Chapter 8, Problem 15E
Program Plan Intro
Program Plan:
- Modify the CommandWords class to recognize the "eat" command.
- Modify the Parser class to call a new method when the "eat" command is entered.
- Create a new method in the Game class to handle the "eat" command.
- Add the necessary logic to the "eat" method to print out the desired message.
Program Description:
To add eat command in zuul game that prints out "You have eaten now and you are not hungry anymore.".

PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS.
Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.
Add additional functionalites to this code. For one room add this riddle, "The shorter I am, the bigger I am. What am I?" And the only way to continue to the next room is to type, "A temper," or "temper." And for another room, a help command. For example, the user will type, "help," and they will be told where to go next so they can each the winning room.
The obvious next step is to name the stars and planets using random numbers. Names usually follow certain rules rather than being made up of random strings of characters. Choose a set of real-world names (for example, from J.R.R. Tolkien's world) and create a set of rules for them to follow. Create and implement a method for generating new names based on a set of rules and random numbers.

- Create a VisualCounter class that supports both increment and decrement operations. Take the constructor inputs N and max, where N indicates the maximum number of operations and max specifies the maximum absolute value for the counter. Create a plot that shows the value of the counter each time its tally changes as a side effect.arrow_forwardThe first application you will complete simulates a fight with the mythical greek hydra. As legend goes, if you were to chop off the head of a hydra, two smaller heads would grow back in its place. In order for our fight to have an end, we will assume that once the size of the targeted head is small enough, no new heads will grow back in its place. The goal of this application is to determine the amount of work required to kill a hydra with a single head, when the size of the head is given as input. Final output would look like this The head bag is Bag[ 3 ]The head bag is Bag[ 2 2 ]The head bag is Bag[ 2 1 1 ]The head bag is Bag[ 2 1 ]The head bag is Bag[ 2 ]The head bag is Bag[ 1 1 ]The head bag is Bag[ 1 ]The head bag is Bag[ ]The number of chops required is 7Run the program again using 4 for the size of the initial head. The work done should be 15.Run the program again using 5 for the size of the initial head. You should get the computation ended early.Run the program again using 6…arrow_forwardThe first version of Abby’s Eggs worked but was a bit cumbersome. I.e. you couldn’t edit a single parameter, you had to always re-enter all of them. Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class. Have separate methods for updating the parameters. Use a switch statement to take menu selections for updating parameters or outputting results. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated. Before displaying updated menu, “clear the screen” I got most of the code working, but I can't find a way to clear the sceen before displaying the updated menu. I tried using "System.out.print("\033[H\033[2J"); System.out.flush();", but it is not working. I am using the Apache NetBeans IDE.arrow_forward

- Please 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_forwardImplement the "Output players above a rating" menu option. Prompt the user for a rating.

Cards are to be compared using their value. They are considered the same if they have the value. One is less than the other if its value is less. Add the compareTo method that takes a Card object as a argument and returns 0 meaning the values are the same, 1 meaning the card is greater than the parameter, -1 meaning the card is less than the parameter. Create a main() that creates a Deck. Use your code from the program that dealt out Cards from a Deck and showed the hands but this time, now that Cards are comparible, show them in sorted order using Arrays.sort if the had is an array, or Collections.sort if the hand is an ArrayList. Show the hands. Document, document, document!arrow_forward
