You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array.

Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output. • Given the annual interest rate, the interest amount earned each month is computedusing the formula: Interest earned = investment amount * annual interest rate /1200 (=months * 100) • Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following: o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop). o Returns the total interest amount earned after the number of months specified bythe user. The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user.

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
Exercise 5 - Number to Word Make a new class in the Lab2 project called Num2wordthat prompts the user enter a number between 0 and 9 and then displays the corresponding word (i.e. "zero"for 0, "one"for 1, etc.). Use a switchstatement to do this. Include a default case that lets the user know they entered a wrong number. The switch statement has the following syntax: switch (variable) { case value1: // Code that should execute when variable==value1 break; // this prevents it from automatically going to the next case case value2: // Code that should execute when variable==value2 break; // this prevents it from automatically going to the next case default: // Code that should execute when variable has a value that didn't match the above }

Program63.javaWrite a program that estimates the cost of carpet for one or more rooms with rectangular floors. Begin by prompting for the price of carpet per square yard and the number of rooms needing this carpet. Use a loop to prompt for the floor dimensions of each room in feet. In this loop, call a value-returning method with the dimensions and carpet price as arguments. The method should return the carpet cost for each room to main, where it will be printed and accumulated. After all rooms have been processed, the program should display the total cost of the job.Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
Please try to explain how to do it. Please in java file. Loops is the topic.
1. Instructions: The program you will analyze is shown below. The program listing contains a class definition followed by a main program. Your task is to find and write the missing code lines to make the program work correctly. Use the output statements from the print() statements to reveal this mystery :-) Please write the missing code lines clearly in the empty boxes. ###### start of Rectangle class class Rectangle: def init (self, length, width): self.length length self.width = width def GetLength (self): return self.length def GetWidth(self): return self.width def GetArea (self): return self.length * self.width def SetScale(self, scale): self.length self.length * scale self.width self.width * scale #### start of main program rec Rectangle (3,5) %3D print ('Rectangle Area: ', rectangleArea) for ES in range (2,5) : width = rec.GetWidth()
