Program Plan Intro

Print Christmas tree

Program plan:

Import the required package.

Create a class “ChristmasTree”,

Define the method “main()”,

Declare the necessary variables.

Create “Scanner” object.

Prompt the user to enter the number of segments and height of the Christmas tree.

Get the number of segments and height from the user.

Print new line.

Assign the number of segments and height to the variable “m” and “n” respectively.

Set the starting row value to “1”.

Create “for” loop to iterate till number of segments using “i”,

Create “for” loop to iterate till the height of the tree using “j”,

Execute “while” loop,

Print space.

Increment counter variable.

Create loop whenever the number of rows greater than the “i” value,

Print space.

Create loop whenever the “j” value is less than or equal to “i” value,

Print “”.

Create loop using the variable “k” whenever the value is less than “i”,

Print “”.

Print new line.

Increment the starting row.

Increment the number of rows.

Print stem of the tree as follows,

Create loop till the value get from dividing the (number of rowsnumber of segments-1) by “2”,

Print space.

Print “”.

Create loop till the value get from dividing the (number of rowsnumber of segments-1) by “2”,

Please answer JAVA OOP problem below: Assume you have three data definition classes, Person, Student and Faculty. The Student and Faculty classes extend Person. Given the code snippet below, in Java, complete the method determinePersonTypeCount to print out how many Student and Faculty objects exist within the Person array. You may assume that each object within the Person[] is either referencing a Student or Faculty object. public static void determinePersonTypeCount(Person[] people){ // Place your code here }

Please answer JAVA OOP question below: Consider the following relationship diagram between the Game and VideoGame data defintion classes. Game has a constructor that takes in two parameters, title (String) and cost (double). The VideoGame constructor has an additional parameter, genre (String). In Java, efficiently write the constructors needed within the Game class and VideoGame classes. Hint: Remember to think about the appropriate validation

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items. //Implementation Class public class ShoppingCart{ public static void main(String[] args){ final int MAX_ITEM = 50; Item cart = new Item[MAX_ITEM]; addItem(cart); // populate the item array printItem(cart); } } Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context? i) Polymorphism ii) Method Overloading iii) Method Overriding iv) Dynamic Binding v) Abstract Class Explain, using course terminology, how you would use any of the above concepts to model the given scenario.
