Tic Tac Toe Game - Random Number Generator And Two Dimensional Arrays For Game Board
May 9, 2015
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;
[Code] ....

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 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";

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();

So im making this ghost game where i display an 8x8 filled with 0s and a randomly generator five 1s in there I can get it to display 0s and add 1s, however sometimes the 1s that are randomly generated sometimes go on the same spot making it look like there are only four 1s. How would i go about fixing that?
package Grade12;
import java.util.Random;
public class Ghost {
public static void main(String[] args) {
Random generator = new Random();
int gameboard [][] = new int [8][8];
int randomx, randomy, counter = 0, sum = 0;
for(int row = 0; row < 8; row++){
for(int col = 0; col < 8; col++){
(gameboard[row][col]) = 0;
}
[code]...

I have a tic tac toe game and when i run it it works and there are no errors. but the X's and O'x do not show in the board. I know the problem is in the "gameBoard" method and its cause i am telling the code to print the same board every time but i dont know how to do it the right way....
package chap7MDA;
import java.util.Scanner;
public class chapexe7we {
public static void main(String[] args) {
char[][] board = new char [3][3];//make a game board
gameBoard(board);// call the method game board to make the board
[Code] ....

I am brand new to programming and java. I decided I wanted to learn programming so now I'm in a class. I am into my second week and my assignment is to generate 100, 3 digit numbers then add them together. I understand how vast java is, but as of right now we have only studied if/else/switch statements, I was able to get the 100, 3 digit numbers generated, but I cannot add then together.
import java.util.Random;
import java.util.Math;
public class ThreeDigitGenerator {
public static void main(String[] args) {
int sum = 0;

I am new at coding and I can't seem to figure out why my random number generator (numGen) won't let me compile. this is the game class to a game i'm making called Bagels. its very similar to the game mastermind in the sense that you have to try to guess a three digit number and the computer will return feedback giving you clues that will guess the number.
import java.util.*;
import java.io.*;
public class BaglesGame {
public static numGen() {
Random Rainbow = new Random ();
firstDigit = "" + Rainbow.nexInt(10);

I am trying to make a phone number generator. I get the following error though when trying to compile.
my post
C:JAVA_PROGRAMMING_CODEcode1RandomPhoneNum>javac RandomPhoneNum.java
RandomPhoneNum.java:23: cannot find symbol
symbol : method toOctalString(int)
location: class RandomPhoneNum
strippedNum = toOctalString(num1);
^
1 error
Here is the code so far
import java.util.Random;
public class RandomPhoneNum
{
public static void main(String[] args)
{
System.out.println("This app prints out a random phone number.");
[Code] ....
Also, how did you people know about octal base numbers? I would never have known that. What I can do to improve my math ability?

I am trying to design a monopoly board game with a class and a main program. I can not make the method to keep track of the player's position after every roll. After every roll it prints "Previous position: 0".The player should also not go over 14th spot because the board is just 15 including 0. That is what I have (just the particular method and the part from the main program which call it).
public int getpospl1()
{
System.out.println( getplayer1name() + " Rolls "
+ "Dice 1: " + getrolld1() + "" + "Dice 2: " + getrolld2() + "" );
int spot1 = 14; //The end spot
int start = 0;
int previousPosition = start;

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.

Basically this code is supposed to create an int array of 50 elements, then pull the elements listed in positions 1-6 to make a lottery draw.
Problem is it gets down to that last "For" statement and then says "duplicate local variable i." If I attempt to separate it from the previous for loop with curly braces, then it gets mad and says it doesn't know what "local variable i" even IS. So I tried changing it to "j" in the last statement and it couldn't recognise that either. I feel like I need to change the variable name in that second for loop but I'm not sure how to make it understand that the second variable is going to be outputting the values from the first variable.
public class Lottery {
public static void main(String[] args) {
// TODO Auto-generated method stub
int []nums = new int [50];
for (int i = 1; i <50; i ++) {nums[i] = i;}
[Code] ....

I'm working on a project and I can't seem to get it working. It is a battleship game, in a one dimensional array. This is as much as I got. I can't get the 'river' to display when I run the program. How I might get it to work?

public class Battleship

Im creating my 2nd project ever and its a hangman game. I created an Array that has 20 different words in it and need to create a function that generates a random number to pick a random index of the array to obviously pick a random word. I cannot figure out the syntax for the life of me.

I am trying to write a Random Number Generator that will not contain any repeat value in a given range
something this I have try so far
import java.util.Random;
/**
* This class is used to generate a
* Range of Random Number in a range from int a to int b
*/
public class RandomNumberGenerator {
public static void main(String[] args) {
int[] arr=randomNummbers(1, 20);
for(int j=0;j<arr.length;j++){
[Code]...
although this code generate random numbers but some values are also getting duplicate.So how to write a program for random number that will not repeat any integer in range?

I've been working on a personal project again in Unit 3 of my text book and this time they want me to make a random phone number generator. Here's the actual directions:
"Write an application that creates and prints a random phone number of the form XXX-XXX-XXXX.
Include the dashes in the output.
Do not let the first three digits contain an 8 or 9 (but don't be more restrictive than that), and make sure that the second set of three digits is not greater than 742.
Think through the easiest way to construct the phone number. Each digit does not have to be determined separately."
With this assignment I came across 2 problems:
1. What I tried was that since the first 3 numbers have to be a random number with no 8's or 9's I tried doing this algorithm:
int first0, first1, first2, second, third, random0;
first0 = generator.nextInt (999);
random0 = generator.nextInt (8);
first1 = first0.replace('8', random0);
first2 = first1.replace('9' random0);
The problem is that Java won't allow me to generate random numbers this way. Are there any easier ways of generating numbers that doesn't contain specific number (such as 8 or 9 in this case?)
2. I was thinking about this throughout the whole project and what if I generate a number such as 27 (less than 3 or 4 digit number) rather than 3 or 4 digit numbers? How would it show 0027 or 027 instead of 27 for the phone numbers?
import java.util.Random;
public class pp0303 {
public static void main (String[] args){
Random generator = new Random();
int first0, first1, first2, second, third, random0;
[Code] ....
RESULTS:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
Cannot invoke replace(char, int) on the primitive type int
Cannot invoke replace(char) on the primitive type int
Syntax error on token "random0", delete this token

I`m trying to make a gradebook that uses random number generator to give the score, I also need to implement student numbers and sort everything with a total at the bottom. But I cant figure out how the bubblesorting works. This is my code so far:
package karakterbok;
import static java.lang.Math;
import java.util.Random;
public class Karakterbok {
public static void main(String[] args) {
Random karakterer = new Random();
Random studid = new Random ();
[Code]...
how to sort this using bubblesort?

So I'm trying to make an applet that displays images of cards. The applet has a deck of 52 playing card images. It should shuffle the deck with a random number generator and display the first 10 cards of the shuffled deck.
With this code I have about 100 errors and I'm not sure what I'm doing wrong: I know I have to use arrays in order to ultimately display the images, but do I have to create Image objects for the Image [] cards array? I am getting many "class, interface, enum expected" errors as well as others.
import java.util.Random;
import java.awt.Image;
import java.applet.Applet;
import java.awt.Graphics;

/*
Purpose: To write the methods and the rest program. The program should fill a 4 X 4 2 dimensional array with random numbers between 100 and 200. The program should then determine and print the largest and smallest values within the array using two Methods Largest and Smallest. The program should then determine and print the number of values within the array that are even using a function called Even. The program should also enter a loop that will only terminate when the user inputs a -1 as a choice. The loop should continue to ask the user to guess a number that was randomly generated. The program should call the Findit function to determine if the number was in the array. The program should print out the values in the array when the user selects a -1 and then terminate.

The problem you have is that it doesn't produce a 4x4 array. For that you need more nested for loops.This is what I have tried so far:
import java.util.Scanner;
import java.util.Random;
public class challenged2e
{
static Scanner console = new Scanner(System.in);
public static int i=0;
public static void main (String args[])
[code]...
I get 21 errors and they all have to do with i and j.

How would I get the code to count the number of times something occurred. In the end it's suppose to count how many times I played the game and how many times I've won vs lost.
