1. Create a class Employee with parameters name, id, designation, and basicSalary. Use appropriate datatypes and access specifiers. Use default constructor to create objects of employee. Write methods toset and get the values of parameters of employee. Write methods to find total salary of employee andto display the complete details of employee along with total salary. Create another class TestEmployeewhich creates array of n number of employees, uses appropriate set methods to set the values ofparameters of every employee. Display the details of each employee. (Total salary = basic salary + 80%of basic salary)
10.5 LAB: Count probations (EO) Students are put on probation if their GPA is below 2.0. Complete the Course class by implementing the countProbation() method, which returns the number of students with a GPA below 2.0. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Hint: Refer to the Student class to explore the available methods that can be used for implementing the countProbation() method. Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.2 GPABrenda Stern with 1.2 GPALynda Robison with 3.3 GPAJake Flynn with 1.8 GPA then the countProbation() method returns 2 and the program output is: Probation count: 2 Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student…
Task 1:The first task is to make the maze. A class is created called Maze, in which a 2D array for the maze is declared. Your job is to implement the constructor according to the given javaDoc. When you completed this task, write a set of Junit test case to test your code.As you probably noticed, the maze is defined as a private variable. The second job for you is to write an accessor(getter) method that returns the maze. Other information about what is expected for this method is given in the starter code. public class PE1 { MazedogMaze; /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */ publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze * using the input argument. */ }
1Declare an array to store objects of the class defined by the UML above. Use a method from the JOptionPane class to request the length of the array from the user. and Use a method from the JOptionPane class to request values from the user to initialize the instance variables of Election objects and assign these objects to the array. The array must be filled using this UMl
Create a class named "Hotel" (3 marks) - The class must have 4 attributes. (Choose any 4 attributes you want) - This class must have two constructors, Getter Methods, and Setter Methods. - toString() method should return the name of the hotel.  In the main class that has the main method: - In the main method, Create 4 objects or more from the class Hotel and store them in a normal array. (3 mark) - Create an external method that takes the array as an argument. It will add all the elements of the normal array into an ArrayList. Then, call the method to test it and print all elements data from the ArrayList
23.5 LAB: Random values (Use Python) In main.py define the RandomNumbers class, which has three integer attributes: var1, var2, and var3. Write getter method for each attribute: get_var1(), get_var2() and get_var3(). Then write the following 2 instance methods: set_random_values( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers within the range of the low and high input values (inclusive). get_random_values( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output may be: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range.
Question 1: 1.1) Implement the book class that includes data values that describe various attributes of thematerial, such as the number of pages and the name of the author. Include methods thatare named appropriately for each class to set and get the declared attribute and print anappropriate message. 1.2) Create the dictionary class that inherits all attributes of the book class with an addedattribute named definition. Definition is an integer number indicating the number ofdefinitions found in the dictionary. 1.3) Create a main driver class to instantiate and implement the above classes.
Create a class Student with following data members, name, roll, and marks as private data member. Create array of objects for three students, compare their marks but make sure allocating memory to all the objects during run time only and display the records of the student who is getting highest score.
Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() method and the equals() method. The equals() method must return true if the two countries have the same name and same area and false otherwise. 1) Write a main method, define an array of country objects 2) Display countries whose populationSize is greater than one million.
Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three private fields: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPABrenda Stern with 2.0 GPALynda Robison with 3.2 GPASonya King with 3.9 GPA then the findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9)Code:Course.java: import java.util.ArrayList; //create class Student //create class Courseclass Courses{ private ArrayList<Student> roster; // collection of Student object // class constructor…

Use NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables. For example, the payrate should not be negative. Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using). Finally, the…
