Chapter 1.2, Problem 13STQ
Program Plan Intro
Methods:
A collection of statements which are formed together to perform an operation is called as methods.
- • The main advantage of using method is reusability of code and reduces the size of the program, because a method can be called for multiple numbers of times.

Suppose you have a class named Candy imported and you instantiate an object named reeses. Also, suppose that the Candy class has a method named getFlavor, which requires no arguments.
Type the line of code that would run the method getFlavor on the reeses object.
(In python)
Write a program that simulates the Magic 8 Ball game. The class should have a method that returns an answer at random. Test your class by outputting the answer several times.
In Public Class, create a static void method called Info_AHW that takes 3 parameters - an int and two double. When the method is called, we pass along the age (A), then the height (H), and then the weight (W), which is used inside the method to print the person's age, then the height and then the weight. NOTE: The Print out must follow the output below
Afterward, in the main method, get the User input using the Scanner class to get the three input - the int age, the double height and the double weight.
Then, call your Info_AHW method and pass your arguments (age, height, weight) into that method.
Hint:
When getting the int input, use -> sc.nextInt();
When getting the double input, use -> nextDouble();
Input:
5 65.5 70.2
Output:
Your age is 5 ; your height is 65.5 ; and your weight is 70.2
Note:
-There is a single space between every word and semicolon
-There is no space at the end

(b) Your Account class should provide three class variables: - `interest_rate` set to 0.05 (5%) - `overdraft_limit` set to 500 (dollars), and - `overdraft_charge` set to 50 (dollars). These are values common to all accounts at this bank (i.e. all instances of this class). (c) Additionally, the Account class should create two instance variables: - `account_number` of the customer and - `balance` which is set to 0 dollars (it’s a new, empty account) These are values unique to each Account instance.
