Sample Output: User input is in RED. Because characters are generated randomly, the characters in your array will look different from the sample output. Please check your result according to the operations of methods but not match the sample output directly.

  Part 2: Programming (13 points) Your assignment is to create a class called CharList in a file called CharList.java. (there is no main method in this class). The class CharList has two instance variables, an array of characters and an integer variable, which keeps track of the number of characters in the array Note: the number of elements is different from the size of the array The class CharList must include the following constructor and methods. (If your class does not contain any of the following methods, points will be deducted.) Method Description of the Method The constructor instantiates an array of characters using the given size Fills array with random characters between 'a" to z Adds a character (newChar) to the arry at the specified index and shifts all the elements (after passed index) to the right by one index. If the array is full, its size will be doubled first This method is private and it doubles the size of the arra Removes the first occurrence of newChar from the public CharList (int size) ublic void randomize () public void addChar (char newChar, int index) private void increasesize () public void removeFirst (int newChar)array and shifts all the elements (after the removed one) to the left by one index. this method returns an array of twenty-six int values, each of which stores the number of occurrence of each letter contained in the "charList". For example, the first element in the Displays the array of characters. You should print 10 characters per line public int[) countLetters) stores the number of occurrences for letter 'a public String toString ) wing program stored in Assignment7.iava Save the CharList class in a file called CharList.java and use the follo which has the main method to test your class. The main function prints the menu: Menu a: Create a new list (*do this first!!) b: Print the list of characters c: Add a character to the list at specified index d: Remove a character from the list e: Count the number of letters in the list q. Quit Here is the description for each opti on: a: Creates a new list with specific size from the user and fill the list with random cahracters between a' to 'z' b: It prints the characters using the toString method c: Adds a new character to the list by asking the user for the character and the index where the character will be added d: It deletes the first occurrence of the character entered by the user e: It counts the number of occurrence of each letter 'a, to z' in the array gquit
