- Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2+5= Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+,-, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…problem statement: Write a java classStringCheckto do the below given checks on accepted string or strings. Each function should be coded in separate methods of the class. Give appropriate instance variables to implement the method. The user should be able to enter the string through the main function in Main class. Use a constructor to initialize the String entered by the user. Use the Main class to test all the methods in StringCheckclass. The programs should have the below given checklist: 1)Define classStringCheck with required instance variables 2)The StringCheck class should have six methods to do the below functions: *Check if the user entered string is a simple sentence? (Starts with capital letter, Ends with period, space between words). *Check if the user entered string is a question? (Check if the string starts with ac apital letter ends with a question mark, space between words) *Check if the user entered string have numbers in it? *Check if string is a valid email *Check…Which statement is false? Select one: a. The compiler always creates a default constructor for a class. O b.If a class has constructors, but none of the public constructors are no- argument constructors, and a program attempts to call a no-argument constructor to initialize an object of he class, a compilation error occurs. O c.A constructor can be called with no arguments only if the class does not have any constructors or if the class has a public no-argument constructor. O d. Java allows other methods of the class besides its constructors to have the same name as the class and to specify return types.

The class also contains the following static data members. v number (Type in The class also contains the following methods. V No Argument_constructor to give initial values for all data Full constructor that accepts values of all data members as àrguments from the user. V setName ()method to reset the Vname of the Video. V getName ( method to return the Vname of the Video. Homework2 CS2301 2 /I| asid V setPrice () method to reset the myPrice of the Video. V getPrice () method to return the myPrice of the Video. v display () method that prints out the class data. V main () method to test the functionality of the class, asking the user to enter any necessary data. Note: the static data member (number) is set to 0 and it is increment by 1 when an object is instantiated.

(b) Write the constructor foe the class that takes two parameters to set the location and the number of seats.!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı

Write a class called profileID, which has data members firstName,lastName, age, birthday and ageCompany (the age when you entered in the company). Remember to use set and get methods to access the data members this time. Also, write another class called bonusAward that has a method getBonus()with arguments yos and etype which are both integer data types. This method calculates the bonus received by an employee using this formula: yos*1000 + etype*1000. Write two derived classes, ASE and SE, using multiple inheritance usingprofileID and bonusAward as parent classes. Both classes must have amethod named getyos()that returns the yos of an employee using the formula age–ageCompany; and a method named getetype() which returns a constant based on the employee type. For ASE, the constant is 10 while for SE that constant is 20. Last, write a main program where you instantiate ASE as employee1 and SE as employee2.
