Chapter 10, Problem 10.22PE
(Implement the String class) The String class is provided in the Java library. Provide your own implementation for the following methods (name the new class MyString1):
public MyString1(char[] chars):
public char charAt(int index);
public int length();
public MyString1 substring(int begin, int end);
public MyString1 toLowerCase();
public boolean equals(MyString1 s);
public static MyString1 valueOf(int i);

public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString();
Here's the tester it must pass:

str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result
back to an immutable string, that is,
str = new StringBuilder(str).reverse().tostring();
A bit convoluted, but does what is needed without fuss or muss. Maybe one day the Java strings will
come with the reverse method built in, just like the string data types of all sensible…

- Public class Utilities { getDigits Method: public static java.lang.String getDigits(java.lang.String str) Returns a string with the digits (if any) present in the str parameter. You can assume str will never be null. You can use Character.isDigit() to determine whether a character is a digit. 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. 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 - Returns: String with digits or empty stringarrow_forward#include #include using namespace std; class String { private: public: int size; // the actual size of the string (number of characters) char* str; String() { str = nullptr; size = 0; } String(const char* mystr); //create a String object and copy the null- terminated string mystr to str. int length(); // returns the size of the string int find(String findstr); // return the index of findstr in str; return -1 if not found. index String substr(int index, int size); // returns a String object with starting index and size-size. void clear();// delete the array of chars and reset the size; void insert(const char newstr, int index); // inserts the null-terminated newStr into str starting at index. void insert(String S, int index); // inserts 5.str into str starting at index, and adjust the size. void input (istream& is); // reads a string from a keyboard (Assume the strign size is less than or equal to 80) void output (ostream& os); // prints the string str; }; int main() { UAE 0 String…arrow_forwardWrite a method that returns the index of the smallest element in an array of doubles.

- (YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.arrow_forwardDo not use static variables to implement recursive methods.

With s1=”aabbaa” and s2=”AA”, countSubStrings returns 0. Show the output on the following strings: s1 = “Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems Java platform.
