Language of All those words which ends with bb and have odd length.9. Language of All those words which do not end with ba.Design and code a class in C++ that represents a single month of the year. It should have a single integer-typed data member to represent the month. Make sure to provide proper construction, access, and mutation for this member as well as input and output methods. In addition, methods for comparing two months chronologically for ordering would be useful as would a method to advance to the next month (note that January follows December and begins the cycle anew) or previous month. In fact, thinking about it, it might be good to be able to advance to a month an arbitrary number of whole months in the future or past: January '+' 5 = June; March '-' 5 = October. Place your Month class in a library. Write a test application (driver) for your class. Oh, and the programmers who commissioned this class wanted to make sure it could handle not only integer-valued representation of a Month but also either whole-word names or three-letter abbreviations for the Months. That means that they should…Create a calculator for the complex number by creating a class of complex number with overloading all operators in it.(Operators: ++,-,+/,>>, <<).
- Design a class named LinearEquation for a 2x2 system of linear equations: ax + by = ecx + dy = f x = (ed - bf)/(ad - bc ) y = (af - ec)/(ad-bc) The class contains:■ The private data fields a, b, c, d, e, and f with get methods.■ A constructor with the arguments for a, b, c, d, e, and f.■ Six get methods for a, b, c, d, e, and f.■ A method named isSolvable() that returns true if is not 0.■ The methods getX() and getY() that return the solution for the equation.Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If is 0, report that “The equation has no solution.”Design a class named LinearEquation for a 2-by-2 system of linear equations:ax + by = e x=(ed-bf)/(ad-bc)cx + dy = f y=(af-ec)/(ad-bc)The class contains:• Private double data fields a, b, c, d, e, and f.• A constructor with the arguments for a, b, c, d, e, and f.• Six getter methods for a, b, c, d, e, and f.• Methods getX() and getY() that return the solution for the equation.• A method named isSolvable() that returns true if ad - bc is not 0. The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”.Write a test Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.Create a subroutine that breaks down a noun-verb-object simple sentence into its component components. For example, the phrase "Mary walked the dog" is deconstructed as follows:Noun: MaryVerb: walkedObject: the dog The dog is the object.This function should be compatible with both StringBuilder and String objects.
- Write a subroutine that takes a simple sentence in noun-verb-object formand parses the sentence into its different parts. For example, the sentence“Mary walked the dog” is parsed into this:Noun: MaryVerb: walkedObject: the dogThis function should work with both String objects and StringBuilderobjects.Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing. The String class has a lot of functions and continues to grow. See https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create a java program that when give a sentence will replace the first occurrence of NUST with Namibia University of Science and Technology. Sample run 1: Enter a sentence: Welcome to my NUST. Output: Welcome to my Namibia University of Science and Technology. Sample run 2: Enter a sentence: The nust is a great institution of high learning. Output: The Namibia University of Science and Technology is a great institution of high learning.Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing.

Use classes and apply the encapsulation rules also. In an online shopping cart, the system must maintain a list of items and must calculate the total bill by adding the amount of all the items in the cart. Do Following: First create a class Item having id, name, price, and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in the cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in the list Display all items. Traverse the link list so that each item's bill gets calculated (by multiplying quantity with price) and also calculate and display the Total bill in the end. Delete an item if the user wants to remove an item from the cart.Write a subroutine that takes a simple sentence in noun-verb-object form and parses the sentence into its different parts.
