- Slide Type Slide • Exercise # 1: Define a class Point that represents a point in 2 – D plane. The point has x and y coordinates. Define the following: • A constructor to initialize the x, y coordinates. • A method translate(self, dx,dy) to translate the point object dx , and dy units in x and y directions, respectively. • A method distanceTo (self, point2) to return the distance between the point referenced by self and point2. • getX(self) to return the value of x coordinate. • getY(self) to return the value of y coordinate Test the above class by: • Creating 2 point objects; one with (3,5) as x,y coordinates; the second with (-10,30) as x,y coordinates. • Move the first point 5.5 units in x direction and -12.5 units in y direction using translate method • Find the distance between the 2 points in their current location using distance To method A Sample output resulting from running the above test class is shown below new coordinates of point1= (8.5 , -7.5) Coordinates of point 2 =…ClockPane.java, to add the animationinto this class and add two methods start() and stop() to start and stop theclock, respectively. Write a program that lets the user control the clock with theStart and Stop buttons, as shown in Figure a .Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…
- Class RightTriangle Represents a right triangle by the length of each of its two legs Includes the default and overloaded constructor, methods to set the length of each of the two legs, amethod to get the area, a method to scale the size of the triangle, a method to invert the triangle(swap the lengths of its two legs), and a method to print its dimensions.Class TestRightTriangle Creates and initializes two triangles. Calls the various associated methods to set its size, compute its area, scale its size, invert, and print itsdimensions.You are required to implement both classes according to the requirements specified in the commentsdisplayed in the .java files. The following is an example of possible output:triangle1 dimensions: 6.0 3.5triangle1 area: 10.5triangle2 dimensions: 3.0 4.0triangle2 area: 6.0triangle1 dimensions: 18.0 10.5triangle2 dimensions: 5.5 6.5triangle1 dimensions: 4.5 2.625triangle1 dimensions after invert: 2.625 4.5A few details: Do NOT modify any of the code…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…Climber is a class that has been defined, and the variable cat refers to a Climber instance. With an argument of 4, call the method stairs on the instance referred to by cat.This is a python script.
- Design and implement the class Day that implements the day of the week in a program. The program should be able to perform the following operations on an object of the type Day: Set the day. Print the day. Return the day. Return the next day. Return the previous day. Add a comment with your full name in it in any part of the program.Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, design a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. very basic Algorithm in pseudocode. Use fictitious information.Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
- 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” } }Assume the following Window class has been defined: public class Window { private int width; private int height; private int xPos; private int yPos; // The rest of the class is not shown… } Define an equals method for the Window class. Two Window objects will be considered equal if their width fields are equal, their height fields are equal, their xPos fields are equal, and their yPos fields are equal.Hello.
