Define an inner member class named DownRightpath which defines a moving path. The MovingPath is an abstract inner class which contains an abstract method. The DownRightPath class should extend the MovingPath and implement the move () method. Themember class contains the following:• A private int data field named interval which defines the number of intervals. The default value is 0.A private boolean data field named isDownward which defines the moving direction. The default value is true.• A constructor which takes two integers as parameters and constructs a moving path with the given deltax and deltay values.• A method named move () which moves shapes. The method moves the outer class's shape downward by deltaY pixels for 10 intervals, then move the shape to the right by deltax for 10 intervals and so on. If the bottom of the shape reaches the bottomboundary, the shape will then re-start at the top position (i.e. y=0). If the right hand corner of the shape reaches the right boundary, the shape will then re-start at the left position (i.e. x=0).Write the inner member class definition ONLY in the answer box below assuming that the abstract superclass Shape and the RectangleShape subclass are given. Note - keep a copy of your solution to this task because you will be extending it step by step insubsequent tasks.For example:TestResultRectangleshape ri = new Rectangleshape (18, 28, 50,100,500,68e, color.orange, PathType.DOWNRIGHT);for (int i=0; i<11; i++) {Color: java.awt.color[r=255,g=200, b=e]Rectangle[x=10,y=25, width=5e, height=100]Color: java.awt.color[r=255,g-200,b=e]Rectangle[x=10,y=30, width=5e, height=100]Color: java.awt.color[r=255,g-200, b=e]Rectangle[x=10,y=35, width=50, height=100]Color: java.awt.color[r=255,g-200, b=e]Rectangle[x=10,y=48, width=5e, height=100]color: java.awt.color[r=255,g=200, b=0]r1.move(); r1.draw(painter);Rectangle[x=10,y=45, width=5e, height=100]color: java.awt.color[r=255,g=200, b=0]Rectangle[x=10,y=5e, width=5e, height=100]color: java.awt.color[r=255,g=200, b=0]Rectangle[x=10,y=55, width=5e, height=100]Color: java.awt.color[r=255,g-200, b=e]Rectangle[x=18,y=68, width=50, height=100]Color: java.awt.color[r=255,g-2e0, b=e]Rectangle[x=18,y=65, width=5e, height=100]Color: java.awt.color[r=255,g-200, b=e]Rectangle[x=10,y=7e, width=5e, height=100]Color: java.awt.color[r=255,g-200,b=e]Rectangle[x=15,y=7e, width=5e, height=100]Rectangleshape ri = new Rectangleshape(445,100, 50,100,500, 600, Color.orange, PathType.DOWNRIGHT); color: java.awt.color[r=255,g-200,b=e]on (int i OLi 10L iuDostao-leLy ArA v 150 i dth re baigh+ 1001

Create a class POINT to represent a point in Cartesian coordinate system Chooseappropriate data members. Provide member functions: Default constructor Parameterized constructor Input  Output Distance( returns the distance between two POINT objects, the function takes one objectas an input) isZero(determines if a point is the center) Midlepoint(returns the middle point , takes one object as an input and returns the answerin a POINT object) isEqualTo (compare two POINTs) isGreaterThan (compares two POINT in terms of the distance from the center )o Above two function takes one POINT object as an argument and returns true ifthe condition is satisfied and false otherwise. plz solve it with C++.
Design a new Account class as follows:■■ Add a new data field name of the String type to store the name of thecustomer.■■ Add a new constructor that constructs an account with the specified name, id,and balance.■■ Add a new data field named transactions whose type is ArrayList thatstores the transaction for the accounts. Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account. Print an account summarythat shows the account holder name, interest rate, balance, and all transactions.

The Point2D should store an x and y coordinate pair, and will be used to build a new class via class composition. A Point2D has a x and a y, while a LineSegment has a start point and an end point (both of which are represented as Point2Ds). class Invariants The start and end points of a line segment should never be null Initialize these to the origin instead.

build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…

User-defined Class:You will design and implement your own data class. The class will store data that has been read asuser input from the keyboard (see Getting Input below), and provide necessary operations. As thedata stored relates to monetary change, the class should be named Change. The class requires atleast 2 instance variables for the name of a person and the coin change amount to be given to thatperson. You may also wish to use 4 instance variables to represent amounts for each of the 4 coindenominations (see Client Class below). There should be no need for more than these instancevariables. However, if you wish to use more instance variables, you must provide legitimatejustification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriateget and set methods for client usage. Other…
