What do you mean exactly? Should I start throwing random programming topics at you? [I]Persistence, multithreading,...[/I] Maybe random OOP topics? [I]Inheritance, polymorphism,...[/I] And what do you actually mean with "I know java better upto swings"? Was it topics on Java Swing that you wanted then? Try to explain a little …

> How does interpolation search work? Wikipedia explains fairly simply how it works: [URL="http://en.wikipedia.org/wiki/Interpolation_search"]link[/URL]. > Help me with how you end up with log(logN). Interpolation search is kind of an expansion on binary search because you pick a value, check it with the one you are searching for and based …

I'm afraid that at least that should be your job... Not only part of the "we only give homework help to those who show effort" policy, but from there on we'll have a better idea of what you're willing to achieve and therefor we will be able to help you. …

Ok, first things first... the way your code looks on this forum made my eyes hurt while trying to figure out what it does. Try to use less newline and shorter indents. As for the error, normally it comes with a line number so you should know at what line …

I've copied your code and it works perfectly. How do you have your files organized? Like this? -WorkerDirectory + Worker.java + HourlyWorker.java + SalariedWorker.java + WorkerTester.java Some package definitions lacking maybe? Black Box

Here you go, straight from the source: [URL="http://java.sun.com/docs/books/tutorial/"]link[/URL]. Great tutorials, well organized, you'll find anything in there you might need. Black Box PS: If you're new to programming, don't skip on getting to know all of the basic types and the bits and bytes behind them. Such knowlegde comes in …

You have two ways of doing that actually, do you want the user to give it at the startup of the program or at runtime? I'll assume that it'll be at runtime. You can use a Scanner witch reads from standard input to get the strings. Search in the API …

That's nice... The only thing is, we can't do it for you. If you come up with more specifications we can guide you, because at this point, "applet for create user - student & admin" isn't saying all that much. You have to show us that you are willing to …

It's best you start from the beginning when you want to start with GUI's. GUI building in Java is best done using Swing. The Java website provides great tutorials which will take you from the basics to where you want pretty quick. However, the do start out with the basics. …

It's a method, methods belong to objects of certain types. What is the type here? I want to help, but the name 'SlowMoveVertical' is a normal looking name that a lot of people already have used to create their own methods. Therefor, a google search isn't getting me anywhere unless …

If we would have had any suggestions at any point in time, we would have surely ran out of them by now, giving them to the 1385468413696434 final year students before you asking the same question... What I'm saying is... We can't decide that for you, once you have chosen …

You realise you are handing it back to the same button right (i.e. btnA1)?

For each possible outcome, you want to print out what its percentage was. You have everything you need to calculate that. You can store the number of dice rolls in a variable (or hand to the method, although it would be better to store). Then for each result you are …

I think that's right Ezzaral. If it *is* a constructor, you don't have to include void as a return type, since it's normal behaviour for a constructor to return an object of its class. Now onto that main method. Every program needs a main method so Java knows where to …

Just to give the solution to everyone (we worked it out over IRC). I think the getClass() method didn't really do what it was supposed to be doing. Instead using ClassName.class.getResource() did the job. Black Box

It might be easier to optimize once we know what it is that you're trying to do. We can see you're checking every item of a (10 000 x 10 000) table and replacing its value. But what is it for, why are you doing that? If you could give …

That's a good question. For this small amount of data you can work with cvs or xml files. Setting up the database and making it work in your code will take longer that doing so for the text files. However, parsing files is easy but it is slow, so if, …

Ok, I'm taking a look at it, but first you should know that when you post code, you should use the code tags like so: [code][ code ]leave out the spaces in the tags[ /code ][/code] and when you're using a specific language like you did (i.e. Java) you use …

You just cast it. In Java a char is actually just like an int, it only depends on how you use it. [code=java] // Declaration of char c, initialized with the character 'a'. char c = 'a'; // For int value of the character, cast to int: (int). int i …

Maybe you can post your code, or the bit that reads the file so we can see what you're doing. Maybe its a buffer overflow or something somewhere, not that it's a huge file, but still. (checked: 7.2 KB) Black Box

[QUOTE=cga2;483502]so that when there are same color balls i can eliminate them!!![/QUOTE] Did you really shout that loud while thinking of it to type the post? Anyway, if you have almost finished the code, post some of it here, so we can first of all see that you really have …

Actually, that isn't the solution. The way you say it makes it look like you have to do it right away. However, the problem was that he declared a variable and wanted to print it out at the end. His program had three different flows of which two did initialize …

There's also something wrong with your idea of declaring an initializing. Variables always need to be declared before you can use them. This simply means: say what it is. Type name; When you do it like that, the pc knows you want to use a variable AND it knows what …

For JavaScript questions you should post in the JavaScript forum, a subforum of Web Development. Java != JavaScript. Black Box

Ok, your method increment needs to increment that counter variable, which you aren't doing... There actually isn't anything wrong with the method getValue. Try to think about what should happen in the increment method and then post again what you have if it isn't working. [code=java] public void increment() { …

Actually, in C 0 always stands for false, but any other number stands for true (not only 1). I'm not sure about the other way, it is possible that for this direction C automatically returns 1 (instead of any number different from 0). However, knowing C it might be that …

You can PM me if you want.

Hehe. A classic. correctName = true != correctName == true The first one assigns true to your variable, the second one checks whether its value is true or not. Black Box
