RATIONALE
Currently, Java is one of the leading development languages used in today’s business and web applications; therefore, students who wish to make their CSIS-related careers more lucrative will want to obtain a practical familiarity with it. CSIS 312 builds on the lessons of CSIS 212 with an emphasis on programming with objects and advanced Java features. While certification is not the main goal, certification makes an individual more attractive and beneficial to potential employers, and to this end, students will want to seriously consider taking the Oracle’s Java Programmer I exam. The purpose of CSIS 312 is first to ground students more firmly in object- oriented development, and secondly to help them to prepare to pass the Java Programmer I exam. (Student’s Choice). Students should note that preparing for and passing the Java Programmer I exam requires considerable study and preparation beyond the requirements of this course. After completion of this course, it is recommended that students wishing to certify take advantage of one or more of the third party test prep programs prior to taking the Java Programmer I exam.

Write a recursive //Pseudo-code for main//Instantiate an integer array of size 100. fill the array function called printArray() that displays all the elements in an array of integers, separated by spaces. The array must be 100 elements in size and filled using a for loop and a random number generator. The pseudo-code for this is as follows:

For (int i=0; i<array.length; i++)

Array[i] = random number between 1 and 100 inclusive

printArray(integer array); //You are not restricted to a single parameter – use as many as you need

//Pseudo-code for printArray()

//Base Case

If the array is empty return

//Recursive Case

Else print the next value in the array and then call printArray() to print the next value

CSIS 312 Assignment 8 SecureRandom

Write a program that inserts 25 random numbers from 0 to 99 (using SecureRandom) inclusive into a linked-list object in sorted order and then calls the linked-list object’s print() method.
The following files are provided for you and must be used for this exercise:
·      SortedList.java
o  Modify the insertSorted() method to create a sorted list. Feel free to use any ListNode or SortedList method. If you add any new methods they must be called either directly or indirectly from insertSorted().
o  Do not modify or change any other aspect of SortedList.java.
o  ListTest.java should not be changed except to enter your name in the place designated for it.
·      EmptyListException.java which is used by SortedList and ListTest and should not be changed or modified at all.
Note: If you do not use your modified insertSorted() method to sort your list as you build it, you will not get any credit for your work. Also, if you use Collections.sort() or Arrays.sort() or any pre-written sorting function to sort your list you will not get any credit for the assignment.

Make sure that your screen shot(s) show your program running and that your runtime display shows that your program does all that is required of it. You only get credit for what you demonstrate.

CSIS 312 Assignment 7 Pair Class

Write a generic class Pair which has two type parameters—F and S—each representing the type of the first and second element of the pair, respectively. Add set and get methods for the first and second elements of the pair. (Hint: The class header should be public class Pair<f, s=””>.)</f,>

Write a separate PairTest class to test class Pair. Create 2 Pair types and test your get and set methods on the following pair types:

• Pair<integer, string=””> p1 takes Integer and String types as a pair</integer,>
• Pair<string, integer=””> p2 takes String and Integer</string,>

PairTest should output enough information to the terminal to show that your generic class Pair is able to set() and get() different types.

CSIS 312 Assignment 5 LinkedList Object

Assignment 5-1
Write a program that inserts 25 random integers from 0 to 100 in order into a LinkedList object.

The program must:

• sort the elements,
• then calculate the sum of the elements, and
• calculate the floating-point average of the elements.

Assignment 5-2
Write a program that creates a LinkedList object of 10 characters, then creates a second LinkedList object containing a copy of the first list, but in reverse order. Print out both LinkedList’s starting with the first list in list order.

CSIS 312 Assignment 4 Random Sentences

Write an application that uses random-number generation to create sentences. Use four arrays of strings, called article, noun, verb, and preposition.

Create a sentence by selecting a word at random from each array in the following order:

1. article,
2. noun,
3. verb,
4. preposition,
5. article, and
6. noun.

As each word is picked, concatenate it to the previous words in the sentence. The words must be separated by spaces. When the final sentence is output, it should start with a capital letter and end with a period. The application must generate and display 20 sentences.

• The article array must contain the articles “the,” “a,” “one,” “some,” and “any.”
• The noun array must contain the nouns “boy,” “girl,” “dog,” “town,” and “car.”
• The verb array must contain the verbs “drove,” “jumped,” “ran,” “walked,” and “skipped.”
• The preposition array must contain the prepositions “to,” “from,” “over,” “under” and “on.”

CSIS 312 Assignment 3 Payroll System

Modify the payroll system of Figs. 10.4–10.9 to include an additional Employee subclass PieceWorker that represents an employee whose pay is based on the number of pieces of merchandise produced.

Class PieceWorker should contain private instance variables wage (to store the employee’s wage per piece) and pieces (to store the number of pieces produced).

Provide a concrete implementation of method earnings in class PieceWorker that calculates the employee’s earnings by multiplying the number of pieces produced by the wage per piece.

Create an array of Employee variables to store references to objects of each concrete class in the new Employee hierarchy (SalariedEmployee, CommissionEmployee, HourlyEmployee, BasePlusCommissionEmployee, and now PieceWorker).

For each Employee, display its String representation and earnings.

CSIS 312 Assignment 2 Employee Class

In chapter 9 of your Deitel & Deitel text, you studied an inheritance hierarchy in which class BasePlusCommissionEmployee inherited from class CommissionEmployee. However, not all types of employees are CommissionEmployees.

In this exercise, you’ll create a more general Employee superclass that factors out the attributes and behaviors in class CommissionEmployee that are common to all Employees. The common attributes and behaviors for all Employees are firstName, lastName, socialSecurityNumber, getFirstName, getLastName, getSocialSecurityNumber and a portion of method toString.

Create a new superclass Employee that contains these instance variables and methods and a constructor.

Next, rewrite class CommissionEmployee from Section 9.4.5 as a subclass of Employee. Class CommissionEmployee should contain only the instance variables and methods that are not declared in superclass Employee. Class CommissionEmployee’s constructor should invoke class Employee’s constructor and CommissionEmployee’s toString method should invoke Employee’s toString method.

Once you’ve completed these modifications, run the BasePlusCommissionEmployeeTest app using these new classes to ensure that the app still displays the same results for a BasePlusCommissionEmployee object.

Make sure that your screen shots show your program running and that your runtime display shows that your program does all that is required of it. You only get credit for what you demonstrate.

CSIS 312 Assignment 1 Time2 Class

Assignment 1-1
Using the Time2 class of Fig 8.5 of your Deitel & Deitel text, it would be perfectly possible to represent the time internally as the number of seconds since midnight rather than with the three integer values hour, minute, and second. Clients could use the same public methods and get the same results. Modify the Time2 class so that time is represented internally as seconds and then use Time2Test.java to test your modified Time2 class.

Assignment 1-2
Using your modified Time2 class from Assignment 1-1, add a tick method that increments time stored in the Time2 object by one second. Also provide an incrementMinute method to increment the minute by one and an incrementHour method to increment the hour by one. Be sure that you test for cases where incrementing the second, minute, or hour moves your time into the next day (i.e., 11:59:59 PM to 12:00:00 AM).
