I'm doing this project where I need to make a persian carpet using recursive methods. I already have my recursive what I'm trying to implement is the use of color. My method BorderColor draws a square using a random color choose from an array.
public void Cuadrado(Graphics g){
Random color = new Random();
g.setColor(colors[color.nextInt(colors.length)]);
g.drawLine(left, top, right, top);
g.drawLine(left, top, left, bottom);
[Code] ....
What I'm trying to do is getting the color from 4 different corners in order to create a new one and make a recursive call. I already tried using the method getPixelColor from the Robot() object but I quit it because is a recursive method and it may cause trouble with the recursive stack. I created this method to create the new color and then call it in the PersianRug method, but I dont have a clue on how to obtain and implement the new colors.
public int newColor(int c,int c1,int c2,int c3, int a){
int c4=((c+c1+c2+c3)%13)*a;
return c4;
}
I've found following code for Singleton Implementation from this forum, I am having a difficulty of understanding following,
1. When Singleton instance will be created, ( From which call ) ?
2. What feature of Static Inner class allow object to be singleton ?
3. How Inner Class implementation is thread safe ?
4. What will happen if variable "instance" mark as non-static, Will it still grantee singleton implementation ?
Java Code:
public class Singleton {
// Note private constructor
private Singleton() {}
private static class SingletonInner {
private final static Singleton instance = new Singleton();
}
public static Singleton getInstance() {
return SingletonInner.instance;
}
} mh_sh_highlight_all('java');

I use jboss eap 6.2 under eclipse.I perform a tutorial on EJB and I want to show the difference between a stateless session bean and a statefull session bean. I want demonstrate that the first one keep its state (if it has one) but that 2 successive don't send back necessarily the same SLSB : it send back the SLSB that is ready in the pool. But I don't suceed in obtaining 2 different SLSB by 2 successive call. The system always send me back the same SLSB.
View Replies View Relateda new java executable file which does heavy processing (batch). Development hasn't really started yet and the design phase is just beginning. Now the client is asking us to give them the minimum server specs to be able to run our application..I'm thinking this can't be done without performance testing, which will be after development. Is there a better and faster way to be able to assess this?
View Replies View RelatedMy biggest issues are as follows:
1) I'm trying to use a logarithm to determine the length of a user input number. I keep getting an error stating <> indetifier expected. I'm assuming this means that the program is not recognizing the function of a logarithm. I know that normally you can include that information in the method, but my teacher has stated specifically that each of these methods be called something else, as shown in the code.
2) I'm not quite sure I understand how to assign the numbers I obtain from the modular equation to a certain position in the array. As I'm asking the user to input any number these values can change so therefore I can't simply state that first number = this place.Here is my code:
import javax.swing.*;

I have a jar file. I need to open and see the source code in the jar file to override some of the style related code like primefaces-3.4 related
org.primefaces.component.behavior.printer.PrinterBehavior.getScript()
How do I see jar content.
I have the assignment of making an application that reads a file and then validates the contents to create a statistical report.
I have managed to have the application read the contents but im completely puzzled on how the validating works.
Is there coding in the file that put the numbers and words into the correct data types or is that also done in the application?
The application is to read the file of rugby scores and the produce the report with the amount of goals scored.
I have a jTable with one or 40 rows in it.
The problem is, also when I have only one row in my jTable, the size of the jTable is a little more bigger than 40 rows.
How can I say the jTable, that she should scale to the size of the content?
I don`t want that the jTable is bigger than the content. For example the picture below:
i have a class that creates an object made of 2 strings and an arraylist
class Users{

[Code] .....
This object then gets returned to an arraylist of these objects
static ArrayList<Users>users=new ArrayList();
My question is how can i then get the arraylist from this object to print its contents?

I'm trying to print the contents of my linked list. I'm using nodes and within those nodes it hold String data. So i want to print out the data within the nodes. Whenever i do
System.out.println(node1.data),
it prints perfectly. But i'm trying to use a method where it would loop through the list and print out the data for every node in it. when i run my print method i get results such as
Node@15db9742
Node@6d06d69c
Node@7852e922.
Here is my print method i created
Java Code:
public void print(){
Node<E> current = head;

System.out.println(current.data);
current = current.next;

I'm trying to debug a program and I need to see the values in a Bean. I tried
" system.out.println("OrderManager.java: packagePricing, packBean= "+packBean);"
but that just gives me
"OrderManager.java: packagePricing, packBean=com.voxportal.web.device.PackageBean@73dde7ae"
which I think is a reference to the bean but not the actual contents of the Bean.
Write a function that will add the contents of a String array.
1. This time the input array to your function will be an array of Strings.
2. Your function body will be similar except you'll have to convert each String to a double number.
public class SumVals2 {
String aryVals[];
double result;

Any method of viewing the contents of an .ISO in java. my searches so far have said to use the java api loopy but I cant find hardly any information on it and i have been unable to use it correctly so far. If there is no way to just view the .ISO file contents then extracting its contents and then viewing them would also be fine how to do that.

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 have a Jtable which shows contents on each row. but the row contents which are bigger than the width of the column gets shown as "BlahBlah.." (basically getting showed up as .. in the end)
User has to manually increase the width of the column to see those extra contents.For e.g if the row contents are ABCDEFGHI and the widht of the column for that row is sufficient enough to show only ABCDEF of that, then it will show up as something like "ABCD.."Now my requirement is to show the complete contents over to next column on the same row.
Note: I could simply add the code to show the widht of the column to adjust according to largest row content for that column . But unfortunately this is not what is required.
I have been doing a project of ERP solution using JAVA AWT FRAMES and MYSQL(for database purpose). Here there is an ADMIN portion, who has the authority to make PAYROLLS of individual employees. There is a Frame where individual employee details will be shown(like basic salary, HRA, no.of leaves, other allowances...etc) in text boxes.
Now what i want is to make a PDF file of that payroll, so that I can make a hardcopy of it. The idea is just like anyother online form fill-up, where at the end you submit and save (or export) as a PDF (or text file) document. But I mention that it is a stanalone project, not an online one (i think it doesn't matter though).
So the basic idea is how to make a PDF file by extracting the text field or choice contents from a frame in JAVA AWT.
