in java eclipse. Please add comments. I have stared the code please in the same code add the following question. Thank you  f. Create a new StringBuilder Object using no-arg constructor. g. Using for loop append the array elements one by one to the StringBuilder (one per loop iteration) h. Record a run-time it took to append all integers to the StringBuilder (record run-time of 2.g.)) i. Repeat the testing with 500 and 5,000 elements by again creating new integer arrays with 500 and 5000 sizes respectively. j. Record and display the run-time it took to append all integers to the String and StringBuilder respectively. k. Submit the screenshot of results and a small summary in the form of a table below : Time / size 50 500 5,000  String        StringBuilder        The image is the code started.

Remove and print green in the list by using the pop() method with the list given below: colors = ["navy", "white", "red", "black", "green", "blue", "red"] Just make sure to precisely match the output format below.Write your code in the ANSWER area provided below (must include comments if using code is not covered in the course). Example Outputgreen

You will implement some methods in the UndirectedGraph class. The UndirectedGraph class contains two nested classes, Vertex and Node, you should NOT change these classes. The graph will store a list of all the vertices in the graph. Each vertex has a pointer to its adjacent vertices. To get started, import the starter file, Undirected.java into the graphs package you create in a new Java Project. Please do not change any of the method signatures in the class, but you can add any helper methods you deem necessary. Implement the methods described below. You are free to test your code however you prefer. Vertex Class (DO NOT EDIT)The vertex class holds information about the vertices in the graph. It has an int val, a Vertex next that refers to the next vertex in the list of vertices (not necessarily an adjacent vertex), and a Node edge that starts the list of adjacent vertices. Node Class (DO NOT EDIT)This is a simple class to represent an adjacency list of a vertex in the graph.…

Please Code in JAVA. Type the code out neatly. Add comments . (No need for long comments). Dont add any unnecesary code or comments. Do what the attached file says. And call it a day. Thanks !

Answer the given question with a proper explanation and step-by-step solution. Write a method that takes in an array of Point2D objects, and then analyzes the dataset to find points that are close together. Be sure to review the Point2D API. In your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. For example, "The distance between (3,5) and (8,9) is 6.40312." The complete API for the Point2D ADT may be viewed at http://www.ime.usp.br/~pf/sedgewick-wayne/algs4/documentation/Point2D.htmlLinks to an external site.. Do not compare a point to itself! Try to write your program directly from the API - do not review the ADT's source code. (Don't worry too much about your answer compiling - focus on using an API from its documentation.) Your answer should include only the method you wrote, do not write a complete program.

i got an error in line where its m=linespace (18,8,6)

how would you do this in java the container class described in question is the other image file

wordBag is type BagInterface<String>. What is printed? wordBag.add("apple");wordBag.add("banana");wordBag.clear();System.out.println(wordBag.remove());
