Construct an OOP using classes and objects to find the distance travelled by a Vehicle in t" seconds is given by (аxt?) Distance d = u xt = 2 Here, "u" is the initial velocity (meters per second) and "a" is the acceleration (meters per second). Write an OOP to evaluate the distance travelled at regular intervals of time for the given the values of "u" and "a". The program should provide the flexibility to the user to select their own time intervals and repeat the calculations for different values of "u and "a" and tabulate the result.

- In java language Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length. Remember that the job of the constructor is to initialize the instance variables. It has these methods. public double getWidth() - Gets the width of this Rectangle public double getLength() - Gets the length of this…In java language Write a Rectangle class.

Every solid will have a volume. The method volume will be polymorphic. A solid has faces, vertices and edges. A flat-surface solid also has a variable called side which represents the length of the side. A curved-surface solid also has a radius. A Cube is a FlatSurfaceSolid. A cube has 6 faces, 8 vertices and 12 edges. It will have a side. A Sphere is a CurvedSurfaceSolid. It has 1 face, 0 vertices and 0 edges. It will have a radius. Create an ArrayList of solids (driver file named YourLastNameCISC231Q1.java). The arraylist will have 4 elements – 2 cubes (one with side length 3 and another will side length 4) and 2 spheres (one with radius 3 and another with radius 4). Create a driver class to instantiate an array of solids and display the details of each solid along with the volume of each solid.
- 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):booleanWrite a class Point for 2D Cartesian co-ordinates. The class should have 2 fields: abscissa(x) and ordinately). The class should have a method which takes a Point object as parameter and finds the distance between the two points (calling object & argument). The class should also have a static method that takes 2 point objects and returns their midpoint as a new Point object. (No driver class or no other methods required) The distance (d) between 2 points (x1, y1) and (x2, y2) is given by: d = (x1 – x2)2 + (y1 – y2)² The midpoint (x3, y3) between 2 points (x1, y1) and (x2, y2) is given by: x3 = (x1+x2)/2 y3 = (y1+y2)/2Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently.

- Design and implement the class Day that implements the day of the week in a program. The class Day should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type Day: Set the day. Print the day. Return the day. Return the next day. Return the previous day. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday. Add the appropriate constructors. Write the definitions of the methods to implement the operations for the class Day, as defined in A through G. Write a program to test various operations on the class Day. note: javaDesign and implement the class Day that implements the day of the week in a program.

For example, a degree can haveo John Smith, 2020, Computer Science It should have at least the following methods: o toString method must return all the degree information: year,subject and person’s name in the following format:NAME(John Smith) SUBJECT(Computer Science) YEAR(2020)o hasTheSameDegree method that compares 2 degrees and returntrue if both have the same year and the same subject. Otherwise, itreturns false. Important notes:You can add as many other methods as you need. But this class should not provide the default constructor. Show how this class being used to create Degree objects and how these methods are being called and return proper values. All data members must be declared as “private” No global variable is allowed to be declared and used Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and…
- Use java to write a test program that creates an array of 4 Worker objects. For each object, display theworker’s information and also his/her monthly salary. Both the HourlyWorker and SalariedWorker classes are required to provide anoperation to calculate the worker’s monthly salary. The salaried worker is paid a monthly basic salary + allowance.An hourly worker is paid payRate * hoursWorkedCreate a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…Write the source code of the class Passenger. A passenger can travel with an infant (i.e. his/her child). Code the class Infant as an inner class of the class Passenger. If a passenger is not travelling with an infant, the getInfantMonths method must return –1.
