Player One Type A Number And Player Two Suppose To Guess - Infinite Looping
Apr 2, 2014
Its a basic program that is played by 2 people. Player one is suppose to type a number and the second player is suppose to guess the number. However after I test it out, and if I guess too low or too high I get stuck in "Your guess is too low, try again." infinite loop, what is wrong.
import java.io.*;
class GuessingGame
{
public static void main (String[] args) throws IOException
{
BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in));
String firstPlayer, secondPlayer;
int firstInput, secondInput;
int guessCount = 0;

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

I am trying to create an MP3 player with a totally customized look and feel to it. I know how to do this with .net, but I must be missing something in Java.
I want to be able to NOT have to present the user with the default mediaPlayer.getControlPanelComponent() in order to control the media player. I want to be able to code it to when the user clicks on my "Play" button, I can tell the player to play the song, and so on.
so far I get this far:
try {
player = Manager.createPlayer(playit.toURI().toURL());
player.start();
//Component c = player.getControlPanelComponent();
} catch (IOException | NoPlayerException ex) {
Logger.getLogger(TagTester.class.getName()).log(Level.SEVERE, null, ex);
}
...but cannot seem to find out where to go from there.
If familiar with AxWindowMediaPlayer in .NET, I am looking for something similar to:
AxWindowMediaPlayer.Ctlcontrols.play()
when my "Play" button is clicked.

So I have a player an enemy and enemy bounds the enemy can go. I need to have the enemy track my position and when I go into the position (I am using a collision method for this) the enemy comes over at a speed of 1. My problem is the enemy jumps to me and then follows at speed of 2 (2 is the player speed). The code is wrong this is why it is jumping and I have my other problems. so my question is what is a good solution for this? I am trying to make a method to track playerposition() so what I am thinking I could do is find x, y of player then store those into an array and return the array to Enemy so he tracks.
player.java
public class Player{
int x = 100; // Location of player
int y = 200; // location of player
int xa = 0; // Representation of where the player goes
int ya = 0; // Representation of where the player goes
private int speed = 2;
[Code] .....
Please note this is not the entire code I have cut some things out that did not need to be there. Also, the code is just to get an idea of what I was thinking of doing. The ideas that are came up with are not meant to be a reflection of what I already have but, what I could add or replace.

I have already tried every possible way for removing this bug but all failed. The problem is that sometimes my player passes through the map tiles, i mean, the algorithm is like -- if not colliding, move in required direction; else if colliding, move in opposite direction. But sometimes the second condition fails i dont understand why.
private void movement(){
left=bindObject.getLeft();
right=bindObject.getRight();
up=bindObject.getUp();
down=bindObject.getDown();
bindObject.setColliding(colliding);
[Code] .....
Where bindObject is a class which contains key bindings of following keys:-
left arrow key (when pressed) , left arrow key (when released),
right arrow key (when pressed), right arrow key (when released),
up arrow key (when pressed), up arrow key (when released),
down arrow key (when pressed), down arrow key (when released)

I am making a game with java in a program called greenfoot.My problem is that a sound won't play when the player dies and a Game Over screen pops up..
- I have saved the audio file in my sound map of the scenario
- Applied the good name of the file
- tested the sound effect and it's working
this is my code:
public GameOver()
{
setImage(new GreenfootImage("GAME OVER", 100, Color.BLACK, null));

So I am trying to create a Multi-Player game in java, and I have a Game server and a Client. They normally connect with either but I would like to add a login server so that there can be an option to go to a different world then just the main one. It will have the same map and data but will be separate from the Players that are on world one per say. Now if you are on world two I would like it to have the option for you to be able to Private message players that are on World one. That is where the login server comes in to play.
I am still new at Java and would like to be able to understand Packets and how to handle them more clearly. So far I have gotten the basis of the login server connected to the server and the client connects to the server via the login server. But I am getting a bunch of "unhandled packets" and I would like to know how to handle them. Here are some bits of the code.
package com.ls.net;
import org.jboss.netty.channel.ChannelHandlerContext;
import org.jboss.netty.channel.ChannelStateEvent;
import org.jboss.netty.channel.ExceptionEvent;
import org.jboss.netty.channel.MessageEvent;
import org.jboss.netty.channel.SimpleChannelUpstreamHandler;
[Code] ....
So when I run my client this pops up in the console:
[Tue Sep 16 16:50:56 EDT 2014][LoginServer]: Finished initializing login server.
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 15
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 41
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 74
[Code] ....
And here are the class's for Accounts:
package com.ls.net.codec.decoder.packets;
import org.jboss.netty.buffer.ChannelBuffer;
import org.jboss.netty.channel.ChannelHandlerContext;
import com.ls.bufutils.BufferUtils;
import com.ls.net.codec.decoder.PacketDecoder;
import com.ls.net.codec.decoder.handlers.AccountHandler;
[Code] ....

Alright, so I'm having problems with lines 11 - 55. I'm trying to calculate the possible tiles the clicked unit can be moved on and display it to the player.
The field is a 9 (columns) by 5 (rows) grid. A unit with can move tiles horizontally or vertically based on its movement.
Example: (unit = o; possible tiles = x) (assuming movement of 2).
[ ][ ][ ][ ][x][ ][ ][ ][ ]
[ ][ ][ ][x][x][x][ ][ ][ ]
[ ][ ][x][x][o][x][x][ ][ ]
[ ][ ][ ][x][x][x][][ ][ ]
[ ][ ][ ][ ][x][ ][ ][ ][ ]
I tried to calculate movement by finding out what column the unit is in, subtracting the column it wants to go to, multiplying the difference by *-1 if the difference is less than 0. Then, doing the same with rows and adding the difference of columns to the difference of rows and comparing it to the unit's movement. Unfortunately, with my code, it seems to move in any directions.
@Override
public void mouseClicked(MouseEvent e) {
if (Main.cards.size() > 0) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
int startingColumn = 0;

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;

How to start and structure my program because i am fairly new to the program but want to try to make a game. My idea of the game is it generates random numbers between 1-100 for two people and the program compares the two random numbers and declares the player with the higher value the winner like the card game war. Then it would give you an option to try again.

I have been working on this function and i can't get it to work. It's a little bit complicated so let me first explain what this is about:
1. As a little exam in my studies i have to program a halma console game with KI an stuff.
2. Everything is finished and works except for the Move-Calculation.
3. A Move is a Move from Field a to Field b which a player can perform in one round based on the game rules (Careful: We are not using the standard halma rules, we use different ones).
4. Class Move consists of the Starting Cell where the Figure before the Move stands and a target Cell where the figure will stay on at the Move end. It may include an Array of serveral Cells, the stop cells which the figure passes from start -> target since several jumps can be performed in one Move.
Valid Examples for Moves:
a -> b (From Field a to Field b)
d -> f through g,h,i (From Field d to Field f through the Field g,h,i
My Move Calculation where all possible Moves are calculated for a given figure consists of 2 parts. An expand() function which will generate all possible moves (works perfectly) and a jumpFix() function which isn't working properly.
Example:
After expand() I'm getting something like that:
a -> b
b -> c
c -> d
s -> t
This is however not finished, because the first 3 Moves are actually 1 Move. Because the player can Move from a -> d in one turn because those 3 are consecutive Move. The fixed Move would look like that:
a -> d through b,c
jumpFix() is also perfectly working for that situation, however there is one specific situation when it doesn't work. Let's say we have this situation.
a -> b
b -> c
c -> d
b -> e
e -> f
f -> g
s -> t
Then the only valid jumpFix() output would be:
a -> d through b,c
a -> g through b,e,f
s -> t
However i can not get it to work yet. Note: It definitely needs to be iterative, not rekursive else i would get an StackoverflowError.
This is my current Code of jumpFix():
Java Code:
/**
* Takes a look into all calculated moves and finds those which should be seen as one move, but are still considered to be more than one move (several jumps in one move)
*/
public static List<Move> jumpFix(List<Move> moves) {
Set<Move> result = new HashSet<Move>();
Set<Move> remove = new HashSet<Move>();
int lastSize = -1;
// repeat action until no moves could be merged
while (lastSize != remove.size()) {
[Code] ....
How to implement the special case where a Move splits into 2 or more branches and jumpFix() able to handle this case.

I am currently making a video player which allows users to open/play videos which are stored on their computer. I am using JavaFX for this.My problem, is that sometimes when I click the button to load a video, a java.util.ConcurrentModificationException is raised. Other times, it's perfectly fine.I put the calls to .loadAndPlayMediaA() and .prepareMedia() (see below) inside a .runLater(Runnable) to try to prevent this, but it has not worked. My Code (below) is called by a listener on a button, "testButton". I have a class called JfxMediaPlayer which holds the method loadAndPlayMediaA(), and a class called MixingDeck which holds the method prepareMedia()
testButton.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent arg0) {

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 just started my first programming class and I'm already playing catch up. It's a hybrid and the lectures are really short and fast paced that I don't entirely understand what is going on. I also got my textbook late (I was on the waitlist so didn't want to commit to buying early), so it's been a rough couple weeks.
Basically, I'm supposed to simulate a rental service transaction where the user will input numbers 1-4 to indicate which equipment they want to rent and input either H/h or F/f to indicate if it's for a (H)alf-day or (F)ull-day. I think I'm getting stuck in an infinite loop because every time I enter run the program to test the conditions in the loop, the console returns the "invalid choice" statement that I created in case the user inputs numbers less < 1 or > 4.
import java.text.DecimalFormat;

I have a Stream instace which produces values using an infinite Supplier (it supplies values taken from an electronic sensor -- so unless the battery is low, the sensor will provide "for ever").
The stream is processed by a Collector using Stream.collect() (e. g. imagine that the values from the sensor should be averaged; in fact what it does is a bit more compliacted maths).
The problem is that the collector does not produce a result but hangs up, as the supplier does never stop providing more sensor values.
So what I need is a limitation rule that stops the stream. While there is a Stream.limit(long) method, it actually does not solve my problem as in my case it is not practical to stop after a particular count, while I actually want to stop streaming when the sensor value exceeds a particular limit etc. (hence, voids an arbitrary rule).
To sum up, what I need is Stream.limit(Predicate), i. e. the stream will stopped once the predicate becomes true.
Unfortunately I did not find anything like that in JRE 8.
Is that planned for JRE 8.1 or JRE 9.0? Or is there a known (and sophisticated) workaround?
