View RepliesI'm trying to learn how to Pause/Resume audio in an applet .
View Replies View RelatedHere I want to make a simple program where a Ball keep bouncing forever, then I add a MouseClick Listener to stop and resume thread (I mean, to stop moving Ball and to resume again). The problem is I can stop the thread using wait(), But I can not resume it. Below is the code
public class TestResumePauseBall {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public synchronized void run() {
Field aField = new Field();
[code]....
At first I think that notify() must be called from another active thread. So I add a 'class Timing implements Runnable'. Then I call notifyAll() from class Timing. But still it was failed.
After wait() called on Ball's thread, the whole frame also freeze. I can not understand why this happen?
If this test success, I will add 1 one more ball and add keyboard keys as controller of ball's movement.
Am doing a JSP project for maintaining the details of the interview candidates so now I want to know "How to read the contents of the resume and store in the database"
View Replies View RelatedI want to tell my java method to wait one second while something else is happening. Why not use Thread.sleep(x)? For me it stops the whole program and does not let that some else happen. Why not use wait(x)? It crashes. I tried using timers, but that doesn't solve the problem... Isn't there a simple "Java please wait 1 sec for him to catch up"?
View Replies View RelatedI am trying to create a gambling POS system and having problems with a method trying to get a value right after it was set. A jbutton sets another jframe visible which contains buttons. Upon action of the button, a value is set and the jframe is disposed.
private void btnPrizeActionPerformed(java.awt.event.ActionEvent evt) {
PrizeSelling prize = new PrizeSelling();
prize.setVisible(true);//create prize selection window
bin = getButton(); //gets what button is selected to load the correct prizes for correct game
prize.DBconnect(bin);//sends bin number to prize loading method
[Code] ....
As soon as btnPrize is clicked it gets the total value of the prizes selected which of course is 0 because it is ran before it is set. How can I make it wait until the window is closed before continuing?
I am new to Java but not to programming, and I wonder what command there is available in Java to put a pause in the program sequence, for instance when you display "press any key to continue... "?
View Replies View RelatedI am writing a console application that is to make use of the system editor on *NIX. For that I have written a method which writes a string to a file, launches an editor to change that file, and then reads the file again. The problem is the call to run the editor doesn't wait for that application to have closed.
Java Code: Runtime.getRuntime().exec(editorcmd + " " + tmpfn); mh_sh_highlight_all('java'); I need the program to wait for the editor to have finished.
With a simple "Hello World" application, once the println is executed the application exits and the process goes away.
If a simple Frame application is executed, the Frame is displayed, the println is executed but the application does not exit.
public class Frame3 extends JFrame
{
Frame3() {
setBounds(100,100,300,100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
public static void main(String args[]) {
new Frame3();
System.out.println("You are here");
}
}
It isn't that Java is aware an object exists because if I create a basic non-swing, non-gui object it will exit right after the println.
Q1. What is it that causes Java NOT to exit after creating the JFrame?
Q2. What type of object(s) when created will cause the application to continue running?
Q3. What would I do if I wanted the println statement to be executed only after the JFrame was closed?
Flow of this program?
public class ThreadA {
public static void main(String [] args) {
ThreadB b = new ThreadB();
b.start();
synchronized(b) {

I've got the game working just fine, but I don't like the way it starts playing the second you hit the "Run Last Class" button in Eclipse, and would really like to have the game start, then wait for the user to click a button before running the core WHILE loop. Everything is implemented in a single class, and here is the playGame method that starts the ball moving:
private void playGame(){
while (!gameover){
moveBall();
checkForCollisions();
}
All I want to do is pause before the WHILE loop until the users clicks the mouse button, nothing fancier than that! I've done quite a bit of reading, and it looks like ActionEvent may be the way to go, but I'm not clear on how to use it correctly in this scenario.
I would use the return value of a function how parameter of other function..In java is:
// the call produce "YES"
SecondClassController.funcSecondClass(FirstClassController.funcFirstClass());
In my web page I need to do something like this:
[...]
<h:outputText value="#{secondClassController.funcSecondClass(#{firstClassController.funcFirstClass()})}" />
[...]
obtain:
javax.servlet.ServletException JBWEB006007: Failed to parse the expression
@Named
@SessionScoped
public class FirstClassController implements Serializable{
[...]

I have started to create a calculator using Java SWING. I am new to this and don't know a huge amount. I don't know what to do now.
How do I add actions to the buttons? So when the button is pressed it will appear in the text area?
Where do I put these commands also? Within public void gui?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
lic class Calc extends JFrame implements ActionListener {
private JButton ZeroButton = new JButton("0");
private JButton OneButton = new JButton("1");

I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.
Here is the code:
public class Controller
{
private Model model;
private View view;
Controller(Model model, View view) {
this.model = model;
this.view = view;
[code]....
It runs but nothing. My other questions is how can I make a box that will print the results.
Right now, i'm trying to do is when a user clicks on my GUI button, it would display a text of information on the button they selected. I'm using an arraylist of objects and i'm trying to input the function inside the mouse click function. But I'm not sure how to properly display that information. Here is my GUI code. I'm working on the raven button. I have animal interface, with a parent class of Bird, and child class of Raven. How I could display this correctly...
public class AnimalJF extends JFrame {
private JPanel contentPane;
private JTextArea textArea = new JTextArea();
/**
* Launch the application.
*/
public static ArrayList<Bird> Birdlist = new ArrayList<Bird>();
public static void main(String[] args) {
Birdlist.add(new Eagle());
[Code] .....
So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.

I am attempting to get the x and y coordinate of a matrix of buttons. I have googled my way to failure and read the docs and I think I am traveling of track.
Below is where I create a matrix of buttons via Swing
public class View extends Mybuttons{
private static final long serialVersionUID = 1L;
JFrame frame;
JPanel matrixPanel, optionsPanel;
Mybuttons[][] matrixBtn;
Later in this class:
JPanel matrixPan(){
matrixBtn = new Mybuttons[25][25];
JPanel panel = new JPanel();
panel.setSize(550,550);
panel.setLayout(new GridLayout(25,25));
//creating a 25x25 matrix of buttons

In the controller class I am trying to get the index of each button in the getUnvisitedChildNode method. I need to do this so I can search the buttons around the button passed to it and check if they are been visited yet. Below getUnvisitedChildNode you will be bfs (breadth first search).
private Mybuttons getUnvisitedChildNode(Mybuttons b){
//example of some of the things I have tried
int x= Mybuttons.getComponentAt(b);
int y= Mybuttons.indexOf(b);
int j=0;
return b;
}

I'm just wondering whether it is possible to use images as a button in Java. I have two images that I want to use to create a rollover effect, is this possible? And then I would like to reset my java program when the button is clicked, is this also possible?
View Replies View RelatedI'm learning the swing options of Java, and my first exercise was the typical Chat Room. I got everything right: TextField, TextArea, the jpanel at left side and the buttons inside of it. BUT I can't order the 2 buttons (1 north, 1 south). I've already looked for answers, but didn't find anything and I tried to asked the teacher, but she was too lazy to look for the error. Here is my code:
f=new JFrame("Chat Room");
b1=new JButton("Send");
b2=new JButton("Emoticons");
public void showWindow(){
p1=new JPanel();
f.getContentPane().add(p1,BorderLayout.EAST);
p1.add(b1,BorderLayout.NORTH);
p1.add(b2,BorderLayout.SOUTH);

I am new to swing and I wanted to know how to be able to make a second row of buttons. Right now I have a text pane at the top and at the bottom one row of buttons. But I need to add another row or two of buttons. I've only been coding in Java.
public class TextPane {
public static void main(String[] args) throws IOException
{

I'm writing a temperature converter for class, and I'm done but one piece that I can't wrap my head around.My input scale radiobuttons work fine, but the output scale radiobuttons don't deselect automatically.

I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:
