Chapter 9.6, Problem 9.31CP
Program Plan Intro
Tokenizing Strings:
- The tokenizing of a string denotes a process of dividing a string into its components termed as tokens.
- The “split” method of “String” class could be used for tokenizing strings.
- The character that would separate tokens is termed as “delimiter”.
- The argument that is passed to “split” method denotes a regular expression.
- A regular expression is used to search for patterns in strings, files and other texts.
- To prevent leading or trailing whitespace characters in tokens, the string is been trimmed.
- The “trim” method of “String” class is been used for trimming purposes.
Wrapper class:
- The wrapper class is been provided by Java API for numeric data types.
- These classes contain methods that perform useful operations.
- It involves primitive numeric values.
- The static “toString” method converts to a string from a number.
- The method that accepts number as its argument.
- It returns a number’s string representation.
- The “toBinaryString”, “toHexString”, and “toOctalString” accepts integer as argument.
- It returns string representation of number converted into binary, hexadecimal and octal.
- The “MAX_VALUE” and “MIN_VALUE” stores maximum and minimum value for a specific data type.
- The “Autoboxing” denotes a java process for automatically boxing up a value inside an object.
- The “Unboxing” denotes a reverse process of boxing; it converts a wrapper class object into a primitive type.

- C++ Stars This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its destructor called,…arrow_forwardclass Currency { protected: int whole; int fraction; virtual std::string get_name() = 0; public: Currency() { whole = 0; fraction = 0; } Currency(double value) { if (value < 0) throw "Invalid value"; whole = int(value); fraction = std::round(100 * (value - whole)); } Currency(const Currency& curr) { whole = curr.whole; fraction = curr.fraction; } /* This algorithm gets the whole part or fractional part of the currency Pre: whole, fraction - integer numbers Post: Return: whole or fraction */ int get_whole() { return whole; } int get_fraction() { return fraction; } /* This algorithm adds an object to the same currency Pre: object (same currency) Post: Return: */ void set_whole(int w) { if (w >= 0) whole = w; } void set_fraction(int f) { if (f >= 0 && f <…arrow_forwardCode in Java keep the code as simple as possible do not use arrays nor parseItnt StringBuilder etc keep it very simple.Proper setters, getters, constructors, and toString methods for all of the classes Class Text This is a text editing class. In its constructor it receives a string. The string will be stored in a field called initialValue using proper setter methods and proper documentation for Each of the methods . The class also contains another String field called: ”mixedResult” which is only defined globally and will be initialized using a method in the future in the main class namely the mix method. The public String toToken() method is a method that will use the initialValue field and it for the letter ’p’ or the letter ’A’. If it finds the letter, every element on the left side of the found letter will be stored in another string and returned. For example: If the initialValue was: ”This is a possible resource allocation”. The returning String will be: ”possible resource…arrow_forward
