Random any = new Random();
Scanner input = new Scanner (System.in);
try {
int maxNum, maxTries, guess;
boolean win = false;
[Code] .....
I want to make it loop again when asked, "Do you want to play again?"

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.

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]....

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.
import java.util.Random;
import java.util.Scanner;
public class GuessGame {
public static void main(String args[])
{
String choice="y";

Here is my instangable class
The application should generate a random number between 1 and 10 and then ask the user to enter one single number between 1 and 10 to guess what the secret number is
public class Guess{
//Variables
private int Num;
private int rNo;
private String message;
//Constructors
public Guess(){
rNo = 0;
message = "";
[Code] .....
Two errors are
Guess.java:43: error: illegal start of expression
public String getMessage(){

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 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();

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;

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.

So the following is my code for the Terrian Generation of my game, however the way i have it rendering all the tile rectangles as opposed to just rendering whats visable on my JFrame causes lots of lag.
These are the variables and Rectangles inside _TerrianGen.class
//CHUNK
static int chunkx =2048;
static int chunky =2048;
//RECTANGLES
public static Rectangle[][] tile = new Rectangle[64][64];
static int[][] blockType = new int[64][64];
//0=Grass 1=Dirt 2=Stone 10=Brick 11=Coal 12=Iron 21=Gold 22=Diamond -1=null
This is the Init() code
for (int x =0; x < chunkx-32; x+=32){
for (int y=0; y < chunky-32; y+=32){
tile[y/32][x/32] = new Rectangle(x, y, 32, 32);
blockType[y/32][x/32] = -1;

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.");

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.

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 char[][] board = new char[3][3];

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;

I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.

Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "

I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.

I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.
Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.
After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.
The output of the program should something like this:
John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67
Code:
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;
