- Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…arrow_forwardCreate a Point class to hold x and y values for a point.

- AVA code OVERVI EW This is a review exercise, so the primary goal of the exercise is to get your mind working and in the correct space.In this activity you will create a imaginary grid of locations that goes from −?≤?≤?, −?≤?≤?, with the coordinate (0,0) being "home". On this grid you will keep track of various animal objects as they move around the grid. Make sure that all animals stay within that grid at all timesincluding when they are created. Zwill be the map size and will control the highest number allowed on themap before wraping around.

- Please help me with this Java Labarrow_forwardFor this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }arrow_forwardCoupling is the amount two methods or classes know about one another.

- Create a program that will count the number of numeric characters in an input string. The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class. Sample Output: Enter a string: Hello 123 Number of numeric characters: 3arrow_forwardAssume that we have a Button object named btnPrint, and a method named print().

A rational number consists of a numerator and a denominator (which cannot be 0). Rational numbers also have the ability to be displayed in an original form, decimal form or reduced form. You are going to be completing various object methods to perform the tasks previously list. You are to begin with the Rational Class and RationalTest classes provided. Make all modifications outlined in the point values below. Pay close attention to the names of the attributes, methods and return values. You are given starter files and the test files necessary. Only modify class Rational and keep the function headers provided to you for all of Part 1. You will need to add your own methods for Part 2. Part 1a This version requires that you complete the constructor, getOriginal(), and getDecimal() methods of class Rational. Constructor: at this stage…arrow_forward
