Basically i'm trying to add one more "coin" to flip. My problem is that my if-else structure isn't working correctly here's what it looks like:
if (count1 < GOAL)
if (count2 < GOAL)
System.out.println("Coin 3 Wins!");
[Code] .....
It only works correctly when "coin2" wins.How would I modify my if else structure to get the output I am looking for?
I have a design scenario here which is quite interesting and complex. I have a Java class structure as follows,
class A { class B; innerClass B { List<class C> listofC; innerClass C { String attribute1; String attribute2; // Their getter setters } } }
So I have this as an API. Now my challenge is that I need to add one more property to inner class C. i.e attribute3 in innerClass C. I need to do this without disturbing the code in class A by extending these classes or writing a new wrapper, so I can use class C with new properties .
I hope this should be achievable through any design pattern either at runtime or design time.
I am writing a program for my Java class and I have every function of the program working aside from the modify and delete button. I'm not sure how to make them work. The course material doesn't cover these functions at all.
Here is what I have so far.. which is practically nothing. If I need to post any other code I will, I just don't want to post more than needed because going through unnecessary code can waste time.
public void actionPerformed(ActionEvent e) { inventoryTotalField.setText(String.valueOf(genre[ArrayIndex].getInventoryTotal())); //add button functions if (e.getActionCommand() == "First")//if first button is clicked { ArrayIndex = 0;//set array index to the first element in the array setFieldValues(); // display dvd info on the form
i'm trying to modify and use a GUI to set the variables the setter methods. while the code seems valid to me and should work perfectly, i get ArrayIndexOutOfBounds and StringIndexOutOfBounds and respectively lines 111 and 134. i'm am not the original author of this code, all i want is to get it to work fine.
Implement a Las Vegas slot machine! The machine works as follows. First, it generates three random integers (use import java.lang.Math.*; then call Math.random()*7 to generate a random number between [a,b)) that are in the range of 0-7. Once the numbers are generated, the following rules are used to determine the prize:
- If all three numbers are equal to 7, you are winning $1,000, - If all three numbers are equal, but not equal to 7, you are winning $500, - If two of the numbers are equal to 7 and the third one is six, you are winning $400, - If two numbers are equal, you are winning $100, - Otherwise you are not winning anything.
And for that I wrote:
import java.lang.Math;
public class Assn1_2150130 { public static void main(String[] args) { // Generate three random signle-digit integar from 0-7. int n1 = (int)(Math.random()*7); int n2 = (int)(Math.random()*7); int n3 = (int)(Math.random()*7);
[code]...
But I just can't figure out a way to print out the "YOU WON NOTHING." independently.If I say that n1!=n2 && n2!=n3 && n3!=n1, and then write another line of println. It gives out the number as well as the "NOTHING".
Is it possible to map URL's with independent view dir structure? If so how?
My goal is to simply point an url to a specific view file:
i.e.
[URL] ....
to not/default/path/views/main/index.xhtml and www.myserver.com/application/admin/ to not/default/path/views/admin/index.xhtml
A couple solutions I found so far where:
Solution 1
PrettyFaces
I just didn't wanted to use a third party solution. This is my best solution so far.
Solution 2(a JSF solution):
navigation rule entries in the faces-config.xml file.
A bean is required, not a bad thing in above example but not great in combination with static navigation like:<h:commandButton action="index"/>
Solution 3 (another JSF solution)
Resource Library Contracts This forces me to work in the contracts file.
None of the solutions gave me a clear solution except prettyfaces.
Are there some elegant native JSF solutions ? Something flexible and reusable? Something like a mvc controller i used to use in php applications. In this controller I was able to add a template file in the constructor and an content file in specific function. Custom paths where no problem. I didn't want to use mvc nor the php language in this project.

How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?
lst contains list of objects and one of the objects contains the property bDate(Timestamp) which has the value 28-2-1989 00:00:00.0, now I just wants to change the value into 28-2-1989 and store it back into the List as a Timestamp. how can I do that.
I am trying to grab a graphical object from an arraylist, and reposition its coordinates on a Jframe when adding it. My program of course deals with strings, and once it sees specific words in my console, some method is called that adds, removes, or otherwises modifies certain objects on screen.
Here I want to say something like move(object[1],xpos,ypos) which will move a certain object from a specified point in the array, and move it to new x and y positions on the JFrame. I use a different class that extends a graphics program, so when I say add(something,x,y) it draws the object onscreen where I want it. These are some relevant, though incomplete, methods that should move an object already painted on screen:
Console class
Java Code:
public void doMoveCommand(String cmd, String arg, String xpos, String ypos) { int x = Integer.parseInt(xpos); int y = Integer.parseInt(ypos); if (cmd.equals("posMake") && arg.equals("star")) { box.moveStar(box.historyG.get(1), x, y); //historyG is an arraylist of GPolygons freeCommand();
[Code] ....
When I say makepos(whatever) I am getting a arraylist out of bounds exception. How I might be able to accomplish moving objects already on screen?
I would like to create a program that takes some files and modifies them in this way: The files should contain text formatted in this way:
############## #various comments# ############## something{ identifier=1234 anotherIdentifier=1235 anotherOne=12345 //and so on... }//I need only this
#Comments are sometimes made this way
somethingAgain{ #comments that explains what's below them I:dentifier:something, I, do, not, need #see ^that A:notherIdentifier:boolean //and so on.. }
And I have to make so that the numbers contained in something{} in all the files don't match. I could ask to make so that the input file is only one, and it is formatted this way:
identifier=1234 anotherIdentifier=1235 anotherOne=12345 //and so on...
but I don't know how to do the rest of the program... That's what I've done (the names of the classes, package etc. are in Italian and there's some useless code that NetBeans prevents me from deleting):
package confronto; import java.awt.Color; import java.io.*; import javax.swing.*; public class confrontoTesti extends javax.swing.JFrame {
how to structure simple programs (i.e. one-method algorithms for a simple purpose). There are a few different ways that I have been doing it, but I want to be consistent. Should I put both the one-method algorithm (e.g. a factorial function) and the main method that executes the algorithm into the same class and then export it to an executable .jar file for use? Or should I create one class for the algorithm and another for the main method that executes the algorithm? In addition, is there any reason that I should out these classes in a package before I export it?
As another similar question, if I have constructed two distinct classes with two separate purposes, and they are both used in the construction of a single program, then would it be best to just put the main method in a third, separate class or should I put it in one of the two classes?
I am new to jsf i have been given a task to create a tree structure in jsf but cant use richfaces and primefaces. I need a complete project for reference as i am to totally new to this.

The goal was to add a few buttons an add delete modify search and save. I feel like I have the entire need satisfied. I'm having a few symbol problems which I'm not quite sure how to fix.
which is directing me towards Prodname on the far right of the if statement. I'm not sure what the problem is. I've double checked my spellings several time for each spot and I cant quite get it.
Everyone has told me but I am aware that I made some bad decisions with the variables being capitalized this was my first go at a program and my instructor didn't let me know that thats the normal way to do it.
I am trying to Implement a method matchBracket(String exp), which should take a String expression consisting of only symbols (,[,{,<,),],},> , and checks if the brackets in the expression are matching using stack data structure.
I know how the methods of stack class like push,pop,peek are for however how to do the checking for opening and closing brackets iteratively ?
public static void matchBracket(String str){ // creating a stack of character at first Stack <Character> stack = new Stack<Character>() ; // starting loop to scan the expression below inside main method for(int i = 0; i<str.length(); i++){
[Code] ....
