- Write an abstract data type for rational numbers (a numerator and a denominator). Include a constructor and methods for getting the numerator, getting the denominator, addition, subtraction, multiplication, division, equality testing, and display. Use Java or C++.Write the differences between Class and Interface with example in javaIn Java, implement Abstraction in the grading system. Include three different implementation methods in solving the grade. Kindly follow the example of coding below (abstract class should be included): Example: Prelim 30 Midterm 30 Endterm 40 --------------------- Formula: (Prelim+ Midterm + Endterm)/3 ------------------------------

THANK YOU! For this assignment, we will simulate boarding procedures for Airworthy Airlines. The Airline's current procedure is as follows: pre-board in the following order: families with young children or people who need help (e.g., wheelchair) first class and/or business class passengers elite passengers (frequent fliers) and those passengers seated in exit rows conduct general boarding in reverse, from the back of the plane to the front in the following order: rows 23-26 rows 17-22 rows 11-16 rows 5-10 Airworthy is considering revising their boarding procedure such that general boarding is done randomly, meaning the first passenger in line for general boarding is the first passenger to board (i.e., general boarding passengers all have the same priority). Airworthy suspects this random general boarding method will improve the flow of passengers, getting them on board and seated more quickly. It is also less labor-intensive…Mixed Fraction Arithmetic Java Project: Problem Description: Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers (similar with the first activity) but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination. Points to consider: MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole…
- Develop with Java programming language a calculator (console application) that takes a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input, and have it print the result of the mathematical operation. The mathematical operations should be wrapped inside of functions. Note: Do please use the provided source code template to implement your solution. The purpose of this problem is not only to assess the students' ability to build a valid implementation but also to assess the ability to read the Java code. Input: On single line a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input. Output: On new line result of the mathematical operation. In the case of "Division by zero" you must printout the text message "Error". The code must have the structure as shown in the picture and should work for negative numbers as wellUse java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.
