Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right, up or down. Each of these four moves should occur with equal probability. The resulting behavior is known as a "random walk." (A 2-dimensional random walk example is pictured at right.) Each RandomWal ker object should have the following public methods. You may add whatever fields or methods you feel are necessary to implement these methods:

Define class Shape, 2DShape and 3DShape as per UML class diagram given. 2. Define all mutator methods(set and get) for all classes. 3. Define methods calArea() with formula area - width * length for 2DShapes. 4. Define methods calArea() with formula calvolume, volume = width*length*height for 3DShapes. In the main program, declare and set data in 1 object of 3DShapes. Create an array OR ArrayList of 2DShapes, set and display the info of all objects as shown in the output. 5.
Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.
IN JAVA Cartesian Item Programming Depiction of the test: The Cartesian result of two arrangements of numbers An and B is characterized as the arrangement, all things considered (a,b) where an is an individual from An and b is an individual from B. It is frequently addressed by the image A x B and is alluded to as the Cartesian item since it starts in Descartes' meaning of logical calculation. The Cartesian result of two arrangements of genuine numbers is as requested sets. for example An equivalents [1, 2, 3]. B approaches [4, 5]. C = [(1, 4), (1, 5), (2,4), (2.5), (3,4), (3,5)] is the Cartesian item. Presently, given a facilitate tuple (i,j), where I signifies A[i] and j indicates B[j], and knowing A, B, develop a capacity that profits the file of a part in Cartesian item C as per (i,j) Introduction code: Primary public class /** * Repeat over the information lines individually. */ IOException is tossed by open static void main(String[] args). new…

An object of the class Timer is used to indicate when a certain amount of time (in seconds) has elapsed, after which it provides a “DING”. The required data field is remainingTime which is the number of seconds until the “DING”. When a Timer object is constructed, it is set with the desired number of seconds. When the timer “ticks”, it is one second closer to the “DING”. This is represented with the tick() method. The dingCheck() method indicates whether the timer should be “DINGING”. Provide the code for the constructor method, and the methods getRemainingTime(), tick(), and dingCheck(). public class Timer { // Methods // Data private int remainingTime; }
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. Using Java, create the following classes and primary program that uses the classes that you developed. INS T RUCT IONS Create the following classes. A N I MA L C LA SS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the…
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…
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 =…

Knapsack Problem This exercise is due Tuesday, May 14. It has to be turned in on time in order to get participation credit. I'll come into class and go over the solution right away. Then I will collect your work on the exercise. Be ready to turn it in at that time. Fill out the table for the knapsack problem, where the objects, weights, and values are as given, and the overall weight limit is 10. Next, circle the entries in the table that are used when backtracking to find objects to use in the solution. Then list the object numbers that can be used for an optimal solution. Also list the weights and values of those objects. Verify that the values of your solution objects add up to the optimal number in the last row and column in the table. Verify that the sum of the weights of your solution the objects is not more than the overall weight limit of 10. Weight Capacity -----> obj # wt val | 0 1 2 3 4 5 6 7 8 9 10…
