Step by step
Solved in 3 steps with 1 images
- 1. Given a Vertex object x, give Java code to enumerate its outgoing edges. ("Enumerate" means "to list"; your code does not need to do anything with the edges, but should be setup code that would make it easy to do something with each edge if we wanted to add that in.) 2. Given a VertexAndDist object x and a new distance d, give Java code to create an updated object with the same vertex as x but with distance d. 3. For simplicity of implementation, we use HashMaps to map vertices to handles/parents and edges to weights. How could you modify the Vertex and/or Edge classes, as well as the maps themselves, to implement the maps using ordinary arrays, with no hashing? Be sure to address both the vertex and edge maps in your answer. (Hint: consider the Vertex's "id" field for inspiration.)Modify the GeometricObject classto implement the Comparable interface and define a static max method in theGeometricObject class for finding the larger of two GeometricObject objects.Draw the UML diagram and implement the new GeometricObject class. Writea test program that uses the max method to find the larger of two circles, the largerof two rectangles.Java - Encapsulation Create a class Point with attributes x and y which are both integers. Create getters and setters for these attributes and implement the following methods: 1. calculateDistance() - calculates the distance from the origin to the point. Returns a double, formula is sqrt(x^2 + y^2) 2. printCoordinates() - prints "(x,y)" Ask for user inputs for x and y. Use the methods printCoordinates() and calculateDistance() respectively. Inputs 1. X 2. Y Sample Output Enter x: 20 Enter y: 15 (20,15) 25.00
- Can you implement an interface in your class? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# You are given an interface Addition which contains a method signature int add(int num1, int num2). You need to write a class called Calculator which implements the Addition interface. The add(int, int) method takes two integers and returns their sum. Input# Calls the add(int, int) method by passing num1 and num2. Output# Returns the addition of num1 and num2.I already saw a solution to this problem here, but it is not correct The edge-detection function (detectEdges) described in Chapter 7 and shown below returns a black and white image. Think of a similar way to transform color values so that the new image is still in its original colors but the outlines within it are merely sharpened. def detectEdges(image, amount): """Builds and returns a new image in which the edges of the argument image are highlighted and the colors are reduced to black and white.""" def average(triple): (r, g, b) = triple return (r + g + b) // 3 blackPixel = (0, 0, 0) whitePixel = (255, 255, 255) new = image.clone() for y in range(image.getHeight() - 1): for x in range(1, image.getWidth()): oldPixel = image.getPixel(x, y) leftPixel = image.getPixel(x - 1, y) bottomPixel = image.getPixel(x, y + 1) oldLum = average(oldPixel) leftLum = average(leftPixel)…Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.
- I have modified the code above. The input to test the method floydWarshal(graph,v) will come from the user (from the console through the scanner). v can not be a final variable because the user will determine the value of v. The double array graph will also be determined and input by the user (from the console through the scanner). I'm having issues getting the input from the user and putting it into the double array. I'm also having issues printing the result of the method, which should be the shortest path graph. Please help ------------------------------------------------------------------------------------ HERE IS THE CODE THAT I HAVE SO FAR import java.io.*;import java.util.*;import java.lang.*; public class Solution { final static int INF = 99999; public static void shortWarshall(int graph[][],int v) { int dist[][] = new int[v][v]; int i, j, k; /* Initialize the solution matrix same as input graph matrix.

For each student, use a template literal to print out their name, age, and major in a formatted string. (e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student. Test the code by running it and verifying that it prints out the details of each student in a formatted string.============================================================================== const students = [ { name: "John", age: 18, major: "Computer Science" }, { name: "Newton", age: 19, major: "Mathematics" }, { name: "Barry", age: 20, major: "Physics" }, ]; // Iterate through the array of objects students using for/of // Print a message to the console that includes the student's name, age, and major // Example: John is 18 years old and…Please complete the task by yourself only in JAVA with explanation. Don't copy. Thank you. Using quicksort to sort an array of car objects by various criteria. Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } b) Implement a comparator called CompareCarsByDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg.
- Please help solve this with java i posted it before and got rejected :( Modify the Show class such that it implements the Comparable interface of java.lang. Remember to add the concrete type Show between <> when you implement Comparable. Note the syntax error that occurs and understand why it occurs. 2. Implement (override) the compareTo method in the Show class such that it compares the showsaccording to their rates: returns 1 if the first show’s rate is greater than the second, -1if the first show’s rate is less than the second, and 0 if they are equal. (First show is “this”, second show is o) 3. Define an interface named Ratable, that has the method updateRate as shown in the UML diagram, in a file named Ratable.java. 4. Modify the Show class such that it implements the Ratable interface. Note the syntax error that occurs in the updateRate method and understand why it occurs. 5. Modify the updateRate method in the Show class such that it returns a double value that represents…Are there obvious improvements that could be made here with respect the software design for Squares and Circles? What programming constructs were you familiar with, and which did you need to look up? Assume we used a separate array for Squares and for Circles rather than one unifying Object array. How would this complicate the task of adding a new Shape (say, a Triangle) to our ObjectList class?Design and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML Class diagram. Create a separate driver class that prompts the user for the sample size, then instantiates a RandomArray object of that size and outputs its contents and the minimum, maximum, and average values.
