- IN JAVA intends to auto generate test cases for a function foo that has k integers as input arguments, i.e., foo(int n1, int n2, …, int nk). Each argument belongs to a different equivalence class, which are stored in a downloadable Eq.txt file. The content is shown below and may be modified to handle more inputs and equivalence classes. 1, 15; 16, 30 1, 10; 11, 20; 21, 30 1, 5; 6, 10; 11, 15 1, 3; 4, 6; 7, 9; 10, 12 1, 12; 13, 24 For this file, the nth row describes the nth input. Take the second row for example. There are five input arguments. The data 1, 10; 11, 20; 21, 30 indicates that argument n2 has three equivalence classes separated by the semi-colons. Develop an internal method “private int check(int val)” that returns the equivalence class the val is in. The result of check(val = 3) for n2 will be 1 and check(val = 25) for n2 will be 3. Regarding the function foo, it computes the sum of the returned values by the check function for all input arguments.

- Given two points in the plane (?,?) and (?,?), the slope of the line through them is the number ? given by?=?−? ?−?i.e. the difference in the y-coordinates divided by the difference in the x-coordinates, or rise/run. Recall the Point class defined in the series of examples found here. Below is a stripped down version of this class, with only the initializer (given), and two new class functions called slope(?,?) and colinear(?, ?, ?). The first returns the slope of the line through the points ? and ?. The second returns True if and only if the three points ?, ? and ? lie on a line.In Frac.h, extend the methods addition( const Fraction & ),subtraction(const Fraction&), multiply(const Fraction &); divide(const Fraction &); void printFraction(); by overloading operators +, -, *, /, << respectively. The concept of extend can be achieved by keeping the existing functions (e.g. addition(const Fraction &), and etc.) and design the extended functions through calling the existing functions. Add overloading operators > and < so that they can compare two FractionsWrite your own implementation file which is named Frac2.cpp to replace Frac.cpp and implement the Fraction class and the necessary overloading operators. Download the driver Frac2Driver.cpp download to test your codes. If your codes in files Frac2.h and Frac2.cpp are correct, the standard output after the execution of your program should like the following: 7/3 + 1/3 = 8/37/3 - 1/3 = 27/3 * 1/3 = 7/97/3 / 1/3 = 77/3 is:> 1/3 according to the overloaded > operator>= 1/3…Write the following program in python; There is a class with m number of students and they have n number of lessons. a)For each lesson the program has to find arithmetic,geometric,harmonic average of class b)point avarage of each student c)student numbers of highest and lowest avarage point of the class and those points too also d)for each lesson result of highest point minus lowest point e)for each lesson result of highest avarage minus lowest avarage NOTE: M and N numbers will be choosed by keyboard after.
- suppose there is a class Roster. Roster has one variable, roster, which is a list of tuples containing the names of students and their numerical grades- for example, [('Richard',90), ('Belle',67), ('Christine',85), ('Francine',97)]. Roster has a function findValedictorian that returns the name of the student with the highest grade. Find the valedictorian of the Roster object englishClass and store it in the variable valedictorian. using pythonWrite a program in C that simulates a checkout line at a supermarket. The line is a queue object. Customers (i.e.,customer objects) arrive in random integer intervals of 1–4 minutes. Also, each customer is served in randominteger intervals of 1–4 minutes. Obviously, the rates need to be balanced. If the average arrival rate is largerthan the average service rate, the queue will grow infinitely. Even with “balanced” rates, randomness can stillcause long lines. Run the supermarket simulation for a 12-hours a day (720 minutes) using the followingalgorithm:1. Choose a random integer from 1 to 4 to determine the minute at which the first customer arrives.2. At the first customer’s arrival time: Determine customer’s service time (random integer from 1 to 4);Begin servicing the customer. Schedule arrival time of next customer (random integer 1 to 4 added to the current time).3. For each minute of the day: If the next customer arrives, Say so, Enqueue the customer.Schedule the arrival time of…Suppose we're in a class called Vitamin and we have a private member variable named dosage of type double.
