- Create a class Rectangle. The class has attribute length and width, each of which defaults to 1. It has methods that calculate the perimeter and area of the rectangle. It has set and get methods for both length and width. The set method should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class RectangleIn this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }
- Write an equals method for the Car class given here. Two Cars are equal if their Vehicle Identification Numbers (VIN) are the same. HINT: The String class has an equals method that can be called from the Car class equals method.Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanIn this exercise, you have to implement a calculator which can perform addition, subtraction, multiplication, and division. Problem Statement# Write a Java class called Calculator with ● private fields: ○ num1 and num2 (double type) And methods: ● add(), a method which returns the addition of two numbers ● subtract(), a method which returns the subtraction of num1 from num2 ● multiply(), a method which returns the multiplication of numbers ● divide(), a method which returns the division of num2 by num1 ● Define a parameterized constructor which takes two parameters num1 and num2 and assigns these variables to the respective fields in the class. Input# Pass double point numbers in the parameterized constructor Output# addition, subtraction, division, and multiplication Sample Input# Calculator obj = new Calculator(10, 94); obj.add() obj.subtract() obj.multiply() obj.divide() Sample Output# 104 84 940 9.4 Part of the Solution class Calculator { // write class fields here public…
- In this assignment, you will implement a simple game in a class called SimpleGame. Thisgame has 2 options for the user playing. Based on user input, the user can choose to eitherconvert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits inan integer.It has been realized that hackers have started hacking and changing the account detains of some banks, to stop this practice, you have been tasked to create a class called Abaaneke, your class should contain three variables (deposit, oldBalance, newBalace) all of type float and a variable of type String (name of the account holder) Your class should also have a method that takes three arguments – name of account holder, amount deposited and old balance. The method should add the deposit to the oldBalance and call it new balance. Using the right setters and getters, initialize the private variables and call the method to display the following in main a. Account holders name b. Amount deposited c. Old balance d. And new balanceComplete the Team class implementation. For the instance method get_win_percentage(), the formula is:team_wins / (team_wins + team_losses) Note: Use floating-point division. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Congratulations, Team Ravens has a winning average! If the input is Angels 80 82, the output is: Team Angels has a losing average. coede used: class Team: def __init__(self): self.team_name = 'none' self.team_wins = 0 self.team_losses = 0 # TODO: Define get_win_percentage() if __name__ == "__main__": team = Team() team_name = input() team_wins = int(input()) team_losses = int(input()) team.team_name = team_name team.team_wins = team_wins team.team_losses = team_losses if team.get_win_percentage() >= 0.5: print('Congratulations, Team', team.team_name,'has a winning average!') else:…
- Complete the Team class implementation. For the instance method get_win_percentage(), the formula is: team_wins / (team_wins + team_losses) Note: Use floating-point division. Ex: If the input is: Ravens 13 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Congratulations, Team Ravens has a winning average!Write a class called Investment with fields called principal and interest. The constructor should set the values of those fields. There should be a method called value_after that returns the value of the investment after n years. The formula for this is p(1+i)ⁿ, where p is the principal, and i is the interest rate. Use python as programming language.Q3. Modify the class by adding another method that prompts user for a positive integer. The program shall read the input as int; and print the "reverse" of the input integer. For example, Enter a positive integer: 12345 The reverse is: 54321 Hint: Use the modulo operator.
