Class Utilities { Method Details addDelimiter: public static java.lang.String addDelimiter(java.lang.String str, char delimeter) Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…

Edit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2. Are Iterable i.e., support for loops and star arguments for unpacking into function calls3. Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated.

Java RMI modify “MyClient.java”, “Method.java” and “MethodRemote.java” After your modification, re-compile, and run server and client programs, the client asks the user to enter a string. • If a string “time” is entered, the client will get current date and time from server by remotely invocating the method “action()” in server machine. • If another string other than “time” is entered, then the client will get the capitalized version of the string the user just entered by remotely invocating the method “action()” in server machine. • Your client program should keep asking the user’s input for a string unless an empty string is entered (i.e., just press ENTER key without anything else). When an empty string is entered, this client will quit. while a client is being connected to the server, the server should be able to receive new clients’ connections for current date/time or capitalized strings. In other words, the server should concurrently handle multiple clients’ connections and…
Please help me with this , I am stuck ! thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the all of the file: ArrayBag.cpp: #include <string>#include "ArrayBag.h" template <class T>ArrayBag<T>::ArrayBag() :…
Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…
