HELP WITH SOME C PROGRAM

I'll be very glad if anybody can help me solve this problem.
Implement in C the function int largest(const Node *r)
which, assuming that Node is
typedef struct node {
struct node * left;
struct node * right;
int value;
} Node;
and r denotes a binary tree, returns the largest value stored
in nodes of the tree.

Check out SortedMap.lastKey()All you need to do is write a Comparator for a node containing an int, and then set up the SortedMap correctly.

Help with some beginner code

Hello, I am new to java and I need a bit of help with some code that I'm writing. here is the code:
import javax.swing.*;
public class Test{
 public static void main(String[] args){
 JOptionPane.showMessageDialog(null,"We will now build a block with *'s","Block",1);
 String input=JOptionPane.showInputDialog(null,"Type a number: ","Number",3);
 int number=Integer.parseInt(input);
 int count=0; int count2=0;
 for(count2=0; count2<number; count2++){
 for(count=0; count<number; count++){
 System.out.print("* ");
System.exit(0);
}Now, all I need is to build a block of *'s with the number that the user inputs. With the code that I wrote I get the correct number of *'s but not in the form of a block. They just print out in a straight line. I know this is a very simple task but could someone please help me out? What do I need to modify in my code so that the *'s print out arranged as a block like so:
**********

Your code only uses the print method which prints without a carriage return/line feed. So you need to add a line of code to print a carriage return/line feed. Where? well that is your task to work out.

Help with a java program

Hello. I'm posting in these forums because I really don't know where else to go. I have been trying for the past several days to figure out how to go about writing my program but to no avail. The project requires reading many lines each containing several different elements from a datafile named "DATA". A few examples of some lines from that file:
Department number/Number of units received/Date on which the shipment arrived/Expiration date/Name of Object
0 78 02/03/2001 02/12/2001 apples
0 26 06/03/2001 06/10/2001 lemons
3 62 03/06/2001 03/14/2001 hamburger
What we have to do with this data is read all of it from the file, separate all the different elements, and based on input from the user, sort everything and print it out to the screen. If the user enters 03, the program will show everything that arrived and expired within the month of March, sorted by date.
It is a pretty basic program, but my problem is that I have no idea how to go about reading in this data, putting it into a vector (probably the easiest method) or separating the different elements. I've gone to websites and looked through my textbooks but they didn't help much. If anyone has any resources that could help for writing such a program, or if anyone could offer help in writing the program, I would really appreciate it. I can also show what I've managed to write so far, or more details on how the program should work. Thanks in advance.
Matt

since im not a pro like some of the guys on here :),
and believe me thiers people here, who could write your whole app in a hour.
anyways my advice , would be to do a search on the forums for useing.bufferReader()
i think you would need to read the file in with bufferreader then split up each line useing the stringTokenizer and then use some algorithm to compare
the values and split them up into your vector arrays as needed.
thier is also fileinputStream i think you can use that too.

Help with some java work ... :(

Hi, I was wondering can anyone here give me some help or show me the way with this programming assignment. This is my first week of programming in Java and is really struggling ...
I already have some very useful help from some people on here but still have no luck.
Below is what my assignment is about and what I've done so far, sorry if it's very basic but I'm trying my hardest.
You are required to write a program in Java that can store the details of three books. Their details are
Author
Shelf location
Availability
The program should give each book a unique shelf location starting from 0001. The details should be entered from the keyboard. The program should, on request, be able to print the details of each book to the screen. The program should terminate on request. The program should first ask for a preset password to be given before continuing executing any operation described above
public class Library {
public static void main(String[] args) {
String[][] books =
 { "Shelf Location", "Author ", "Book Name ", "Availability" },
{ "0001 ", "A. Smith ", "Hello World ", "1 " },
{ "0002 ", "C. Jones ", "Goodbye World ", "0 " },
{ "0003 ", "D. Wan ", "Whatever ", "5 " }
for (int i = 0; i < books.length; i++) {
 System.out.print(books[0] + " ");
for (int j = 1; j < books[i].length; j++) {
 System.out.print(books[i][j] + " ");
 System.out.println();
import java.io.*;
public class Login2
private static BufferedReader in;
private static BufferedReader keyboard;
public static void main(String[] args) throws IOException
keyboard = new BufferedReader(
new InputStreamReader(System.in));
String input;
boolean done = false;
while (!done)
System.out.print("Enter Password in UPPERCASE (QUIT to exit)");
input = keyboard.readLine();
if ((input.equals("LOGIN")) || (input.equalsIgnoreCase("QUIT")))
done =
true;
return.Library();
I was told to use cases, instances, etc ... nothing complicated is needed but it is still to much for me. I saw some examples of people's work and they only have approx 1.5 pages of code.
Thanx very much for people who reads this thread and offers me help.

Here's something to play around with (minimal error handling)
import java.io.*;
class Library
private final String password = "java";

private void options() throws IOException
 System.out.print("\nLibrary Options - \n0 - quit\n1 - Enter book details"+
 "\n2 - List book details\n\nPlease enter selection number: ");
 int selection = Integer.parseInt(br.readLine());
 if(selection == 0) goodBye();
 else
 checkPassword();
 if(selection == 1) newBook();
 else listBook();
private void newBook() throws IOException
 String another="";
 do
 if(bookTotal == books.length)
 System.out.println("Unable to add more books");
 return;
 books[bookTotal] = new String[4];
 System.out.print("\nEnter title details: ");

Need Help With D&D Program

Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
Sorry for the length. Thanks for any help you can give.

The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
     private static GraphicsConfiguration gConfig;
     private static Dimension compSize = new Dimension(80, 22);
     private static Image image = null;
     public static Image getImage(Class objectClass)
          if (gConfig == null)
               GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
               GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
               gConfig = gDevice.getDefaultConfiguration();
          image = gConfig.createCompatibleImage(compSize.width, compSize.height);
          JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
          jc.setSize(compSize);
          Graphics g = image.getGraphics();
          g.setColor(Color.LIGHT_GRAY);
          g.fillRect(0, 0, compSize.width, compSize.height);
          g.setColor(Color.BLACK);
          jc.paint(g);
          return image;
}And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
     private static DragSource dragSource = DragSource.getDefaultDragSource();
     private static DragGestureListener dgl = new DragMoveGestureListener();
     private static TransferHandler th = new ObjectTransferHandler();
     private Class compClass;
     private Image image;
     Dragable(Class compClass)
          this.compClass = compClass;
          image = JComponentImage.getImage(compClass);
          setIcon(new ImageIcon(image));
          setTransferHandler(th);
          dragSource.createDefaultDragGestureRecognizer(this,
                                                      DnDConstants.ACTION_COPY,
                                                      dgl);
     public Class getCompClass()
          return compClass;
}Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
     public static Object instantiate(Class objectClass)
          Object o = null;
          try
               o = objectClass.newInstance();
          catch (Exception e)
               System.out.println("ObjectFactory#instantiate: " + e);
          String name = objectClass.getName();
          int lastDot = name.lastIndexOf('.');
          name = name.substring(lastDot + 1);
          if (o instanceof JLabel)
               ((JLabel)o).setText(name);
          if (o instanceof JButton)
               ((JButton)o).setText(name);
          if (o instanceof JTextComponent)
               ((JTextComponent)o).setText(name);
          return o;
}Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
     private static DataFlavor df;
      * Constructor for ObjectTransferHandler.
     public ObjectTransferHandler() {
          super();
          try {
               df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
          } catch (ClassNotFoundException e) {

     public Transferable createTransferable(JComponent jC) {
          Transferable t = null;
          try {
               t = new ObjectTransferable(((Dragable) jC).getCompClass());
          } catch (Exception e) {
               Debug.trace(e.toString());
          return t;

          comp.add(c);
          comp.validate();
          return true;
public class ObjectTransferable implements Transferable {

}And of course the test class:public class DragAndDropTest extends JFrame
     JPanel leftPanel = new JPanel();
     JPanel rightPanel = new JPanel();
     Container contentPane = getContentPane();
     Dragable dragableJLabel;

      * Constructor DragAndDropTest.

          super(title);
          dragableJLabel = new Dragable(JLabel.class);
          dragableJButton = new Dragable(JButton.class);
          dragableJTextField = new Dragable(JTextField.class);
          dragableJTextArea = new Dragable(JTextArea.class);
          leftPanel.setBorder(new EtchedBorder());
          BoxLayout boxLay = new BoxLayout(leftPanel, BoxLayout.Y_AXIS);
          leftPanel.setLayout(boxLay);
          leftPanel.add(dragableJLabel);
          leftPanel.add(dragableJButton);

          frame.pack();
          frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

Help with a simple program.

I need some help writing a simple program. Can anybody help??
thanks to all.
2. HTML Java Source Code Reserved Word Highlighter
Write a program that inputs a Java source code file and outputs a copy of that file with Java keywords surrounded with HTML tags for bold type. For example this input:
public class JavaSource
public static void main ( String[] args )
if ( args.length == 3 )
new BigObject();
else
System.out.println("Too few arguments.");
will be transformed into:
public class JavaSource
public static void main ( String[] args )
if ( args.length == 3 )
new BigObject();
else
System.out.println("Too few arguments.");
In a browser the code will look like this:
public class JavaSource
public static void main ( String[] args )
if ( args.length == 3 )
new BigObject();
else
System.out.println("Too few arguments.");

Help with some fundamentals...

OK, still trying to play catchup after some years away from Java. I'm slowly getting back up to speed with the help of some of the gurus present on this site.
Here's the background: Working on examples from a Wrox book on JSP and moving to database connections. Programs compile fine but run into this NoClassDefFoundError. Here is a simple example:
public class HelloWorld
public static void main(String args[])
System.out.println("Hello World!");
Simple, heh? Compiles fine and when it is ran from the command line, this comes back:

}the only problem now is about how it should display the right info about the person whenever i click its name on the list.. something about file reading or something, i just cant figure it out.
and also about how to make it scroll once it exceeds the list.. i cant make it work, maybe something about wrong declaration..
thanks in advance..

Like said before, do one thing at a time. At startup, something like:
//put all the content in a list
ArrayList<String> lines = new ArrayList<String>();
while(String line=rand.readLine()!=null) {
 lines.add(line);
}If you follow the good advice to create a class to encapsulate the entries, you could populate a list of such entries like this:
static final int ENTRY_SIZE = 3;//you have 3 fields now, better to have a constant if that changes
ArrayList<Entry> entries = new ArrayList<Entry>();
for(int i=0; i<lines.size(); i+=ENTRY_SIZE) {
 Entry entry = new Entry(lines.get(i), lines.get(i+1), lines.get(i+2);
 entries.add(newEntry);
}You could also do both of the above in one run, but I think you will understand better what's happening if you do one thing at a time.
If you don't want to put the entries in an encapsulating class, you can still access this without looping:
int listStartIdx = <desired_entry_index>*ENTRY_SIZE;
String att1 = lines.get(listStartIdx).substring(1);
String att2 = lines.get(listStartIdx+1).substring(1);
String att3 = lines.get(listStartIdx+2).substring(1);

Need help with a rudimentary program

I'm sort of new at this so i need help with a few things... I'm making a program to compile wages and i need answers with three things: a.) what are the error messages im getting meaning? b.) How can i calculate the state tax as 2% of my gross pay with the first $200 excluded and c.) how can i calculate the local tax as a flat $10 with $2 deducted for each dependant. any help is appreciated
Here is what i have so far:
public class WagesAsign1
          public static void main(String[] args)
               int depend=4;
               double hrsWork=40;
               double payRate=15;
               double grossPay;
               grossPay=payRate*hrsWork;
               double statePaid;
               double stateTax=2.0;
               statePaid=grossPay*(stateTax/100);
               double localPaid;
               double localTax=10.0;
               localPaid=grossPay*(localTax/100);
               double fedPaid;
               double fedTax=10.0;
               double taxIncome;
               fedPaid=taxIncome*(fedTax/100);
               taxIncome=grossPay-(statePaid+localPaid);
               double takeHome;
               System.out.println("Assignment 1 Matt Foraker\n");
               System.out.println("Hours worked="+hrsWork+" Pay rate $"+payRate+" per/hour dependants: "+depend);
               System.out.println("Gross Pay $"+grossPay+"\nState tax paid $"+statePaid+"\nLocal tax paid $"+localPaid+"\nFederal tax paid $"+fedPaid);
               System.out.println("You take home a total of $"+takeHome);
and these are the error messages so far:
WagesAsign1.java:23: variable taxIncome might not have been initialized
               fedPaid=taxIncome*(fedTax/100);
^
WagesAsign1.java:29: variable takeHome might not have been initialized
               System.out.println("You take home a total of $"+takeHome);
^

edit: figured it out... please delete post

[8i] Need help with some workday calculations

At the beginning of the month, I got help with a workday calculation in: [8i] Help with function with parameters (for workday calculation)
Now, as it turns out, I was able to locate a function in the database that does what I want, however, it is much slower to use the function than to join two copies of the CALN table (Please see referenced thread for details. I can copy them to this thread if necessary.) I need to verify that the pre-existing function has 'DETERMINISTIC' in it, as I would guess that if it doesn't, it would be much slower than it could be.
But now, I've come across a situation where I have to do multiple workday calculations in the same query--enough that I have to join 6 copies of my CALN table. I can't imagine that is at all efficient. I believe it was Frank K. who said (in the original thread) that if the function was slow, I should consider alternatives. Can anyone help me identify some of those alternatives? I'm definitely at that point now. (This query is one I'm using as the base for a report in Oracle BI, and let's just say it doesn't like my query, even though my syntax appears to be correct, and I would guess that joining 6 copies of one table is at least partly to blame for this).
Note: I'm working with Oracle 8i

OK, I finally have some sample data... I tried to make it thorough. I've included data in the CALN table YTD + tomorrow, so that any workday calculations using SYSDATE will work.

Help with some transitions

Hello, i'm trying to do add some transitions to my video. I want to do a intro like this: http://www.youtube.com/watch?v=aBPV0f6c56s
I have already written the swords, the texts and the central anime minecraft guy with Anime Studio, but i need to do this 3 things:
1. Am expanding cirle opening
2. A light/flash as transition between the first animation and the next logo
(I have another question, but more difficult: I want to do a sun rays effect from an angle)
All of these effects-transitions are in the youtube video that i linked.
Can someone help me with one of these questions?
I have Adobe After Effects and Premiere Pro.
Thank you for the attention.

The circle wipe is just that, a transition. Look in Effects>Transition. I'll give you a clue, a circle has a radius... It's there along with some more interesting effects.
You can also do a circle transition with a simple animated mask, use a scaled round layer as a track matte or about a hundred other combinations.
The light burst effect can be done with a simple masked white solid blend mode set to add and opacity keyframes or by searching your effects and pre-sets for light b. You'll find it. Just add it to a solid between your layers, set the blend mode to add and use an animated mask and opacity to bring in the effect. (the yellow thing in the middle is the animated mask that makes CC light burst interesting.
Same thing can be used for your sun rays. It's just a matter of layering and the shape of your mask.
Here again, there are dozens of ways to achieve this effect.
If you're completely lost then start here. This is basic enough AE that you shouldn't really need a step by step tutorial to pull it off.
Or as dave suggested, get Anime Studio.

Help with some java login code

hey,
I am a new member but used to visit the site regularly. I am undergoing a java project and I cannot seem to get my head around how to code when users log in, there name must appear at the top of each page they visit.
User enters name into a text box. Do I use getter and setter methods? any bit of help would be of some advantage to me.
Thanks for your time and I'll help with anyone else who is stuck.

if JSP or servlet use Session...
if you are using frame you have to consider... which frame is a top parent. that top frame will have the set and get method.. for you to set and retrieve the user name.. bear in mind that different object will have different user...
so you have to play fair game ...hehehehe :-)
