I'm writing an ESP game code for class. The problem is i cant get it to cycle through the colors after each guess is entered. It stays fixed on the original random number generated.
import java.util.Random;
import java.util.Scanner;
public class Final1 {
String colorInput, computerColor;
int computerNum, right, wrong;
[Code] ....
This repeats 10x but the color never changes from the initial random chosen.
I am creating a hangman code. So the game i am creating is 2 player, first player enters the word and second player guesses. i made the code but i don't know how to restrict the first player from adding random characters into the secret word because for my project the word can only contain letters. so i need making the code so the player 1 can only enter letters.
My code is below:
/**
* Auto Generated Java Class.
*/
import java.util.Scanner;
public class Hangman {
public static void main(String[] args) {
Scanner input= new Scanner(System.in);
String player1,player2;
int wrongguessamount = 0; //keeps the count of the amount of wrong guesses
int correctguessamount = 0; //keeps count of the amount of correct guesses
int maxincorrect=6;//makes sure the user cant guess more than 6 times
[Code] .....
package guess.the.numbers;
import java.awt.*;
import javax.swing.*;
import java.util.Random;
import java.awt.event.*;
ublic class GuessTheNumbers extends JFrame{
private JButton guessBtn;
private JButton restartBtn;
[Code] ....
I am getting a strange error and it almost seems like its not comparing it to the random generated number just the guess that i entered before. Here are my error messages.

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);

I'm having some problems with the graphics of my hangman game. The graphic that's supposed to show up on the first guess (the hangman pole) doesn't show up until guess number 2. And on the eighth guess, no graphics show up (I just get a blank frame).

I will write guess the picture game. I didn't find for example 4*4 picture how to sort picture random everytime ?
For example , when game start random various are 2734856127348561 two times same picture...
We were given the assignment to program a lotto game. in our game we should do follow the following steps below, and we are supposed to use atleast tree methods. the first one to receive the array of integers and an integer and check if the int was not entered before. the user should not repeat the same number. the other method will draw all numbers of a game (quantity of numbers to draw is based on the number parameter) and returns them in an array. the last method will display the result of the game. It receives a list of all lines played and a list of all numbers draw.
these are the steps to follow:
1. Ask the user how many lines (games) the user would like to play. Each line is made of five numbers between 1 and 45 (inclusive).
2. Ask the user to enter five numbers between 1 and 45 (inclusive) for each line. The user must NOT be allowed to enter a number more than once for each line.
3. When all the numbers for all the lines are entered, the program should display all lines and asks the user to confirm the game. If the user does NOT confirm the game, the program should start all over again.
4. Draw (generate) five numbers between 1 and 45 (inclusive). The numbers should be unique within the draw.
5. Draw (generate) one number (the bonus number) between 1 and 45 (inclusive). The number should be unique within the draw.
6. Display all the lines played and the result of each line.
7. Ask the user if the person would like to play again, if so the program should start the process all over again.
I have a database of peoples names linked up to a from to enter a new employee.The form has a previous and next button that should cycle through the employees alphabetically.What im doing the cycle by now is ID which isnt in alphabetical order and just goes by the order they where entered in.
Is there any way to cycle through alphabetically instead? Is running a query each time the next/previous button is pressed the correct way or should it just grab all the names in the array. Theres probably 150 names.
I have some problem checking if a directed graph has a cycle or not. So I have a given rooted directed graph, and find if there at least one existing cycle.
For example, I have to input the Root Node, followed by a number of nodes, the nodes in the graph, number of edges, and the adjacency list representing the edges. Each entry in the adjacency list contains a pair of nodes. The ordering of the nodes in the pair represents the direction of the edge. An entry A, B means that there is an edge from A to B. Nodes in each pair is separated by a space. One input per line.
And the output should display whether the directed graph has a cycle or not.
Sample input:
A //Root Node
6 //Number of Nodes
A //Nodes in Graph
B
C
D
E
F
6 //Number of edges
A B //Adjacency list representing the edges
B C
C D
C F
F E
E B
Output:
Cycle!
Graph Representation:
Based on the illustration above, the graph has one cycle. The cycle exists in nodes B, C, F and E.
So basically I have an arraylist (names) filled with images.
Now I have a JButton on my GUI and when I click my 'next' button, it's supposed to cycle through to the next image in the arraylist. With this code I am only using it to actually see if it will set the new image, but I keep getting errors thrown at me when im trying to define the new image to be set
String shield = "C:\Documents and Settings\derek\Desktop\shields\" + names.get(1);
imgico = new ImageIcon(shield);
img.setIcon(imgico);
The error i'm getting is:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at newmay1.makegui$myhandle.actionPerformed(makegui.java:66)
Along with a ton more lines of red text, and i've tried many different ways of doing this.
Even when I simply just output to the console each item in my arraylist, it comes out perfectly as a string.
Life Cycle Call back methods(init(), destroy(),...) are not transactional by default and expecting this in coming EJB releases (EJB 3.x / EJB 4.x). I was expecting next EJB release along with Java 8, but it stays at 3.2
View Replies View RelatedThis is my code. It is running great until I enter in the final color and hit enter. I get an Array Index out of bounds error, which I show at the bottom. I have fiddled with it, by moving the all answers correct into an if..else statement, hoping it would fix it. Needless to say, it didn't work.
Also, I am trying to figure out how to make the cursor appear in each guess box. It does in the first one, but after I hit enter, I have to click in the box each time to get one.

We have to make a wheel of fortune game. Once the above information has been taken, the game can commence. The board should look very similar to the example below if the above input was used. In order to get text to align correctly, use the System.out.format(…) method. It's 14 by 4, so would I use a 2D array? I think I can get the rest done by myself but it's the making of the board I'm having trouble with. Would I need to use a 2D array?
The board is supposed to look something like this to the viewer of the program, but they need to guess the letters that are hidden in the characters. :
* * * * * * * * * * * * * *
* * * * * * * * * * * * * *
* * * * * * * * * * * * * *
* * * * * * * * * * * * * *
These are the hidden values the viewer cannot see and must guess. Therefore, each turn they will guess a letter and the letter will the revealed if the one they said happens to be in the phrase. They will have to get STAR WARS EPISODE IV"
* S T A R * * * W A R S * *
* * E P I S O D E * I V * *
* * * * * * * * * * * * * *
* * * * * * * * * * * * * *
And the concealed letters; are Star Wars episode five a new hope. The # would mean where letters stand. So there first # would be S, the next would be T - and it would eventually spell out STAR WARS EPISODE IV.
So this is the board that's used to display the concealed letter, and there a list of the hidden letters below, like hangman.
import java.util.Scanner;
public class wheelof{
public static Scanner keyboard = new Scanner(System.in);

I have the following program. In a nutshell, I creates an array of 3 consecutive ints and the user has to guess what those numbers are, knowing that they are between 0 and 7, this is from Head First Java. In the book, the code has a bug that is made on purpose and they challenge you to fix it. As you can see bellow, every time a user's guess matches a int in the array, the NumOfHits is increased by one. When the NumOfHits is 3 (the length of the array) the game finishes.
The bug is that if you guess 1 and 1 is in the array, if you type in 1, 3 times, I will increase the NumOfHits 3 times and end the game as if you had won. To solve the bug, you need to find a way to tell the program that if the user already guessed that number, it should no longer be taken into account and we shouldn't increase the NumOfHits if the same number is provided.
I "fixed" this by searching for the index of the number that matches an int of the array, and changing that index's value to 100, since the user knows that the numbers are between 0 and 7, they will not submit 100.
The result? If the user submits 2 and 2 is in the array, the value of its indexed is replaced by 100, so that if the user submits 2 again it doesn't count as a match.
Please see the comments in the code
import java.io.*;
import java.util.Arrays;
class DotCom{
int NumOfHits = 0;
int[] LocationCells;
public void setLocationCells(int[] locs){
LocationCells = locs;
[Code] .....
The code works, but for some reason, some times I get a ArrayIndexOutOfBoundsException run time error and it appears to be somehow random. This is what I saw on the command line earlier

As you can see here, 3 returned 'missed' but 4 and 5 returned hit. Since the numbers are in sequence and are only 3, it makes sense that the last number is 6 (4,5,6). You will then notice that when I submitted 3 and 4 again it returned 'missed' as expected, because the numbers were already matched earlier, but then when I submitted 6, it returned the error seen above.
Sometimes this doesn't happen at all, sometimes it happens at the 2nd guess or third, it appears to be somehow random. I'm familiar with the error message, but I don't see where I'm using an index that doesn't exist in the array. The only time I'm referencing an array index is on
LocationCells[index] = 100;
but the index variable will only hold a value if the int submitted by the user matches on of the values in one of the indexes, so how is it that I'm going over the number of available indexes?
Below is part Two the method I need creating:
This method updates the sequence of stars according to the actual English word and the guess character.
public static String updateSecretWord(String secretWord, String englishWord, String guessedChar)
{
}
Below is the example of how it should look like when I call it
updateSecretWord(“*****”, “Hello”, “h”) = h****
updateSecretWord(“h****”, “Hello”, “o”) = h***o
updateSecretWord(“he**o”, “Hello”, “e”) = he**o
I have separated characters into an array that can be accessed from any method, however, when I try to compare the inputed guess to the computers random sequence, the counter always comes back as 0 (the comparison occurs in the checkColour method).
Java Code:
package mastermind;
import java.util.Scanner;
/**
* Program Description: play a game of mastermind versus the computer
*/
public class Mastermind {
private static int block1, block2, block3;
private static String blockColour1, blockColour2, blockColour3;
[Code] ....
The counter is called colourCorrect.. But I think the problem lies more in me converting the strings (input and computerGuess) into char arrays, as if I output the values at position in the array, I get numbers (but the numbers are not character values from the ascii table).
So i was thinking about colors in java and was wondering what kinda colors are regonised by java..found this java.awt.color.. which goes very indepth with transparancy(alpha) and other formats of colors..
Question:
I wanne make a programm in java that breaks up a picture(pixels) and put it together again..Storing values of the colors and so forth..Which format of colors would be easy to start with if taking about java programming? RGB?
My assignment is for a game where there is a board of colors and each player draws a color and moves to that position on the board. It will then output how many cards total in the game it took whichever player to win. If no winner it outputs the number of cards that none won by going through. I attached the file that corresponds with my code.
This is the desired output:
Player 1 won after 7 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 2 won after 4 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 4 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.
import java.io.*;
import java.util.Scanner;
public class ProgrammingAssignment1 {
/**
* @param args the command line arguments
*/
public static int players;
public static int cards;
public static int boardlength;
public static String board;
[Code] .....
The output that I get is:
Player 1 won after 3 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 1 won after 3 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 3 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.I guess I'm supposed to set the playerPos[] to -1, but I'm unsure how.

I need to write an image to a .png with a 255-color indexed color model. I know usually do it like this: Java Code: BufferedImage img=new BufferedImage(width,height,BufferedImage.TYPE_BYTE_INDEXED,model); mh_sh_highlight_all('java'); but that doesn't work with models with 255 colors (as opposed to 256 colors). I'm fairly sure it is the BufferedImage creation that is the problem, as when I call model.getMapSize(), it returns the correct size.
The extra color added to the image's index is 15,15,15.
Should I be something other than a BufferedImage to write the image, or should I be using a different constructor for BufferedImage, or am I doing something else wrong?
I have a program I wrote long ago. I change colors of buttons at times. Here is the code:
for(int Player=0; Player < 8; Player++){
//make them all background
dealerLabels[Player].setBackground(new java.awt.Color(212,208,200));
}
//Now make the new dealer green
dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));
The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.
I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports
public class whatever extends JFrame {
JTextArea a = new JTextArea();
public whatever() {
super("Title");
add(a);

JAR after this, when I run the. JAR this button turns gray, and it happens with all the layout of the form.

I have a 30 X 10 JTable which i would like to put a border around some cells and change Background colors on others.For example i would like to put a border around cells 1,1 to 15,1 I would like to change background colours on several individual total cells.What the shortest way to color individual cells and add a border?

so i'm supposed to create a jframe with only 1 button. each time you push the button it is supposed to go from red to green to blue to gray and back to red starting over. i can get is the background to change on the first click, then the button is useless for eternity. here is my code:

I have a jtable , a customtablemodel and a customcellrenderer with the NetBeans IDE. I want to have different colors for different rows. But anytime I run the application , the rows are not painted as expected. The code snippets are provided below.
This code is from the jtable :
duesTable = new javax.swing.JTable();
duesTable.setModel(duestableModel);
TableColumn tcol = duesTable.getColumnModel().getColumn(2);
tcol.setCellRenderer(new CustomTableCellRenderer2());
duesTable.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);
this code is from the TableCellRenderer
public class CustomTableCellRenderer2 extends DefaultTableCellRenderer{
@Override
public Component getTableCellRendererComponent (JTable table,
Object obj, boolean isSelected, boolean hasFocus, int row, int column) {
Component cell = super.getTableCellRendererComponent(
table, obj, isSelected, hasFocus, row, column);
