I wrote a Chess game that uses socket to connect to another computer, and allow player vs player and player vs computer game sessions.
However, there is a problem which I noticed.
When you get the IP address of the computer in which the program is running, you are not getting the computer's actual IP, you are getting the Router's IP.
Is there a way to get around this.
So the problem is that when I go to another computer, located in a different house or lets say from my school, the program cannot connect back to my home IP, because it uses the router's ip, not the computer's ip I am running the server program.
Is there a way to get the Computer's IP, not the router's ip when summoning or invoking the get IP address method from the socket class?
When I say that the socket class is acquiring the router's ip, well that's done without my interfering...I don't know why it does that, it is somehow recognizing the router and not the computer.
The thing is that the server program is written that any client program is able to connect to the home server.
But when I run the program from a different location other than the current home, the sockets don't connect because it is somehow recognizing the router's ip not the computer's ip.
public static void f() { int n = 5; p(n, 2 * n); } public static void p(int a, int b) { int x = 1; q(x, a + b); } public static void q(int x, int y) { int z = x + y; x = 0; ... } mh_sh_highlight_all('java');
When we write x = 0; that refers to the formal parameter int x and hence it's the formal parameter that changes value. why isn't the value of the actual parameter also changing?
I have an applet that uses JPanels to draw images in. I want to include actual jpgs now instead. The applet points to a .jar file. I want to use any number of images here, do I have to include them all in the jar file or is there another way to "point" to them (like html)?
I have a question about query execution strategy ...
Scenario: let's suppose I've to query a table with a query like
SELECT F1, F2, F3 FROM MYTABLE WHERE F1 = ? AND F2 = ? AND F3 = ?.
I need to execute this query changing parameters' actual values in a combinatorial way, until a combination gives back at least one row or all combinations are unsuccessfully tried. For instance, I may have this sequence of values:
(V1,V2,V3); (V1,V2,""); (V1,"",V3); (V1,"","");
where V1, V2, V3 may by string values and V1 is always present, not null, and not blank in each combination.
A first strategy may be to prepare the statement, clear the parameters each time I execute the query, until stop condition is met.
I wonder if may be more efficient transform the query into
SELECT F1, F2, F3 FROM MYTABLE WHERE F1 = V1
and cycling over the cursor and, for each cursor row, verify if the returned tuple (F1,F2,F3) matches the combination (V1x,V2x,V3x). When at least 1 rows matches, or all combination are done, I'll exit iteration.
I want to get current Computer CPU usage of my computer and display it in Console View of Eclipse? How can I achieve this?
My template code is:
Java Code: public class GetCPUUsage{ public static void main(String[] args){ System.out.println("CPU USAGE IS: ??????"); } } mh_sh_highlight_all('java');
I added ??? as placeholder for CPU usage because I do not know how to retrieve RAM usage by Java.
I know there are Java graphics classes, and how to use them to draw images in a window, but how do those classes interact with the screen to create the image? At the very base of it all, what is the code that is passing the computer the data to display on its screen? I'm asking because I've seen several ways to do Graphics/GUIS, a lot of them involve the Graphics class, but what is it inside all of that that that makes it work? Also, is everything else involving graphics (any other graphics libraries people write) pretty much "on top" of the Graphics class or is there something else within it more basic that is being used?
for my class we have to make a rock paper scissors game using GUI boxes. Everything is working fine I'm just having trouble displaying what the computer chose. In other words, after the user selects Rock, paper or scissors, the scoreboard just pops up displaying the score. Here's the last working program before I started tinkering with it.

I have two separate java Program that run on the same computer : Program -1 & Program-2 .
Explain Program-1 :
Name of Program -1 is “InputFrame” that is a simple frame that contain a JTextField and a Button and a JTextArea .
Explain Program 2 : Name of Program-2 is “OutputFrame” that is a simple frame that contain a simple JTextArea that this JTextArea is a Instance object from a class with name of “DisplayFrame” .
This instance object from class of “DisplayFrame” added to frame of “OutputFrame”.Now I want run both Program 1 & 2 simultaneously in the same computer and when I enter a text in JTextField in Program-1 and after click on the Button “OK” that Text Entered in this JTextField In addition to JTextArea in Program-1 display In JTextArea in Program-2 .
I do not want use a share file between two Program-1 and -2 Or DataBase .I want if Program-1 run but Program-2 is not running and i enter a text in JTextFeild in Program-1 , after running Program-2 that Entered Text Displaye in JTextArea in Frame of Program-2 .(Offline Message) .Both Source code of Program-1 and Program-2 is Attached .
I am unable to open Pogo Poker with out receiving an error message saying "Oops, Java is not detected on your computer" (or something similar). I have reinstalled it several times and get the same results.
I'm supposed to write a computer based testing program using files. I have started writing however, I am stuck. I am to prompt the user to enter the file name 'test.dat" and if something different is entered then a error message should be displayed. Also the file will create an input stream for the data using the file. I am to have the user enter other information about an employee and then write the record to the file.
The program should be created so when the user enters "quit" the loop is terminated and the file is closed. I'm not asking for code. I was just giving a brief synopsis of the project. Where I am stuck is I wrote the first part of the program that creates the file; however when I enter a wrong file name the exception error message does not display. The code is below:
import java.io.*; import java.lang.*; import java.util.*; public class Project5Write { private Formatter x; public void openFile(){
I need to activate the setting 'Keep temporary files on my computer' (Java control panel/general/settings) on about 150 Windows 7 PCs in a Samba3-Environment (which does not have GPOs). We are running Java Version 8 Update 45 (build 1.8.0_45-b14) on all of the PCs. Is there a way to change this setting with the command line, a registry entry or somehow else?
I need to know the procedure for detecting a Unique Hardware ID of any computer using Java. All I want to do is once the software application is installed should not get installed using the same key...In short I want to do license for my application.
Now lets say that I want to access a method 'addInterest()' that is in the 'SavingsAccount' class I would have to do: '((SavingsAccount)s).addInterest();'
The question I have is why do I have to cast 'b' to SavingsAccount? Isn't the actual object reference of 'b' already an instance of 'SavingsAccount' class? How does the 'BankAccount' affect the object itself? I'm really confused as to what class is truly getting instantiated and how BankAccount and SavingsAccount are both functioning to make the object 'b'.
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).
I just started using java because i want to create a simple web service that will take some values from within a url and save those values in variables.
To be more specific:
For my project I use the Spring Tool Suite.
I want to be able to enter a URL in a browser.. something like "localhost:8080/test?name=Root". When I hit Enter a page will be displayed showing "Hello Root" if the name in the URL is Root or "Hello User" for any other name.
In my java program I'm changing my IP(using proxy) and sending the request to some sites. Later some point of time, I want to know my current IP address through java program itself. How to get hold of my current IP address? Also which IP address will it show? The proxy one or the original IP ?
I am trying to build an address book, and I started from what i know how to do.
public class Persona { String nome; String indirizzo; int cellulare; public Persona(String nom, String ind, int cel) { nome = nom; indirizzo = ind; cellulare = cel;
[code].....
Now I would like the program to take a string I insert on command line (for example java Cerca"Robert Baratheon") and compare it to the nome field of every Persona in the address book.
I need a java program for getting name and address matching from oracle database. I need get all the customer name and address belonging to same person even if there is slight name and address changes are there.
