuilder interface to our existing MyString Java project. Create the new classes: MyStringBuilderArray and MyStringBuilderList according to the specifications above. Complete all the methods to perform the necessary operations. Requirements You should use classes, objects, methods, inheritance, and interface appropriately. Make sure that you document classes and functions (JavaDoc documentation style) Make sure that all your instance variables are private. (unless specified otherwise)

Overview
We have been working on replicating the immutable Java String class (MyString class). In this assignment, you will provide two different versions that replicate the mutable Java StringBuilder class. Both classes will provide all the methods specified by the MyStringBuilder interface, including the length, charAt, and toString methods supported by the MyString class we implemented in class. Both classes will add a constructor that takes a MyString object as a parameter. Additionally, they will implement the attached MyStringBuilder interface.
MyStringBuilderArray class
You can start the MyStringBuilderArray class which inherits from the MyString class we've been working on in class. Make the instance variable characters in the parent class (MyString) from private to protected to facilitate the access to the variable in the child class (MyStringBuilderArray).
Complete the implementation of all the methods appropriately.
MyStringBuilderList class
You can start the MyStringBuilderList class from scratch, and make sure that it implements the MyStringBuilder interface. Unlike MyStringBuilderArray class, MyStringBuilderList class will use a List object as an instance variable to store characters.
Complete the implementation of all the methods appropriately.
Test program
Write a Java program MyStringBuilderTest to test your classes from above according. Good test programs will test edge cases as well as if proper exceptions are thrown in case of errors. Make sure you call all the methods you implemented and comment what the expected outcomes are for each method call.
Starting Point
- Download and add the MyStringBuilder interface to our existing MyString Java project.
- Create the new classes: MyStringBuilderArray and MyStringBuilderList according to the specifications above.
- Complete all the methods to perform the necessary operations.
Requirements
- You should use classes, objects, methods, inheritance, and interface appropriately.
- Make sure that you document classes and functions (JavaDoc documentation style)
- Make sure that all your instance variables are private. (unless specified otherwise)
