- : A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate. Also, write a test program to test the various operations on the point.PLEASE USE 2 CLASSES (you do not have to answer quickly please take your time) In the Game of 21, a player is dealt two cards from a deck of playing cards and then optionally givena third card. The player closest to 21 points without going over is the winner. Use object-orienteddevelopment to create a Game of 21 application that allows the user to play the Game of 21 against thecomputer. The Game of 21 application and its objects should:• Deal a card from a deck of playing cards by generating a random number between 1and 13. A 1 corresponds to an Ace, numbers 2 through 10 correspond to those cards,and 11 through 13 corresponds to Jack, Queen, and King. The Jack, Queen, and Kinghave a value of 10 in the Game of 21. An Ace can have a value of either 1 or 11.• Allow the player to stay with two cards or be given a third card.• Announce the winner.• Play rounds until the player says to stopWhen you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class.
