The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters. public static String[] split(String s, String regex) For example, split("ab#12#453", "#") returns ab, #, 12, #, and 453 in an array of String and split("a?b?gf#e", "[?#]") returns a, ?, b, ?, gf, #, and e in an array of String.

Write a method to replace all spaces in a string with '%20'. You may assume that the stringhas sufficient space at the end to hold the additional characters, and that you are given the "true"length of the string. (Note: If implementing in Java, please use a character array so that you canperform this operation in place.)EXAMPLEInput: "Mr John Smith ", 13Output: "Mr%20John%20Smith"

Implement the copy assignment operator= for the StringVar class using the options given on the right side window. Place the code into the left side using the arrows. It is possible to get the test case correct but not complete NOTE: Be careful! There are decoys! The this pointer is used extensively.. Assume that StringVar.h has the following declaration: #include <iostream> class StringVar {public:StringVar() : max_length(20) { // Default constructor size is 20value = new char[max_length+1];value[0] = '\0';}StringVar(int size); // Takes an int for sizeStringVar(const char cstr[]); // Takes a c-string and copies itStringVar(const StringVar& strObj); // Copy Constructor~StringVar(); // Destructorint size() const { return max_length; } // Access capacityconst char* c_str() const { return value; } // Access valueint length() const { return strlen(value); } // Access lengthStringVar& operator= (const StringVar& rightObj);std::istream& operator>>…

Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. Use the following files: Question.java /**   A question with a text and an answer.*/public class Question{   private String text;   private String answer;    /**      Constructs a question with empty text and empty answer.   */   public Question()    {      text = "";      answer = "";   }    /**      Sets the answer for this question.      @param correctResponse the answer   */   public void setAnswer(String correctResponse)   {      answer = correctResponse;   }    /**      Checks a given response for correctness.      @param response the response to check      @return true if the response was correct, false otherwise   */   public boolean checkAnswer(String response)   {      return response.equals(answer);   }    /**      Add a line of text to…
