1A. Create a Die class with one integer instance variable called sideUp. Give it a constructor and a getSideUp() method that returns the value of sideUp and a void roll() method that changes sideUp to a random value from 1 to 6. [Note: To generate a random integer between 1 and 6, use Math.random() method] Then create a DieDemo class with a main method that creates two Die objects, rolls them, and then prints the sum of the two sides up.

- Override the testOverriding() method in the Triangle class. Make it print “This is theoverridden testOverriding() method”. (add it to triangle class don't make a new code based on testOverriding in SimpleGeometricObject class.) (this was the step before this one) Add a void testOverriding() method to the SimpleGeometricObject class. Make it print“This is the testOverriding() method of the SimpleGeometricObject class”Create a class Car with parameters companyName, color, maxSpeed (Not more than 150) andcategory. Use appropriate data types and access specifiers. Use default constructor to create objectsof cars. Write methods to set and get the values of parameters of car. Write methods to find categoryof car and to display the complete details of car along with category. Create another class TestCarwhich creates array of n number of cars, uses appropriate set methods to set the values of parametersof every car. Display the details of each car. (If max speed is between 120 and 150 then category is“High speed” otherwise “Normal”) (JAVA). Create a testEmployees class. Do the following: Declare an array called arrEmp of 10 Employee type objects in the main method. Write a static method called fillArray() that receives the arrEmp array. Use a while loop to enter the information (type of contract) of a number of new employees. Quit input by entering the character X instead of the type of contract. For each employee create an object and save the object in the array. Return the array to the main method. Call the static fillArray() method from the main method. Write a static method called displayArray() to receive the array and display a numbered list of the information of the employees using a for-loop and the toString() method. Call the static displayArray() method from the main method. Write a static method called updateEmpCommission() to receive the array and update the commission of some of the employees as follows: Use a loop to update a number of employees' commission. Use a sentinel value -1 to…
- in computer programming: java Create a rectangle class that can compute the area and the sum of its sides. Create a specialized method that will allow the class to compare other rectangle objects. The comparison should identify the larger rectangle according to the object’s area. You should be able to implement the class where the user provides rectangle dimensions. The program should be able to display which of the rectangle inputs is larger using the Rectangle class method that you defined. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Results: R1 Area: 1 R1 Sum: 2 R2 Area: 4 R2 Sum: 4 R2 is the bigger Rectangle! Note: All characters in boldface are user inputs.Add a method called multiplesOfFive to the Exercise class. The method must have a void return type and take a single int parameter called limit. In the body of the method, write a while loop that prints out all multiples of 5 between 10 and limit (inclusive) on a single line. For instance, if the value of limit were 15 then the method will print: 10 15 You can use the printEvenNumbers method that is already in the Exercise class as an example to help you work out how to complete this method. In the main method of the Main class, add a call on the Exercise object to your multiplesOfFive method that prints the multiples of 5 between 10 and 25. Add a method called sum to the Exercise class. The method must have a void return type and take no parameters. In the body of the method, write a while loop to sum the values 1 to 10 and print the sum once the loop has finished. In the main method of the Main class, add a call on the Exercise object to your sum method. Check that it prints: 55 Add…JAVA ONLY Task Create a class named PermanantEmployee with attributes empID, empName, basicSalary, and allowances. basicSalary is private attribute while other two instance variables are public. This class has a constructor with two attributes empID and empName. This class has a method calculateSalary(). This method calculate employee salary(adding basicSalary and allowances) and prints it. In this class there is another method displayInformation() which prints employee id, name and his/her calculated Salary. Create another class VisitingEmployee with attributes empID, empName, hours and salaryPerHour. Hours and salaryPerHour are private attributes. This class has a constructor with two attributes empID and empName. This class has a method calculateSalary(). This method calculate employee salary(multiplying hours with salaryPerHour) and prints it. In this class there is another method displayInformation() which prints employee id, name and his/her calculated salary. In…
- This is the question that is confusing me - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course…P1. In this question, you are provided a completed superclass – Shape (Do not make any changes to this class!). This class represents generic shapes and has several methods that you will have to override in the Circle and Rectangle subclasses, whose code skeletons are provided as well. You are required to complete these two classes so that they can correctly describe and calculate their attributes. For the Circle class, create the following: A private double instance variable m radius. A constructor that takes two parameters (in the order of color, radius). It should use the parameter for radius to set the m_radius instance variable and then explicitly call the parent class constructor using the super keyword and pass in the color parameter. A method that overrides the calcArea method of the superclass and calculates the area of the circle. The area of a circle can be calculated as 3.14 x r² (where r is the radius). A method that overrides the calcPerimeter method of the superclass and…Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…
