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.
View RepliesOk, here's what I got.

tracking the number of games played, and also when running the code, I have to press "1" twice for it to actually load up the game again.
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.

I tried this program, its guessing game. Where program decide 1 number and user will guess number. I am getting 1 problem. When user want to play game again.the random number remain same. So where i can put reset random in code..? And 1 more question if I want to write driver code for this. What should i transfer to driver code.

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..

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;

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.

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.
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;

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.

I get compiler error message
NumberGuess.java:25: error: ';' expected
int getRandomNumber ();
^

How do I fix this?
Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done. I have run into a few problems with trying to get the computer player to correctly generate 2 integers and have those two integers be a place on the game board. Here is my code so far.
import java.util.Random;
import java.util.Scanner;
public class TicTacToe {
private static Scanner keyboard = new Scanner(System.in);
private static char[][] board = new char[3][3];
public static int row, col;

The problem is what to do when the source file for a class gets too big ( a judgment call for sure). Is it possible for one class to be defined in multiple files and if so how do you do it, and is it good practice?
I do see ways to refactor into a base class or move code into a helper class but sometimes the abstraction is cleaner as a single class that does a lot of stuff. My problem is how to organize a BIG class?
I'm back with a question about the Black Jack assignment. I've created a working game that works for one round, as well as a reset button that's able to clear the board of the old hand. However the runGame() loop, which checks whether a player has played his hand seems to freeze the program the second time around
private void initNewGame(){
dealer.addCard();
for(int i = 0; i < numberofplayers; i++){
players[i].addCard(); //draws card, adds score and paints card to the board
players[i].setStatus(false); //makes the buttons usable in the players[] class
[Code] .....
I know it's probably not optimal having an while loop constantly running to check the status, but I can't seem to figure out why it freezes.
I've run into some problems with my Quiz-game program. What I basicly want it to do is generate a random number that is tied to the other windows I have for the program (I want a new random question to be generated once I have guessed on the first one). I've read about a few different ways to approach this but everything I get is a pure number generator.
I imported
import java.util.Random;
into my program but I don't know where to go from there.
I need the game to automatically proceed to the next game after the user has guessed the correct number. I don't know how to do this or what to add.
Here is my code:
import java.util.Random;
import java.util.Scanner;
public class HiLo
{
public static void main (String[] args)

a. Write a code that is written inside a body of a method named average that takes two parameters: N that determines number of terms you should calculate the average of and lowBound that is the beginning term of the geometric sequence. if lowBound is 4 and N is 3, then the average of 4, 8, 16 is calculated and returned.
My code runs fine if I set the test as 16, but I can't figure out what I could do to N to have it determine the number of terms. This is what I have so far...
public class AvgIt {
public static void main (String[]args) {
double result = average(4, 3);
System.out.println("Average is " + result);
[code]....
int[] a = new int[7];
a[0] = 0;
a[1] = 10;
a[2] = 256;
a[3] = 57;
a[4] = 33;
a[5] = -154;
a[6] = 168;

What program needs to find is the most biggest number. It does the job, but another task of the program is to find the index of that number . The second loop should do just that, but for some reason, as the loop goes further, it passes through the if statement even though answer "a[i]" is not equal to "answer". The idea is that if a[i] and answer are equal, the "i" should represent the index number.
What I am trying to do here is allow input to loop until 0 is entered for the product number. When 0 is entered, it should then dump the total for each individual product. I've tried it about a dozen different ways and have yet to be able to get the loop to function as intended. The way I have the code below, the loop will not function at all (where as before it looped, but never finished).
import java.util.Scanner;
public class Sales {
public static void main(String[] args) {
double total1=0.0;
double total2=0.0;
double total3=0.0;
double total4=0.0;
double total5=0.0;
int product;

I have a problem with my application. It supposed to store 4 different Room objects but when I entered one only it stores tat object variables into all my Array elements. I just need it to store any number of objects as long as it is less than 4.

The problem occurs after the user inputs the guess.... it either runs the for loop if guess = numtoguess and reveals the answer even if the user input is wrong.... or it always runs the first if statement in the while loop if guess!= to numtoguess... heres the code
public static void main(String[] args) {
String[] Answers = {"yes", "Yes", "No", "no"};
String Name = JOptionPane.showInputDialog(null, "Hello, What is your name?","Random Game", JOptionPane.QUESTION_MESSAGE);
String UI = JOptionPane.showInputDialog(null, Name + " do you want to play a game", "Random Game", JOptionPane.QUESTION_MESSAGE);
