Question
If we generated a string like ‘Thanks’ from objects, is it identical to the string value as ‘Thanks’?
```python
joined_string = ''.join(['T', 'h', 'a', 'n', 'k', 's'])
thanks = 'Thanks'
joined_string is thanks # What is the result of this line? And Why?

- Write the code in java and please dont plagarise and dont copy from other sources or use anything. Do what in the question says. Thank you.arrow_forwardAdd a new method to ArrayTools with filter. Make this method accept a String array. Change all the Strings that are longer than 5 characters to uppercase. Write in Java and use test cases 1 & 2 as a result.arrow_forwardWrite a string class. To avoid conflicts with other similarly named classes, we will call our version MyString. This object is designed to make working with sequences of characters a little more convenient and less error-prone than handling raw c-strings, (although it will be implemented as a c-string behind the scenes). The MyString class will handle constructing strings, reading/printing, and accessing characters. In addition, the MyString object will have the ability to make a full deep-copy of itself when copied. Your class must have only one data member, a c-string implemented as a dynamic array. In particular, you must not use a data member to keep track of the size or length of the MyString. #include "mystring.h" #include <cctype> #include <iostream> #include <string> using namespace std; using namespace cs_mystring; void BasicTest(); void RelationTest(); void CopyTest(); MyString AppendTest(const MyString& ref, MyString val); string boolString(bool…arrow_forward
- Write a java class method named findFourLetterWord that searches an array of words (String objects) for a wordthat’s four characters long. The array will be the method’s only parameters. findFourLetterWord will return thefirst four-letter word that it finds. If none of the words have the proper length, the method will return null.arrow_forwardThe following is the specification for the constructor of a EmailFolder class: /*** Creates a new EmailFolder with the given label** @precondition label != null AND !label.isEmpty()* @postcondition getLabel()==label*/public EmailFolder(String label) Assume the variable folders is an array list of EmailFolder objects. Write code to add a new EmailFolder to the list.arrow_forwardImplement a new concat method in the String class you worked on for HW2. The method should return a new String object that represents the text you would end up with if the argument String were "added onto the end of" this String. For example, in the code below, the String object answer should represent the text "bookstore" and true should be printed the screen. char[] bookA = {'b', 'o', 'o', 'k'}; char[] storeA = {'s', 't', 'o', 'r', 'e'}; char[] bookstoreA = {'b', 'o', 'o', 'k', 's', 't', 'o', 'r', 'e'}; String book = new String(bookA); String store = new String(storeA); String bookstore = new String(bookstoreA); String answer = book.concat(store); System.out.println(answer.equals(bookstore)); In the text area below, type in your definition of the concat method. (In other words, type in the code that should replace the //TODO comment.) Your code cannot call any methods. public class String { private char[] data; public String(char[] value) { data = new…arrow_forward
- in python. For this project, you will import the json module. Write a class named NobelData that reads a JSON file containing data on Nobel Prizes and allows the user to search that data. Your code does not need to access the internet. Your class should have: an init method that reads the file and stores it in whatever data member(s) you prefer. Any data members of the NobelData class must be private. a method named search_nobel that takes as parameters a year and a category, and returns a sorted list (in normal English dictionary order) of the surnames for the winner(s) in that category for that year (up to three people can share the prize). The year will be a string (e.g. "1975"), not a number. The categories are: "chemistry", "economics", "literature", "peace", "physics", and "medicine". For example, your class could be used like this: nd = NobelData() nd.search_nobel("2001", "economics")arrow_forwardwhat should I add to make it reject a number? and ask the user to not enter a number by displaying "Syllable must only contain letters or a wildcard" def add_gibberish(word, gib1, gib2):vowels = "AaEeIiOoUu"flag = Truelast = Falsei = 0while (i < len(word)): #traverse whole wordif word[i] in vowels: # if character in a word is vowelif last == False: # if last charcater was not vowelif flag == True: #check if first occurence of vowelword = word[0:i] + gib1 + word[i:len(word)] #add gibberish to the wordi = i + len(gib1) + 1flag = Falselast = Trueelse:word = word[0:i] + gib2 + word[i:len(word)] # if other than first occurence of voweli = i + len(gib2) + 1last = Trueelse:i = i + 1else: # if character is not vowellast = False # set last character was not voweli = i + 1; return word def start():gib1 = input("Enter first gibberish syllable: ")gib2 = input("Enter second gibberish syllable: ")word = input("Enter a word to translate: ")new_word = add_gibberish(word, gib1,…arrow_forwardWrite 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".arrow_forward
