If you were given the task of defining a Java class MetaDisplay with a method static void printTable(String r), you would create code that accepts the name of a relation as its argument, runs the query "select * from r," and outputs the results as a table with the attribute names in the header. Use the JDBC API function printTable(String r).

- In C++ Language using Functions and Pointers PROBLEM: Consider the elevator in the Faculty of Engineering (5 storey). Write a program which accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The passenger can then input the target destination floor. SPECIFICATIONS: Implement the class diagram below: Inside the main method, create an instance of the class Elevator. Use the goUp or goDown methods to generate the program display.Passenger can ride in any floor (1,2,3,4 or 5). Program will prompt the user with the target destination floor. After the user input: Program will display the floors which the elevator passes through, and finally the destination floor. Elevator will not move if the input for destination floor is the same as the present floor. Program will notify the user and then terminate. Program will also terminate if the input destination is not 1,2,3,4 or 5. You’re free to format the input/output display. Observe proper…In GO language. Create a struct that has student name, id, and GPA. Write functions to create a student, modify the student’s id, and modify the student's GPA, and print the student’s information. (This is like creating a class and methods). Now create an array of three students and test your functions. You may hardcode your values if using a web conpiler. (Please hardcode the values!)This is for python For this assignment, you will write a program to simulate a payroll application. To that effect, you will also create an Employee class, according to the specifications below. Since an Employee list might be large, and individual Employee objects may contain significant information themselves, we store the Employee list as a linked list. Employee class: Attributes • Employee ID: you can use a string – the ID will contain digits and/or hyphens. The ID must be provided during object construction and there should be no mechanism to change it later. • Number of hours worked in a week: a floating-point number. • Hourly pay rate: a floating-point number that represents how much the employee is paid for one hour of work. • Gross wages: a floating-point number that stores the number of hours times the hourly rate. Methods • A constructor (__init__) • Setter methods as needed. • Getter methods as needed. • This class should overload the __str__ or __repr__ methods so that…
- Write a program that defines a class with a data member to holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on. This question related to Object oriented programming in c++In java How to compare two objects in java? for example :- take one number of long type and other is double and compare them when they are not equal and when they are equalDescriptionIn this assignment, you are required to implement an electronic programming quiz system.

Read the code. Fill in the code to compute mean1 and mean2. Notice that you are calling the same method, but with a different number of parameters. 2. Add a call to find the average of a single integer, say 8. Print the result of the call. Is the result what you expected?3. Add a call with an empty parameter list and print the result. Is the result what you expected?4. Add a method called minimum to return the minimum value of the parameter list.

Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…

It has Items with name, manufacturer (Final) and price. Provide default & Parameterized constructors. Provide getters & setters for data members. Provide A toString() method to print values. We can add several items to Store. Now create another class store which has name, city and array of Items. Provide default & Parameterized constructors. Provide getters & setters for data members. Provide necessary validation checks ( null pointer exception, index out of bounds,etc). where possible. Provide a method AddItem (Item i) which is used to add items into the store, but number of items should be less than the size of array (check for exception).
