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?
View Replies View RelatedI 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 .

View Replies View RelatedI have a question about Frames per second in games. In a simple game i should be able to pull off 60(exactly), right? So if i have this code for a game loop:
while(shouldRun){
Thread.sleep(1000/60);
//loop code here
}
will that run at 60 fps?
The loop code takes a tiny bit of time, then it waits for (a second/60), so overall the code will be running overall since the code takes some time?
Is this the case , and if so is there a solution?
In my project i am getting this error, i couldn't investigating this error :

View Replies View RelatedSo I need to write a program that reads through a String and counts how many vowels there are and prints them out as it finds them. This is what I have so far:
if (vowel == 'a' || vowel =='e' || vowel =='i' || vowel == 'o' || vowel == 'u'){
numberOfVowels++;
}
The problem is that I can't figure out how to print out the character once it detects it as a vowel.
I've downloaded the Windows version of Java Commnunication API from java.sun.com. I extracted the zip file, placed the comm.jar at c:j2sdk1.4.0jrelibext folder.After that, i wrote a simple program to test whether i can get any serial/parallel port object from CommPortIdentifier.getPortIdentifiers();. It returns an empty enumeration, meaning that none of my ports are detected.
However I have checked that com1 port is exist using hyperterminal. I have RFID card reader and I am trying to read data from rfid card.

I am having a problem with my java program. My goal is to request the user to enter how many times they want to roll a pair of dices. Each dice have numbers 1-6. When rolling the dices, I randomly pick a number from each dice and total the number. My goal is to calculate the number of times snake-eyes was rolled which is a total of 2 and total number of times a total of 7 was rolled. Here is my code. I am calling the rollDice method to perform the random pick and calculations. The error I am getting is at the bottom of the code.
package dice;
import java.util.Scanner;
import java.util.Random;
public class Dice
{
public static void main(String[] args)
{
int numRolls; // number of rolls

I've a vertical-bar-delimited file where most elements contain text, some contain whitespace, and some are empty. Examples:

which I parse and store with
String str_arry = innline.split( "|", 17);
lisst.add( new Contact( str_arry));
and my Contact class has the constructor
public Contact( String[] str_arry) {
for( int ii = 0 ; ii < str_arry.length ; ii++ ) {
if( str_arry[ii].matches("^s+$")) {
str_arry[ii] = null;
System.out.println("hit a null");
[Code]...
I expect the for-loop in the constructor to find any elements containing whitespace characters and set them to null for subsequent assignment.And when the code runs I do see some hit-statements pop up, so the detecting part is working.
But when I then process the list and access a Contact object and test fields for nulls I don't find any ie
if( aContactObj.getfFCity() == null) System.out.println("city is null");
never prints when it should.
What's the trick? Or is my approach wrong and if so what should it be?

I am making a game and there are two problems that I have and can't seem to solve. I never made on applet before, and I'm not good with the swing components, but I am decent programming in Java.
Problem #1: the start button is in the JPanel, I don't want that, I want it to be above the JPanel.
Problem #2: I want to put images in to a JTable for organization and character selection purposes, but I keep on getting a string. Do I have to use an ImageIcon to get it to work, or does it matter?
In case you were wonder what kind of game I'm making, I'm making one of those jump games where you jump on platforms and try to go as high as you can without missing a platform. There is going to be character selection for the jumper, and the jumpers are going to be food, like a potato, a banana, a strawberry, etc.
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 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.
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.

View Replies View RelatedI'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.util.*;

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?

View Replies View RelatedI 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 have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h
My guess is too high?
My fifth guess is 16: h
*** I am unlucky this round. I give up.
Let's play!
My first guess is 10:
etc..
