Chapter 8, Problem 26E
Challenge exercise Implement the back command so that using it repeatedly takes you back several rooms, all the way to the beginning of the game if used often enough. Use a Stack to do this. (You may need to find out about stacks. Look at the Java library documentation.)

Find out what happens when you just leave the stack alone.
Load your bag with some initial values, but do not fill it.
Your client code should give the user the option to:
display the contents of the bag using the class method “toVector”
add values to the bag
remove values from the bag
sort the bag
search for a value using their choice of either the iterative search or the recursive search - both need to be tested
Allow the user to keep doing these things until they are done.
Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well.
Each value in your array should be unique - no value will appear in the array multiple times.
Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…

Download the Singleton Exercise.java file.
Change the Deck class into a Singleton class.
Change the main method to get the Deck instance rather than creating a
new object.

- Complete the recursive drawBoxes() method so that it will draw all of the boxes in the image below. It currently only draws the first and smallest Box. Feel free to use a different shape if you do not like boxes.arrow_forwardComplete the searching and sorting algorithms in ModuleOne and ModuleTwo of the modules package. Test all sorting algorithms in AlgorithmsTest. You must build everything from scratch and cannot use any methods in other Java packages to make your algorithm. Restrictions : All classes/methods must be made by you. You are ONLY allowed to use java.util.Arrays.toString method You are NOT allowed to use any other the Java API Library classes/methods.arrow_forwardCreate, compile, and run a recursive program. Choose one of the labs listed below and program it. More details for the lab can be found in the first PowerPoint for Chapter 9. Make sure your code is recursive. You can think of recursive code this way: If you cut and paste a recursive method into another class, it should still run without problems. In other words, you cannot have any instance variables (class-level variables) that the method depends on. Choice 1 - boolean isPalindrome (String str) that returns true if the input string is a palindrome. Choice 2 - boolean find (string fullStr, string subStr) that tests whether the string subStr is a substring of fullStr Choice 3- int numDigits (int num) to determine the number of digits in the number num Choice 4 - double intPower (double x, int n) to compute x^n, where n is a positive integer and x is a double precision variable Choice 5-void printSubstr (String str) that prints all substrings of the input string.arrow_forward
- Challenge exercise Read the footnote about the Arrays. asList method. Find and read the sections later in this chapter about class -variables and class methods. Explain in your own words how this works.arrow_forwardPlease help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how room 1…arrow_forwardAdd the code to the end of your monitorLevels() method. It must become the last code of monitorLevels().

So you have # to access its items via displayList followed by TWO indexes. . . . # Extract the second item from the current sub-list into a variable called priceLevel priceLevel = . . . # Test if priceLevel is between previousPrice and currentPrice OR # priceLevel == previousPrice OR # priceLevel == currentPrice if( . . . ): # Sound the alarm.

- A for construct is a loop that goes over a list of objects. Consequently, it runs indefinitely if there are items to process. What do you think about this?arrow_forwardLet's finish working on our booking system. The last part for our booking system will be to manage multiple flights. To do this, we'll modify our program's command list. The command "create [id] [cap]" will try to create a new empty flight with ID [id] and capacity [cap]. The command "delete [id]" will try to remove the flight with ID [id]. The command "add [id] [n]" will try to add n reservations to the flight with ID [id]. The command "cancel [id] [n]" will try to cancel n reservations from the flight with ID [id]. If an operation fails for any reason, the program will issue the message "Cannot perform this operation". You can add a more helpful message to identify why the operation failed. The command "quit" will stop the execution of the program. For the sake of simplicty, let's limit the maximum number of handled flights to ten. Use the code from your previous exercise as a starting point. Note that we need to add an access method to the flight id field. PLS ANSWER…arrow_forwardWrite this program in Java using a custom method. Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game. Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an…arrow_forward
