It is recommended that the information found in Types.txt be imported into the BOOK TYPE database in MySQL.
A "generic" data structure cannot use a primitive type as its generic type.

tables, the tables are fill, So the user can use your
database application user friendly
Retrieve all data: Given a table name, retrieve all data
from the table and present it to the user.
Average: Given a table name and a column name, return
the average of the column. Here the assumption is that
the column type will be numeric (e.g., cost column).
Insert: Given a table name, your program should show
the column names of that table and ask the users to
input new data to the table. In case of errors, your
program should directly show the MySQL errors to the
users.
Assumption 1: Users will enter data according to the
database constraints.
Assumption 2: Users will input one record at a time.
Delete: Given a table name, your program should show
the column names of that table and ask the users to
input data that they want to delete.
Assumption 1: Users will enter data according to the…

- Generics enable you to specify the exact type that will be stored in a collection and give you the benefits of compile-time type checking—the compiler issues error messages if you use inappropriate types in your collections. Once you specify the type stored in a generic collection, any reference you retrieve from the collection will have that type. Instructions Write a program that inserts 25 random integers from 0 to 100 in order into Java’s LinkedList object (you must use Java’s LinkedList class to get any credit for this assignment). The program must: sort the elements, then calculate the sum of the elements, and calculate the floating-point average of the elements. For this assignments make sure that your screen shot(s) show your program running and that your runtime display shows your random list, sorted list, sum of the elements, and average of the elements. You only get credit for what you demonstrate. Below is a sample screen shot. Your output doesn’t have to look…arrow_forwardCreate an application to keep track of a list of students and their grades in a data structures course using a linked list. You should use the C++ STL library. You need to create a class called student that contains 2 data members: name and grade and then create a linked list of objects of this class. The application should allow the user to add a student, remove a student, update the grade for a student, and search for a student. The class should have a constructor with two parameters with only the grade as optional. Remember, a user must provide the student's name in order to create an object of that class. Add validation code for the grade to make sure the grade is only A-F or '?' (grade is unknown or course is still in progress). Put all validation code in one function. Avoid redundancy. Overload the equality operator (==) -- use the string class member function compare to compare strings. Two objects of the student class are equal if the students' names are equal.
