How To Avoid Keyboard Auto-repeat
Oct 8, 2014
I wanted to make a small program to move a small rectangle by pressing the WASD keys. The program works, except that when I hold a key to move the rectangle, after a second, auto-repeat starts up, and the rectangle motion accelerates. I want to prevent automatic repeat to activate, so that the rectangle moves at a constant speed when I hold a key and stops when I released. Here is the ButtonMotion classe :
import java.awt.event.ActionEvent;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JButton;
import javax.swing.KeyStroke;
[code]....

I am working on a project named as "Auto Click and Populate". This is link is like online feedback form / surveys which we program. I have a link with me which is mentioned below and there will be a counter box which will hit the link that much number of times.
Inputs:
-A text box having this link.
-A numeric box having counter number i.e. the number of times the link should be processed.
-A button named as process which will INITIATE the process.
Now say if I input 10 into the numeric box; the attached file contain link should be processed 10 times and the question which is coming on the link should be answered randomly out of the options which are present. For ex: When you will hit a link; the first question will be gender in that 3 options are present "Male", "Female" and "Prefer not to answer"; either of 1 out of 3 should be punched automatically and proceed automatically ahead. The punch(es) will be stored in database which is maintained at my end.I have done research and till now found the code for auto click only and not for auto process.

My question is how can I make the program repeat until the user enters the number 4 to exit?
/**
* Write an application for a furniture company; the program determines the price of a table. Ask the user to choose 1 for pine, 2 for oak, or 3 for mahogany. The output is the name of the wood chosen as well as the price of the table. Pine table cost $100, oak tables cost $225, and mahogany table cost $310. Also ask the user to specify a
(1) large table or a
(2) small table.
Add $35 to the price of any large table and add nothing to the price for a small table. Display the output. Your program must repeat until the user chooses to exit.
*/
import java.util.Scanner;
public class Wood {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
System.out.println ("Table Prices");

I'm struggling with that piece of code, my intention is to check for the object I want to add before adding it, so there won't be any duplicate on my list. I'm not sure how could I do that, since I'm working with objects.
Person is a class with few parameters such as id, name, and few others.
I guess I should search for a person with the same id, since that has be unique, but can't get it right.
private ArrayList<person> model= new ArrayList<>();
//...
if (model.contains(person))throw new IllegalArgumentException("duplicate");
else model.addElement(person);

I'm using EclipseLink, WildFly, EJB, postgresSQL and JSF.I'm trying to persist some countries and their localities.So I've:
- Two entities Countries and Localities in which I specify respective columns and relations.
- Abstract Session beans for entity classes: AbstractFacade providing basic crud methods and entity manager.
- Two concrete session bean for entity classes: CountriesFacade and LocalitiesFacade.
- A JSF managed bean named geoJSF.
- A JSF page with a form allowing to insert new country and localities.
In geoJSF I'm injecting via EJB CountriesFacade as property named cf and LocalitiesFacade as property named lf.For the actual inserting country and locality I'm using geoJSF.country and geoJSF.locality. When the form is submitted I'm simply doing:
this.cf.create(this.country);
this.locality.setCountry(this.country); //<- this throw an exception (unique constraint violation) due to the attempt to reinsert this.country
this.lf.create(this.locality);
I disabled all cascade among relations definitions.Based on what I know this.country should appear detached to entity manager so, setting relation the entity manager try to re-persist it.

I need my Java program (I'm working in Eclipse if it matters) to detect if an image is a portrait or a landscape, but since i am directly downloading them from my camera they only have it written somewhere in metadata, the image width and height is the same for landscape and portrait. I have the rotation code and the rest of the program working, but I need to somehow get a variable (for example integer one) to tell me if it is a portrait or a landscape image. I tried getting to the metadata but my Eclipse decided that import com.drew.metadata.Metadata; cannot be resolved.
BufferedImage image = ImageIO.read(new File(imagePath, imageName)); and after I get the variable "orientation" it looks like this
int orientation = ???;
BufferedImage newImage = oldImage;
if (orientation>1){
newImage = rotate(oldImage);
}

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.
But while second frame coming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.
So its creating a bad flickering effect on screen and its not suitable for my application.
I want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.
Here is my source code.
1st Frame:
public class Welcome extends JFrame {
JFrame f;
JTextArea nameField,nameField1;

The method I am trying to successfully write is startsWith(String s1, String s2)
The intention of the code is to return true if s2 starts with the string s1, and false otherwise. For example,
x.startsWith("Maplestory","Maple"); Should return true.
This code partially works, depending on the values entered into it. When it is supposed to return true, it does do this. When it is meant to return false, I get a StringIndex OutOfBounds Exception.
public class CC02{
String remove1(char c, String s){
String to_return="";
while(true){
if(s.equals(""))
return to_return;
[Code] ....
The method I have written uses one other method from my code, which is "reverse". Any way to return false without getting this error.

I have a practice program (written with NetBeans IDE 7.4) that calls methods to:
(1) fill an array with user input values
(2) sort the array values into ascending order
(3) print the array in assorted order.
(4) print the array without any duplicates
Method (4) prints the contents of the array without printing any duplicates. That is, if a number in the array has already been printed, it will not be printed again.
Method (4) seems to work, but may be inefficient or I may have done too much work making it difficult on myself or making the logic too confusing.
Is there a better way to do this WITHOUT using built-in functions in Java's library?
(Such as writing this method using for loops and counter variables: As practice I am supposed to avoid using Deleting functions for duplicates)
Here is my code:
public static void Duplicates(int [] array){
int duplicates = 1;
String Output = "";
for(int i = 0; i < array.length -1; i++) {
if (array[i] != array[i+1]){
duplicates ++;
[Code] .....
