Task $1-$ The Stack Class

In the lecture for this unit, you saw how to create a Stack using an array that held int$-$type items. For this task, you must use the code shown in this unit to create a generic Stack. By making it generic, it should be able to hold any data type. In C$++$ we call this a template in Java, a generic.

C$++-$ You should use a primitive array and not a vector. You should also note that a template class should have all of its code in a header file. Separating the code into $.$h $/.$cpp will create problems for you.

In the lecture for this unit, you saw how to create a Queue using an array that held int$-$type items. For this task, you are to use the code shown in this unit to create a generic Queue. By making it generic, it should be able to hold any data type. In C$++,$ we call this a template in Java a generic.

C$++-$ You should use a primitive array and not a vector. You should also note that a template class should have all of its code in a header file. Separating the code into $.$h $/.$cpp will create problems for you.

Java $-$ remember that you cannot create a generic array of primitive types, so you will have to use an ArrayList instead. Since you have to use an ArrayList you should treat it as if it were an Array. This means it should have a fixed size.

Queue functionality

Constructor

Queue$()-$ Initializes the Queue.

Public Functions

boolean enqueue$($T item$)-$ Add an item to the end of the queue

T dequeue$()-$ Removes a value from the front to the queue and returns it$.$

T peek$()-$ Returns the value that the front of the queue without removing it$.$

boolean isEmpty$()-$ Returns true if the queue is empty and false otherwise.

boolean isFull$()-$ Returns true if the queue is full and false otherwise.

void clear$()-$ Clears the queue and initializes it's variables.

C$++-$ Of course, the return type should be bool, not boolean

Task $3-$ Using The Stack And Queue

This is a link to a file called palCheck that contains a list of phrases.Links to an external site. Some of these phrases are palindromes. A palindrome is a word or phrase that is spelled the same way forward as it is backward. A simple example would be hannah. Of course, many of the phrases are much more complicated.

Using the stack and the queue, you are to determine which phrase is a palindrome and which is not. The strategy here is that you would do the following.

In main, create an instance of a Stack and a Queue.

Read a line from the file

Save the line to another variable to preserve it

In a loop, push and enqueue each character. You will only need to store off the characters and not punctuation or space characters. In other words, only characters a$-$z and A$-$Z$.$ You should also convert each character to either upper or lower case. This will make things easier for comparison.

Once you have all characters of the line in the Queue and Stack, use a loop to dequeue and pop a character.

Compare each character to each other. You should keep comparing as long as the characters are identical and the Stack and Queue are not empty.

If you get through all of the characters in the Stack and Queue and all characters match, you have a palindrome. Print it to the screen as PALINDROME: followed by the phrase

If you get to a point where characters do not match, then you do not have a palindrome. Print to the screen that it is not a palindrome:

Not Palindrome: followed by the phrase.

You should loop until all of the phrases in the file have been read and checked.

Your output should look like the following:

PALINDROME: Taco cat

PALINDROME: Never odd or even

PALINDROME: Mr$.$ Owl ate my metal worm.

PALINDROME: Was it a car or a cat I saw?

PALINDROME: Murder for a jar of red rum.

Not Palindrome: The greatest glory in living lies not in never falling, but in rising every time we fall.

PALINDROME: Go hang a salami, I$\text{'}$m a lasagna hog.

PALINDROME: Do geese see God?

Not Palindrome: The way to get started is to quit talking and begin doing.

Not Palindrome: If life were predictable it would cease to be life, and be without flavor.

Not Palindrome: Life is
