Screen shot please
Can you use it in a scanner so i can copy paste please. Part 1 A regular triangle is one for which all sides are congruent and all interior angles. Create a class RegularTriangle with a field side (int) Create a constructor which accepts an int parameter and will assign the parameter to field side Create assessor and mutator for this class Create a method getPerimeter() which should return 3*side; Part 2 in the constructor, add a logic that if the input parameter is less than 5 then set the side to 5, if it is >10 then set the side to 10, otherwise set the side to the input value. Screenshot final output
#this is a python programtopic: operation overloading, Encapsulation Please find the attached image
Create a VisualCounter class that supports both increment and decrement operations. Take the constructor inputs N and max, where N indicates the maximum number of operations and max specifies the maximum absolute value for the counter. Create a plot that shows the value of the counter each time its tally changes as a side effect.
Create a class called SquareTester that will create a Square object. Print out the toString method with the object as your receiver. Print out the perimeter using the getArea method and the object as your receiver. public class SquareTester { public static void main(String{}args) { //create your Square object with any value as your argument //print the toString method //print the area of the square on a new line -ex: “The area is: 64” } }
Using JAVASCRIPT write an object prototype for a Person that has a name and age, has a printInfo method, and also has a method that increments the persons age by 1 each time the method is called. Create two people using the 'new' keyword, and print both of their infos and increment one persons age by 3 years. Use an arrow function for both methods */ // Create our Person Prototype // Use an arrow to create the printInfo method // Create another arrow function for the addAge method that takes a single parameter // Adding to the age
Create a Class Pet with the following data members Identification: String species : String (e.g. cat, dog, fish etc)  breed: String  Age (in days): int  Weight: float  Dead: boolean 1. Provide a constructor with parameters for all instance variables. 2. Provide getters for all and setters for only breed, and weight 3. Provide a method growOld() that increases the age of the pet by one day. A dead pet wont grow old 4. Provide a method growHealthy(float w) that increases the weight of the pet by the given amount w. A dead pet cannot grow healthy. 5. Provide a method fallSick(float w) that reduces the weight of the pet by the given amount. The least weight a pet can have is 0 which will mean that the pet has died. If the value of weigh is 10 kg and the method is called with an argument of 11 kg then you will set it to 0 and set the dead to an appropriate value to mark the death of the pet 6. Provide a toString method that shows an appropriate well formatted string…
Problem: Bugs are simple creatures that only know how to walk towards other bugs. Bugs maintain information about their (x, y) position; by which it can tell if they are standing next to other bugs. Watch the following video: bug movement. Create a java project that simulate bugs movement. You need to write a class “Bug" that models a bug moving along a straight line and it can turn to change its direction counterclockwise (i.e. 90 degree to the left; north → west → south → east → north). In each move, its position changes by one unit in the current direction. Details of the "Bug" class is described below. Your simulator should read information of an unknown number of “Bug" objects from an input file called “Bugs.txt". Each line represents a bug and the initial position and facing direction of this particular bug. Keeping the first bug position as a reference the simulator should move the second bug next to the first bug forming a cluster and its final position and direction should be…
Write code for a Java class Rectangle with the following fields and methods: Rectangle width : double - height : double - area : double + perimeter : double + diagonal : double +Rectangle () : void + setRectangle (double w, double h) : void + printRectangle () : void + changeWidth (double w) : void + changeHeight (double h) : void static computeDiagonal (double w, double h) : double Fields Methods Methods: Rectangle: Constructor, creates a rectangle with width and height equal to zero. setRectangle: Sets the width and height equal to the two parameters. Computes and stores the rectangle area, perimeter and diagonal. printRectangle: Prints the width, height, area, perimeter and diagonal of the rectangle with labels. All values are printed with a maximum of 2 digits after the decimal. Extra Credit (+5): Include a visual representation of the rectangle: ##### #3 # #### Extra Credit (+2): Visual representation works with length of 1 for height and/or width. changeWidth: Changes the width…
