JAVA PROGRAMMING: Write a program called TimeSymbolTables that
creates three symbol tables, each of a different implementation.
Each symbol table will contain as a key a word read from a text
file and as a value the number of times that word occurs in the
text file. Have the program fill the first symbol table with these
counts, keeping track of how long that takes using a Stopwatch
object. It then does the same thing with the second symbol table....

Here are SQL declarations for three tables R, S, and T:
CREATE TABLE R(e INT PRIMARY KEY, f INT);
CREATE TABLE S(c INT PRIMARY KEY, d INT REFERENCES R(e) ON DELETE CASCADE);
CREATE TABLE T(a INT PRIMARY KEY, b INT REFERENCES S(c) ON DELETE CASCADE);
Suppose R(e,f) contains tuples
(1,0), (2,4), (3,5), (4,3), and (5,7).
Suppose S(c,d) contains tuples
(1,5), (2,2), (3,3), (4,5), and (5,4).
Suppose T(a,b) contains tuples
(0,2), (1,2), (2,3), (3,4), and (4,4).
As a result of the...

Create a class called Employee that contains three instance
variables (First Name (String), Last Name (String), Monthly Salary
(double)). Create a constructor that initializes these variables.
Define set and get methods for each variable. If the monthly salary
is not positive, do not set the salary. Create a separate test
class called EmployeeTest that will use the Employee class. By
running this class, create two employees (Employee object) and
print the annual salary of each employee (object). Then set the...
