Tank war game thats ran over a network and is multiplayer, however whenever I fire a bullet it shows on my screen but not the other player's screen. Here's a snippet of code form where i think the problem is coming from:
class Tank implements Ball {
double locX, locY, radius, angle;
int self; // index of this tank in WarPanel.tanks
public boolean turnL, turnR, forth, back, fire;
boolean prevtL, prevtR, prevfo;
Color color;
[Code] ....
I have a program thats ran over a network and is multi-player. However whenever I fire any bullets they do not fire on the other clients screen. Here's the code
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import javax.swing.*;
import java.util.*;
public class TankWar {
[Code] ....
public void paint(Graphics g) {
g.drawImage(Background, bg1.getbX(), bg1.getbY(), this);
for(int i=0;i==400;i+=10){
g.drawImage(block1,fg1.getBlockX(),fg1.getBlockY(),this);
g.drawImage(block2,fg1.getBlockX(),fg1.getBlockY()+10,this);
}
}
This is what im dealing with right now. When i click run i only get the background image showing the other two are not showing on the screen.
I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
Here is the code from my CardLayout:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JButton;
[Code] ....
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CheckerBoard extends JPanel implements ActionListener, MouseListener {
// Main routine that opens an Applet that shows a CheckerBoard
public static void main(String[] args) {
new CLayout();
[Code] ....
Once again kept to a minimal.

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/MyServletPDF?username=TEST");
response.setContentType("application/pdf");
dispatcher.include(request,response);
%>
While debugging everything is going through... even it passes through the last line. But the pdf is not launching... showing only a blank screen in its status bar as "Connecting"... Earlier it was launching.. but suddenly this issue is raising up. Is there any IE settings need to be checked?
I am currently making a 5 card stud game for my Java Programming class at my highschool. I am deciding to go a little above expectations and make my poker game a little more fun than just comparing a few cards. However I want there to be text that is changing on my screen, but the repaint() is not the most reliable way to make the screen update, I am wanting a way for have the program constantly update the screen so that if I do something like someLabel.setText("Text"); then the text will update automatically whenever it is changed.
Here is my declarations and main/constructor method
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Random;
public class FiveCard extends JFrame implements ActionListener {
[Code] .....
Here is the method addMainPage, which is called in the constructor. Whenever the enterButton is pressed, the actionListener directs it to loadBoard();
I use GridBag Layout, so to skip through all of the constraints
public void addMainPage() {
for (int i = 0; i < 4; i++) {
players[i] = new Player();
}
Icon cardBackImage = new ImageIcon("back.gif");
[Code] .....
Game intro is a method that changes the text of a label every second using .setText(), however it does not work because the enterButton is pressed, then after loadBoard() and gameIntro() is ran, it repaints the frame with the board objects and the gameIntro's final .setText() command.The action listener is simple...
public void actionPerformed(ActionEvent e) {
if (e.getSource() == enterButton) {
players[0].setName(playerNameField.getText());
loadBoard();
}
p.repaint();
}
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));
Greenfoot.playSound("fail-trombone-03.wav");
Greenfoot.stop();
}
This is code for a game I am making where you are a character at the bottom of the screen dodging falling rocks. I was wondering how to add in the falling rocks. I think I need to use Timer and an ArrayList but I am not sure if that would work and not truly sure how to go about doing it.

I have tried each and every thing in all the other answers. Like setting chunked to false, changing parameters, changing http1.1 -1.0. I am just writing a sample client to compare it with my real time client. Following is the code of client:

import java.rmi.RemoteException;
import org.apache.axis2.AxisFault;
import com.webservicemart.ws.USZipStub.ValidateZip;
public class UsZipClient {
public static void main(String[] args) {
[Code] ....
And Following is the error :

I want to make a service like Spotify, where I can stream music that I have stored on my computer (in this case server) to my laptop or phone.
* What would be a suitable format for this?
* How would I actually stream it? I want to stream, not download and then play, I want to play the music while downloading.
This question has confused me because "Errors" are capitalized and I'm not sure what they mean.
To me this question is false. Sockets can be used to transfers file over a network.
I can't see why this wouldn't work. The code looks fine to me.
I don't think this is true unless you're using the mouseEntered() or mouseExited() method. But again, I'm not sure.
I think this is true, I don't know what else could have listeners.
They're only worth a few marks each so the answer is only suppose to be a line or two. They are all true or false questions that require an explanation.
I am trying to develop an application which will be showing a TimeSeries graph(related library JFreeChart) displaying network activity related to a particular network interface embedded in a JFrame.I have created a JPopUpMenu which is having containing a list of JMenuItems showing network interfaces as their String values.Menu is popping up correctly
Further I am selecting a JMenuItem related to a particular network interface to show network activity in TimeSeries graph.On selecting a JMenuItem I can see that graph is moving on constantly but not able to see any network activity.
Pasted the code below :
package com.ankit.analyser;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.Window;
import javax.swing.JFrame;
[Code] .....
Further I can see that packetArrived method of PacketListener is not being overridden by class PacketHandler as I am not able to see data packets on console and static list in main class is also empty.
I am learning few concepts in servlets. And i came across this doubt. We used to send data over network using httpsession as below.
HttpSession session = request.getSession();
Object obj = new Object();
session.setAttribute("object", obj);
And get the data in JSP with below code
<%= session.getAttribute("object")%>
However I am not sure whether HTTPSession is serializable or not.
How HTTPSession works?
Suppose you are given a computer with 1GB RAM. The disk of this computer holds a 10GB file containing random numbers. Propose a technique for sorting the file without using the disk or network or virtual memory. Outline your approach, propose an algorithm, and implement the algorithm. What is the algorithmic complexity of your algorithm.

View Replies View RelatedI got my first project in which i need to receive some data from multiple client on network regularly(say every second) and then process that data and stored it to the database and then GUI needs to be created which display data accordingly.
While thinking for the design i thought blocking queue to implement the same. Like producer receive data from the port into a string builder and put that into the LinkedBlockingQueue. Consumer will take this data , process some work on it and store it into the database.I am using sybase ase 15 as a database.
My question is as i am receiving data very frequently which require insertion , updation and search almost every second into the database. What is the best way to improve the performance.
say i have 2 types of data is coming one having keyword 'Alarm' and other having 'ceased' so i need to use something like this
common fields in both is name and number.
if (ceased)
search into the database for particular event for which this ceased receive using name and numbe rand update the another field into it Also make separate entry for it
else
make a entry
Also as i am using 2-3 thread for consumers and thread = Number of client for the producer. So i thought to use synchronization at the consumer side which writes data into the database such that only 1 thread can write it.

I have a program that records and reruns network traffic. It was developed in C and runs in my case under Windows 7 Professional but will run almost anywhere. I have observed a lack of stability.
First I have a JAVA stand alone GUI program that runs the program as follows:
g11_bttn_start_script_capture.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
URI uri = null;
URL url = null;
String tempstr = "";
tempstr = "-s " + g11_txt_PATH_portnumber.getText() + " " + g11_txt_scriptname.getText() + ".both";

Basically it launches the executable t3drive, hangs arounf so it gets a chance to start, and then connect to it via the embedded browser.
It frequently works, sometimes launches in the browser but then freezes, and sometimes fails to start at all.
t3drive works 100% of the time if I run it under cygwin and I can reliably connect to it using any browser.
Why this might not be stable? Just looking for a direction of what to try next.
Yesterday, I established a connection with oracle 12c, codes is here:
ods.setURL("jdbc:oracle:thin:c##mytest/myt@//myhost:1521/orcl");Connection conn=ods.getConnection();
where "c##mytest/myt" is username and password. It worked well.
But, today, "IO Error:The Network Adapter could not establish the connection" appeared when I tried to run my program again.
I changed //myhost into 127.0.0.1, it worked again.(Before I did this, I checked lsnrctl and regedit and firewall....., no difference)
Here is my question:
1) What happens between //myhost to 127.0.0.1, hostname cannot be use to JDBC? If yes, how?
Besides, I have some other questions:
2) How import a *.dmp file which exported from 10g into 12c?
3)If I need upgrade 10g to 12c, what shall I do?

I want lo list all the devices connected to my network, I done like this
InetAddress i = InetAddress.getLocalHost();
byte[] ip1 = i.getAddress();
InetAddress address = InetAddress.getByAddress(ip1);
for (int b = 0; b <255;b++) {
ip1[3] = (byte)b;
[Code] ....
It prints all the connected devices, its k.. my doubt is, how to list the wired connections and wireless connections from them...
I am trying to connect a remote machine but I can't. There is a shared folder in the remote machine, when I write the path to file browser in local machine, it does not find the path specified. Both machines have successful network condition and ping each other. Also, the shared folder is opened to everyone, there should not be a permission problem, right?
