Guessing Game Program

Feb 10, 2015

I'm in an introduction CSE class and we're working with Java. Basically I need to create a program using scanner, while loops, and pseudorandom numbers. My program is a guessing game and I will post below the code that I already have. Basically I can get the game to work and get it to ask if you want to play another game and it keeps going until you say no. But my issue is getting the statistics of the game down. I need a separate method not in main to produce this at the end of the game once the user decides to stop playing:

Overall results:
total games = int
total guesses = int
guesses/games = double
best game = int

here's my code:

import java.util.*;
public class Guess {
public static void main(String[] args) {
intro(100);
Scanner console = new Scanner(System.in);
game(console, 100);
int numGuesses = 0;
int numGames = 1;
int end = 0;

[code]....

Creating A Guessing Game In Java

Nov 30, 2014

I am creating a Guessing game program in java code. I am having an issue with the guess class and main/tester class running. The instructions for the game are The computer generates a random # and the user must guess that number in 7 or fewer guesses. If the guesses exceed 7, then the game is over and the user is asked if they want to 'play again?'These are things I need to incorporate into my code:

If Statement

A Loop of some kind
At least three imported methods
At least two methods you create
Obtains input from the user
At least two instance variables
At least two local variables
Some form of concatenation
At least two calculations

import java.util.Random;
public class Guess
{
int computersNumber; // A random number picked by the computer.
int usersGuess = 0; // A number entered by user as a guess.
int guessCount = 0; // Number of guesses the user has made.

Design And Implement Word Guessing Game

Dec 29, 2013

I have a project about programing a game in java . In this project you are required to design and implement a word guessing game. In the game, user selects one of the available dictionaries (animals, plants, technical, names, etc. ), and the program randomly chooses one word from that dictionary and displays it by scrambling the letters. The user tries to guess the word while a guess counter starts to count down (lets assume it starts from 5).

While counter counts towards zero, the program chooses -randomly- two misplaced letters and puts them into correct positions to reveal the word more and give the user a hint. However, giving a new hint reduces the total value of the question. Lets say if the initial value of the question is 500 when all letters are scrambled, it reduces to 400 after 1st incorrect guess and hint, then after every incorrect guess it reduces more. You can determine the value of the question by the length of the word. The other details of the game is as follows:

1.You must design at least three classes (for example game, scrambledword, and dictionary).

2.Dictionaries are written in text files. If you design a class for dictionary, it must be constructed by a user chosen category ((animals, plants, technical, names, etc). In the constructor, the dictionary text file corresponding to this category must be opened and read; and words in that dictionary must be read into memory (e.g. String array). You must submit your dictionaries with your code. Do not share dictionaries between friends.

3.The game will record your total points and name in a text file where a hall of fame which has different users and their total points in 10 questions. You can design and implement a class for this.

4.Bonus+5%: Put user interface modules textboxes, buttons, etc Or

a.Use class hierarchy

b.Use of thread and timers and reducing the question value by timer instead of guesses.

Broken Loop - Number Guessing Game

Jun 3, 2014

What's wrong with my code. It says 'you win' even when I guess an incorrect number. And then the 'win' message keeps repeating. I'm thinking I need a way to generate a new input? And then maybe take the 'win' message out of the loop, but that breaks it too.

Random Number Guessing Game With Three Tries (Loops)

Mar 8, 2014

I was told to write a program which generates a random number between 0 to 5 *including 5* and give the user 3 chances to guess this number:

-If the user enters a wrong number within 0 to 5, the user has lost one opportunity.
-If the user enters a number out of range, the program should prompt the user to enter a number within the range
-If the user has 3 unsuccessful attempts, the program will print the number.

I was also instructed to use :

Random randomNumber=new Random();
int i= randomNumber.nextInt(6)

I have attempted it and this is what i have so far.
 
import java.util.Random;
import java.util.Scanner;
public class Exercise1
{
public static void main(String[] args)
{
Random randomNumber=new Random();

Guessing Game (numbers Between 1 And 100) - Getting Results To Give Correct Int

Feb 10, 2015

I've been working on a program where you can interact with the computer and play a guessing game of numbers between 1 and 100. It's mainly finished, I just need to add in my comments and stuff. My one problem about it that I cannot figure out is trying to get the results to give the correct int. At the end of the game, it's supposed to return the user information about how well they did like this:

Overall results:
total games = int
total guesses = int
guesses/game = double
best game = int

best game should give you the least amount of guesses you had during a particular round of the game. Here is what I have so far:

import java.util.*;
public class Guess {
public static final int MAX = 100;
public static void main(String[] args) {
intro(MAX);
Scanner console = new Scanner(System.in);
int tempBestGame = 0;

Java Program With Random Number Guessing?

Jun 16, 2014

Write I program that generates a random number and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the user's guess is lower than the random number, the program should display "Too low, try again." The program should use a loop that repeats until the user correctly guesses the random number.

public class NumberGuess
{
public static void main(String[] args) {
// Create a Random object.
final static Random rand = new Random();
// max number is the upward bound number
final int MAXNUMBER = 10;
/**
* Method should return a random number within the upward bound MAX_NUMBER.

[code]....

I get compiler error message

NumberGuess.java:25: error: ';' expected
int getRandomNumber ();
^
NumberGuess.java:63: error: reached end of file while parsing
System.out.println("You got it right in " + numberOfGuesses + " guesses.");
^

How do I fix this?

Opoly Game - Goal Of The Game Is To Reach Or Exceed Reward Value 1000

Mar 12, 2015

Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.

Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.

In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.

Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:

**o******

means that the player is at location 2 on the board.

Here are the other Opoly game rules:

If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.

If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).

If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,

Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.

Here is the driver class for the game:

import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();

[Code] ....

heres the methods:

REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:

playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.

spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.

spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.

move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.

isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.

drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.

displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.

Number Guessing Program - Computer Guesses A Number That User Is Thinking Of Within Certain Range

Mar 28, 2015

I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.

-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:

Welcome to this first-ever mind-guessing program!

Please pick a range (higher than 1 and no larger than 50): 32

You will choose a number between 1 and 32... and I will try to guess it.

With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.

-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:

My fourth guess is 17: h
My guess is too high?

My fifth guess is 16: h
*** I am unlucky this round. I give up.

Let's play!

My first guess is 10:
etc..

import java.util.*;
import java.lang.Math;
public class numguessprac1 {
// Declaring variables
public static String input;
public static int quit;
public static int guess;
public static int wins;

Frame Not Displaying

Sep 20, 2014

I created a instance of a class AddItemView, inside StartUpMenuController. I then passed it into the class, the main method is below showing that as well. However when I do this:

else if(e.getSource()==menu.addBtn)
{
new addItem();
}

I get an error, little red line on the bottom of the text. I am testing the frame at the moment to make sure it is what I want before I move on to the Controller side of it. I just want to display it and go from there.

package mainMenu.Home.DataBase;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import addItemBtn.Home.DataBase.AddItemView;
public class StartUpMenuController
{
StartUpMenu menu;
AddItemView addItem;

Not sure if this is the issue but the class I am making a new instance of is in a different package. I imported the package though.
