Java Assignment. In Java, implement a min heap and/or a max heap. Include heapsort and a driver that fully tests your code. Code must be without errors.

Draw a memory map for the code you see on the next page, until the execution reaches the point indicated by the comment /* HERE */.In your diagram:• You must have a stack, heap, and static memory sections • Identify each frame as illustrated by the previous examples.• Draw your variables as they are encountered during program execution. Code: public class Passenger {private String name;private int ticketCost;private StringBuffer luggage;private static final int LUGGAGE_COST = 20;public Passenger(String name, int ticketCost) {this.name = name;this.ticketCost = ticketCost;luggage = new StringBuffer();}public Passenger addLuggage(String desc) {ticketCost += LUGGAGE_COST;luggage.append(desc);return this;}public int getTicketCost() {return ticketCost;}public Passenger reduceCost(int by) {ticketCost -= by;/* HERE */return this;}public String toString() {return "Passenger [name=" + name + ", ticketCost=" + ticketCost + ", luggage=" + luggage + "]";}}public class Driver {public static void…

5. The creeping problem occurs when a queue is implemented as an array. (a) Define the creeping problem. (b) Describe how to implement a queue as an array in order to avoid the creeping problem. (c) Write the C++ method Join for the new type of Queue described in (b) above.

Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…
