If you were given the task of defining a Java class MetaDisplay with a method static void print Table(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 print Table(String r).

Java programming please type the code For this problem set, you will submit a single java file named Homework.java. You are supposed to add the functions described below to your Homework class. The functional signatures of the functions you create must exactly match the signatures in the problem titles. You are not allowed to use any 3rd party libraries in the homework assignment nor are you allowed to use any dependencies from the java.util package besides the Pattern Class. When you hava completed your homework, upload the Homework.java file to Grader Than. All tests will timeout and fail if your code takes longer than 10 seconds to complete. ProtectedFunction(string, int) This is a protected non-static function that takes a String and an int as its arguments and returns nothing. You don't need to put any code in this function, you may leave the function's code empty. Don't overthink this problem. This is to test your knowledge on how to create a non-static protected function.…
A programmer is designing a program to catalog all books in a library. He plans to have a Book class that stores features of each book: author, title, isOnShelf, and so on, with operations like getAuthor, getTitle, getShelf Info, and set Shelf Info. Another class, LibraryList, will store an array of Book objects. The LibraryList class will include operations such as listAll Books, addBook, removeBook, and searchForBook. The programmer plans to implement and test the Book class first, before implementing the LibraryList class. The program- mer's plan to write the Book class first is an example of (A) top-down development. (B) bottom-up development. (C) procedural abstraction. (D) information hiding. (E) a driver program.
Consider the following C++ class: class myFile { public: myFile(const char *fname); myFile(); void print(); }; An object of this class opens a file and keeps it open, method print() prints that file's content to cout, while the constructor closes the file. Provide a complete implementation for this class. Feel free to add data members as you see fit. The constructor must throw an exception if the file cannot be open for reading. Your function main() must provide proper exception handling.
Write a program in C++ using circular link list of online shopping cartImplement the above scenario using Circular Link List. Do Following:First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in list Display all items. Traverse the link list so that each items bill gets calculated (by multiplying quantity with price) and also calculate and display Total bill in the end. Delete an item if user wants to remove an item form the cart.
Write a C# program named Averages that includes a method named Average that accepts any number of numeric parameters, displays them, and displays their average. For example, if 7 and 4 were passed to the method, the output would be: 7 4 -- Average is 5.5 Test your function in your Main(). Tests will be run against Average() to determine that it works correctly when passed one, two, or three numbers, or an array of numbers.

Write a program that reads a set of details for a group of employees and then cansearch based on the employee number to find the employee and display his/her information. Theprogram will prompt the user to give the number of employees and then the details (employeeno, employee name, address, position). For the address, the user will give the details: house no,street, city. [Hint: Use a structure Employees and a structure Address].The user will prompt then to give an employee number and the program will check if theemployee exists and then to display his/her information.
