Chapter 21, Problem 6AW
Explanation of Solution
Step 1: Define a static comparator class “DecOrder”.
Step 2: Inside that function declare a method “compare” to compare the values. This method returns the value.
Step 3: Outside the method, declare a variable to hold the capacity value.
Step 4: Create an object for the class “DecOrder”.
Step 5: Create a priority queue.
Defining a comparator class “DecOrder”:
//Define a static comparator class named "DecOrder"
static class DecOrder implements Comparator<Integer>
{
//Function definition to compare values
public int compare(Integer x, Integer y)
{
//Return the value
return y...

Declare and implement 5 classes: FloatArray, SortedArray, FrontArray, PositiveArray & NegativeArray. 1- The FloatArray class stores a dynamic array of floats and its size. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the array elements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add to the array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray.

Java Code:
Create a Parser class. Much like the Lexer, it has a constructor that accepts a LinkedList of Token and creates a TokenManager that is a private member.
The next thing that we will build is a helper method – boolean AcceptSeperators(). One thing that is always tricky in parsing languages is that people can put empty lines anywhere they want in their code. Since the parser expects specific tokens in specific places, it happens frequently that we want to say, “there HAS to be a “;” or a new line, but there can be more than one”. That’s what this function does – it accepts any number of separators (newline or semi-colon) and returns true if it finds at least one.
Create a Parse method that returns a ProgramNode. While there are more tokens in the TokenManager, it should loop calling two other methods – ParseFunction() and ParseAction(). If neither one is true, it should throw an exception.
bool ParseFunction(ProgramNode)
bool ParseAction(ProgramNode)

- Tape for a Turing Machine (Doubly-linked List)”. JAVAA class named Tape to represent Turing machine tapes. The class should have an instance variable of type Cell that points to the current cell with these methods: public Cell getCurrentCell() -- returns the pointer that points to the current cell. public char getContent() -- returns the char from the current cell. public void setContent(char ch) -- changes the char in the current cell to the specified value. Don't forget the Javadoc comments. public void moveLeft() -- moves the current cell one position to the left along the tape. Note that if the current cell is the leftmost cell that exists, then a new cell must be created and added to the tape at the left of the current cell, and then the current cell pointer can be moved to point to the new cell. The content of the new cell should be a blank space. (Remember that the Turing machine's tape is conceptually infinite, so the linked list must be prepared to expand on-demand when the…arrow_forwardDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize.

- Use NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables. For example, the payrate should not be negative. Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using).

The problem is to repeatedly pickobjects from a set of objects and find out how many picks are needed for all theobjects to be picked at least once. A variation of the problem is to pick cards froma shuffled deck of 52 cards repeatedly, and find out how many picks are neededbefore you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks neededto get four cards from each suit and display the four cards picked (it is possible acard may be picked twice).
