Define a class called Counter. An object of this class is used to count things, so it records a count that is a nonnegative whole number. Include methods to set the counter to 0, to increase the count by 1, and to decrease the count by 1. Be sure that no method allows the value of the counter to become negative. Also include an accessor method that returns the current count value, as well as a method that displays the count on the screen. Do not define an input method. The only method that can set the counter is the one that sets it to zero. Write a

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 =…arrow_forwardJAVA Write a class that calculates add, subtraction, and multiplication. The class should include the following methods: Constructor : initialize all values to 0 getAsk() : Ask users to input two integer numbers. This method calls Distribute() method. Distribute() : Ask users to choose which calculation he/she wants. This method calls a method that can add, subtract, or multiply based on the user's option. CalAdd() : add two numbers CalSub() : subtract two numbers CalProduct() : multiply two numbers toString() : toString method that display result of operation. The program should be designed to test the class developed. Your program might look like the following: public class CalculateNumTesting{ public static void main(String[] args){ CalculateNum calculation = new CalculateNum(); calculation.getAsk(); System.out.println(calculation); } }arrow_forwardIn this exercise, you have to implement a calculator which can perform addition, subtraction, multiplication, and division.

- At most, a class can contain ____________ method(S). 0 1 2 any number ofarrow_forwardExercise 2: The intersection method computes the intersection of two rectangles- that is, the rectangle that would be formed by two overlapping rectangles if they were drawn, as shown at right. You call this method as follows: Rectangle r3 = r1.intersection (r2); Write a program IntersectionPrinter that constructs two rectangle objects, prints them as described in Exercise 1, and then prints the rectangle Intersection object that describes the intersection. Then the program should print the result of the intersection method when the rectangles do not overlap. Add a comment to your program that explains how you can tell whether the resulting rectangle is empty. The random class implements a random number generator, which produces sequences of numbers that appear to be random. To generate random integers, you construct an object of the Random class, and then apply the nextInt (50) gives you a random number between 0 and 49. Use the Random class to construct the two rectangle objects.arrow_forwardInstructions This assignment must follow directions exactly.

- 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.arrow_forwardSuppose you have a class named Candy imported and you instantiate an object named reeses. Also, suppose that the Candy class has a method named getFlavor, which requires no arguments.

- Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…arrow_forwardClass 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…arrow_forwardDefine a class named CandyDistributor. A CandyDistributor object represents a hungry child who is going to divide a set of candies between herself and her hungry sibling. This will be done fairly by alternating who gets a candy. Each CandyDistributor object should have the following method: public void nextCandy() Each time nextCandy is called, the method prints a message about who gets a candy, and how many candies that person has. Each call to nextCandy produces a single line of output. The code below constructs a CandyDistributor object and calls its nextCandy 8 times. The output appears at right. public class TestCandy { public static void main(String[] args) { CandyDistributor nice = new CandyDistributor(); nice.nextCandy(); // 1 for you. nice.nextCandy(); // 1 for me. nice.nextCandy(); // 2 for you. nice.nextCandy(); // 2 for me. nice.nextCandy(); // 3 for you. nice.nextCandy();…arrow_forward
