Program Plan Intro
Occurrences of a specified character
Program Plan:
- Import necessary stream packages into program.
- Define the class named “Main”.
- Define main method.
- Initialize the object “obj” for “Scanner” class.
- Prompt and get the input value from user.
- Split the individual character and store the result in “ch” variable.
- Call the “count()” to count number occurrences of specified character.
- Print the resultant value on screen.
- Define the method “count()” which takes “str” and “a” as parameters.
- Call the “toCharacterArray()” method and return the result.
- Define the method “toCharacterArray()” which takes array list “list” as parameter.
- Declare the character variable “ans” in type of character.
- Using “for” loop, assign all list values into “ans[]” variable.
- Return the value of “ans”.
- Define main method.

(Class Average: Writing a Gradebook Dictionary to a JSON File)
Reimplement Exercise 9.3 using the json module to write the student information to the file in JSON format. For this exercise, create a dictionary of student data in the following format:
gradebook_dict = {'students': [student1dictionary, student2dictionary, ...]}
Each dictionary in the list represents one student and contains the keys 'first_name', 'last_name', 'exam1', 'exam2' and 'exam3', which map to the values representing each student’s first name (string), last name (string) and three exam scores (integers).
Output the gradebook_dict in JSON format to the file grades.json.
