Using Timer To Close A Class Called By A JFrame?
Nov 26, 2014
I am making a simple battleship program, you have the menu and click Start to get the board with the bombs (4 buttons as of now) Each button has either a bomb or a defualtbutton. I created my button so it can't be unselected. The problem is I have the button in a Class.java and I want that to close in a period of time. What do you recommend using?

package battleship;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GridBagLayout;
[code]....
I can call the clas in my main jFrame but I want to close the class after a certain time.

I have added a windowListener to my JFrame but for some reason it is not being called when I click X to close the window. I need to send a message to a server to notify it that the client window is closed. Some code snippets below (some lines excluded for brevity):
public class ChatGUI extends javax.swing.JFrame {
....
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); // I have all the window constants here but has no effect other than closing the window without calling the listener...
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosed(java.awt.event.WindowEvent evt) {
formWindowClosed(evt);
}
});
....
private void formWindowClosed(java.awt.event.WindowEvent evt) {
[code]....
This is resolved, needed to use...
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
formWindowClosing(evt);
}
});
... instead.

I use the right term, release resources because after clicking the close button, the DOS prompts becomes unresponsive. So I have to close the DOS prompt, then reopen it, then type in the path again for the Java folders. Can you check where did I go wrong with my code? Is my placement of the WindowListener and WindowAdapter incorrect? Please refer to my code below:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class Proj6exe1 extends JFrame implements ActionListener
{
DataOutputStream dataLabas;
JTextField rainFallField;
JButton submit;
String strRainFall;
JPanel proj6Panel;
[code]...
I have other programs where the placement of the WindowListener and WindowAdapter are as exactly like this (within the class constructor block) where they close correctly and some that behave like this, that renders the DOS prompt unresponsive.

i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.
1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.
2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.
So i created 2 classes, one called Coin.java & the other CountFlips.java,
PHP Code: package test;
public class Coin {
private final int heads = 0;
private final int tails = 1;
private int facetype;
private int flips;
[code]....

I made UpdateInmateDisplayer a Singleton so that I could access it from the private class ButtonHandler. It works to display the first inmate's number on the screen but when I close out the window and click the Book Inmate button in CurInmatesDisplayer again, it only shows a blank window. I've tried adding the components again from the ButtonHandler in CurInmatesDisplayer but it doesn't work.

I am looking for a timer class that can measure how much time has passed since the timer started (like a stopwatch). I don't wan't to use the swing timer because then I would have to create an ActionListener that increments a variable every time an event is created and that seems like too much work for the simple things I want to do. I just want it to have methods for starting the timer, stopping the timer, pausing the timer, restarting the timer, and getting the time.

I am trying to make a stopwatch using the timer class and JButtons. When I run my program and I hit start the time stays at zero. What I want my stopwatch to do is when I press start it shows the number of seconds that have passed. The start button will then become disabled and the stop button will be the only button able to be pressed. When you hit stop it should enable only the start and restart buttons. Here is my code.
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class StopWatchPanel extends JPanel
{private final int DELAY = 1000;
[code]....

Write an instance method, contains, that has one explicit parameter of type Rectangle. The method should return true if every point of the rectangle determined by the explicit parameter is on or within the rectangle determined by the implicit parameter. It should return false otherwise.
This is what i did so far?
public boolean contains(Rectangle other) {
Rectangle intersect = Rectangle.intersection(this, other);
if ((intersect.left == this.left) && (intersect.bottom == this.bottom) && (intersect.width == this.width)
&& (intersect.height == this.height)) {
return true;
} else {
return false;
}
}

My java class doesn't execute a shell sript, I had given the java io file permission read and execute over the script shell to the user who execute the java class, also I executed the script shell in the console each RAC server using oracle user session and the srcript shell works. My team DBA told me that " The user server process is oracle". My script shell resides in all RAC server file system the last result looks as follows:
/home/mydir/dir2/mybin/compacta_archivo.sh
No Funcionando!!
java.io.IOException: /home/gi91591/reppostpago/bin/compacta_archivo.sh not found
[Code]....
of course, the script file exist on my file system, it has the suitable permission as the test result i got each time I executed on the console. My Oracle version is 11.2.0.3.0 on Rac ASM.

I need to work on this "Dice" program. I've done it twice already. I've also been pouring over examples on here and elsewhere online, but none of them exactly match what I'm doing, as they all say "Pair of Dice".Mine says: "Create a class called Dice to represent a SINGLE cube". It should have a method called roll() that randomly selects a number from 1-6 for the value of the dice."
It has to use java.util.random, not math.java, and it has to have numberShowing:int, roll():int, and main() all in it.The last part reads "Create a test main method for the Dice class that creates a dice and rolls it many times. Can you keep track of how many times a number comes up? Describe how or implement it in the program." I have started at this computer for hours, and read as much info as I can.

1)A factorial of a number X is equal to X*(X-1)*(X-2)*...*1.For example,3! is equal 3*2*1=6.Create a class called Factorial Algorithm which will compute and print the factorial of an integer number on the screen
2)Write a Java program to accept eight integers and a search element from the user and display whether the element is found or not.(Hint:use bubble sorting and binary search)

I have one question that suppose I am designing a Swing applications and I am using JFrame as Top level container.
So what is best
1)first Extends that class like
public class A Extends JFrame
{
//Do all stuff with Top Level container with gui
}
2)Or design like this from this source
[URL] ....
package components;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/* TopLevelDemo.java requires no other files. */
public class TopLevelDemo {
/**
* Create the GUI and show it. For thread safety, this method should be invoked from the event-dispatching thread.
*/
private static void createAndShowGUI() {
//Create and set up the window.

I'll start off by showing my full code:
Main class
import javax.swing.JFrame;
public class groupingTest {
public static void main (String[] args) {
groupWindow test = new groupWindow();
[Code]....
At the start of the groupWindow it turns yellow and it says "The serializable class groupWindow does not declare a static final serialVersionUID field of type long".

Right so I have my ItemsPage Jframe Class and I'm trying to pass my TotalPrice variable to my CashPay so I can calculate the change. CashPrice runs and works but when I try run ItemsPage it does nothing I don't even get errors. I tried to remove that small section of trying to pass the variable to CashPay and it worked perfectly so I 100% know that's the problem. This section "public ItemsPage() { Pounds = ""; //super();
Scanner sc = new Scanner(System.in);
CashPay sendTotalPrice = new CashPay();
//System.out.println("Enter your amount");
TotalPrice = sc.nextDouble();
sendTotalPrice.printTotalPrice(TotalPrice);
"
Here is complete code for both classes, I'm using GUI builder.
import java.awt.BorderLayout;
import java.awt.Checkbox;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
[code].....
