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.

Using Java. Implement a deque, except base your implementation on an array. The constructor for the class should accept an integer parameter for the capacity of the deque and create an array of that size. Use a graphical user interface based on an array of text fields similar to what is shown in the image attached. Test your deque class by constructing a deque with capacity 10.   Below also is an unfinished code for the challenge. #################################Array Based Deque################################# public class ArrayBaseDeque{private String [ ] q; // Holds queue elementsprivate int front; // Next item to be removedprivate int rear; // Next slot to fillprivate int size; // Number of items in queue private int count = 0;/**Constructor.@param capacity The capacity of the queue.*/ArrayBaseDeque(int capacity){q = new String[capacity];front = 0; rear = 0;size = 0;}/**The capacity method returns the length of the array used to implement the queue.@return The capacity of the…

Write two methods, myCode() and helloWorld(String[] args).   The myCode() method must: 1. Create a String array with these elements: "Hello" "World" 2. Call helloWorld(String[] args) method, using the array you created as the parameter.   The helloWorld(String[] args) method must: 1. Replace the word "World" with the word "CityTech".

Description is " A MathVector object will be passed to your method.  Return its contents as a String.   If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String.  This makes it useful for displaying to the user.     You might have noticed that there's an @override term there.  That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default.  Here, the override tells Java "I know, I know.  You already have a toString() that you'd assign here.  But it's not good enough.  Here's a better one for this particular kind of object."  It's a little bit like saying "Most humans have two legs.  So, by default, I'll give everyone two legs.  But sometimes we override that and give no legs, or just one leg to a person.  And sometimes we give them four so that they can be a centaur!"   To use this in a println() method, just name your object.  The toString()…
