Hi guys, could some one help me out trying to understand how hard drive seeking works. I have a small binary database file which read performance is absolutely essential. If I need to skip a few bytes in the file is it quicker to use seek() or to read() then discard the unwanted data. If the average seek time of a hard drive is 10ms an...
Say I have an enum which is just public enum Blah { A, B , C, D } and I would like to find the enum value of a string of for example "A" which would be Blah.A. How would it be possible to do this? Is the Enum.ValueOf() the method I need? If so, how would I use this? ...
Hello, for a programming assignment I have been asked to implement a solution to the Dining Philosopher problem. I must do so in two ways: Use the wait() and notifyAll() mechanism Using an existing concurrent data structure provided in the Java API I have already complete the first implementation. Which concurrent data structure is m...
/edit: thanks for the help so far, however I haven't got any of the solutions to take the sample input and give the sample output. My description isn't the clearest, sorry. I have an array composed of binary data. What I want to do is determine how long each unbroken segment of 1s or 0s is. Say I have this data: 0111010001110 In an ...
This is a doubt that arose in my workplace, and it should be pretty straightforward. We have two columns of numbers, say: 1 1 1 2 2 1 2 2 And we want to get the number of rows that have equal numbers (2), without a helping column for each comparison. We can't get a working matrix operation (wich is the way we think correct). Any idea...

I am developing the game worms (in the context of a university project), and I would like to know if there is any source code out there for a simple implementation of the game or any other game that derive/resemble to worms. The game is the old fushion one (back to assembly ones if you want), so any source code is welcome. ...
I have a college assignment due quite soon, and I need to be able to call a C++ dll that takes a long time (possibly infinte, it relies on user input)to execute. Im calling this through VB. My VB GUI freezes up when this happens, and I would like to keep the GUI responsive, so that the user can stop this possibly infinte loop. Can anyo...

This algorithm does a great job of traversing the nodes in a graph. Dictionary<Node, bool> visited = new Dictionary<Node, bool>(); Queue<Node> worklist = new Queue<Node>(); visited.Add(this, false); worklist.Enqueue(this); while (worklist.Count != 0) { Node node = worklist.Dequeue(); foreach (Node neighbor in node.Neighbors...
For my assignment I have to implement an RMI server which will a front end for two other RMI services. So I decided a logical thing to do would be to have the interface for this implement the interfaces for the other two services. public interface FrontEndServer extends Remote, BookServer, StudentServer { // Block empty so far } ...
How can I write a program in C which removes all the defined values defined by the user using #define name value? Throughout the program should we replace the name, value? Does anyone have any examples of this? ...
I've got a problem which I just can't seem to get around involving a small animation. For a project we are designing a J9 application to run on a PDA (DELL Axim X51). The problematic code (shown below) is when a mouse click is detected to run a small animation in a nested panel. If the animation is run independently of the mouse click, i...
Hi, We have an ant build script for a project we're developing for a PDA. In eclipse we have a load of referenced libraries and I know how to get them to work when we run the jar on the PDA because we have a .lnk file where you can add the external libraries simply by adding the following: 512#"\J9\PPRO11\bin\j9.exe" -jcl:ppro11 -cp "...

I'm looking for the most efficient way to figure out a change amount (Quarters, dimes, nickels, and pennies) from a purchase amount. The purchase amount must be less than $1, and the change is from one dollar. I need to know how many quarters, dimes, nickels, and pennies someone would get back. Would it be best to set up a dictionary? ...
