(Game: ATM machine) Use the Account class created in our previous Lab Exercise to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . ., 9, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.

(Geometry: MyRectangle2D class) Define the MyRectangle2D class that contains: Two double data fields named x and y that specify the center of the rectangle with getter and setter methods. (Assume the rectangle sides are parallel to the x- or y-axis.) The data fields width and height with getter and setter methods. A no-arg constructor that creates a default rectangle with (0, 0) for (x, y) and 1 for both width and height. A Constructor that creates a rectangle with the specified x, y, width, and height. A method getArea() that returns the area of the rectangle. A method getPerimeter() that returns the perimeter of the rectangle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this rectangle (see Figure 10.24a ). A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle (see Figure 10.24b ). A method overlaps(MyRectangle2D r) that returns true if the specified rectangle overlaps with this…

(Written in Java or Python) Write a program that allows a user to select 3 points on a graphics panel. Then, draw a triangle using these 3 points. Allow the user to specify a number of random points to be generated inside of the triangle. For each random point that is within the boundaries of the triangle draw a small dot at each of the points that are halfway between the randomly generated point and each vertex of the triangle. Do not draw the randomly generated point. Allow the user to repeat the process without removing the old dots. Allow the user to clear the screen.
